In recent years and in many countries of the world increasing research and experimental work has been performed to find new, effective and economical displacing media in which the secondary exploitation of oil reservoirs may be performed and to increase the efficiency of recovery, the areal and volumetric sweep efficiency, and the recovery factor respectively.
A number of attempts have involved the use of carbon dioxide under pressure. Carbon dioxide, above a certain pressure level, is readily soluble in water, excellently soluble in oil and in the context of the present invention has the following effects:
1. Upon dissolution in the oil it increases the volume of the oil and thus leads to an increased relative oil saturation, to increased effectiveness of displacement of the oil and to increased recovery factor.
2. It decreases the viscosity of the oil, thereby increasing the effectiveness of the oil displacement and the efficiency of recovery, respectively.
3. It decreases the surface and interfacial tension, thereby increasing the effectiveness of displacement of the oil and the recovery factor, respectively.
4. It dissolves calcium carbonate binding material in sandstone and the rock material in limestone reservoirs, thus increasing primarily the permeability of the formation. Further it causes cross-flow and thus leads to increased surface and volumetric effectiveness of displacement and the recovery factor, respectively.
Whorton et al (U.S. Pat. No. 2,623,596) discloses the effect of the percentage of CO2 in a gas injected during secondary exploitation of an oil reservoir and the injection pressure on the percentage of oil recovered. In a series of tests with CO2 /N2 mixtures,it was determined that the minimum amount of CO2 in the mixture should be 50% and the minimum injection pressure 1,000 psi; preferably followed by the injection of an inert fluid. The use of 100% of CO2 is preferred but, if the availability of CO2 is limited, it is disclosed that other gases such as nitrogen, air, natural gas or any other gas can be mixed in. Whorton et al do not indicate any preference for one gas over another.
The effect of CO2 is in close correlation with the dissolution. Pure carbon dioxide is more soluble in oil, than the so-called mixed gas containing CO2 and a CH (hydrocarbon) component as well.
Under reservoir conditions, however, it is rare that either the oil or the dissolving gas is free of hydrocarbon gases. Under such conditions, the oil always contains more or less hydrocarbon gas dissolved therein or dissolved in the free gaseous phase. Naturally occurring carbon dioxide gas is what is called a mixed natural gas, containing hydrocarbons. Even if hydrocarbons are removed from the mixed natural gas prior to utilization of the carbon dioxide for secondary recovery of oil reservoirs, there will again be an admixture of hydrocarbon gas with the carbon dioxide upon injection of the carbon dioxide into the reservoir due to the CH components present in the reservoir. The solubility of carbon dioxide in oil is decreased by the presence of these hydrocarbon gases.
In view of the negative effect of hydrocarbon gases on the solubility of CO2 in oil, which is directly related to the oil recovery percentage, as shown below, it might be deduced that the use of N2 mixed with CO2 would be preferable to natural gas as a diluent, if a diluted CO2 was desired for injection into the oil reservoirs for secondary exploitation. Therefore, it was surprising to discover that, on the contrary, hydrocarbon gases are superior to nitrogen as a diluent in such applications.
The invention is based on the discovery that hydrocarbon gases are much more preferable to nitrogen as diluents for CO2 injected during secondary recovery of oil reservoirs. Larger amounts of CH gases at lower pressures can be employed to obtain oil recovery yields comparable to those obtained using nitrogen as a diluent.
Accordingly, the invention relates to the use of from 5 to 35%, preferably 10% to 30% hydrocarbon gases as a diluent for CO2 injected into the reservoir while maintaining a reservoir pressure of at least 100-120 atm, respectively, up to 250 at n, preferably 120-200 atm. The hydrocarbon gases may be injected with the CO2 or use may be made of the ambient hydrocarbon gases already present in the reservoir.
The invention will be illustrated in connection with the accompanying drawings in which

FIG. 7 shows the production history of a well described hereinafter as an example; and
FIG. 8 shows a comparison of the oil recovery obtained at various pressures using CO2 gas mixed with N2 and with CH gases.
In FIG. 1, the solubility of the injected gas at a constant pressure is designated on the ordinate at Rso, in standard cubic meters per cubic meter of stock tank oil. The ratio Bo of the volume of oil containing dissolved gas, compared to oil with no dissolved gas is also designated on the ordinate. Pressure in atmospheres is shown on the abscissa, while the constant composition lines show the percentage of carbon dioxide.
It should also be understood that the constant composition curves containing CO2 of FIG. 1 refer not merely to the injected gas but rather to the composition of the gas after injection, that is, after mixing with the ambient hydrocarbon gases present in the reservoir. It will also be noted from FIG. 1 that solubility of the mixed gas at a constant pressure decreases with decreasing carbon dioxide content. In considering the data depicted in FIG. 1, it should be borne in mind that an increase in the amount of CO2 dissolved in the oil (Rso) results in a corresponding increase in Bo. This is proportional to the increase of oil saturation, which in turn is proportional to the displacement of oil into the production well, i.e., the % oil recovery. According to FIG. 1 it has been found that in the case of an injected natural gas having 81 vol. % CO2 content, up to about 30 atmospheres, there is no significant difference in the values of Rso and Bo in the case of pure CO2 (point 1) and pure hydrocarbon gas (point 2, principally methane). The curves diverge between 30 and 60 atmospheres, at points 3 and 4, respectively; while above 60 atmospheres, the percentage of CO2 is quite important. Notice that the 50% CO2 line is almost straight, that is, the rate of change of Rso and Bo with changing pressure is constant. Above 50% the curves are upwardly concave and below 50% they are downwardly concave. Unless otherwise indicated, % values of gases refer to % by volume.
The 50% CO2 line indicates that the ratio of CO2 and CH gases in the reservoir is 1:1. This is a critical line as under this line Bo and Rs increase at a smaller rate with increasing pressure and thus the efficiency of CO2 gas cannot be improved as described. The curves show that at, say, 80 atmospheres, with pure CO2 gas 137 m3 dissolves at 68° C. (point 5); while in pure hydrocarbon gas 60.5 m3 dissolves (point 6); and 88 m3 with 65% CO2 (point 7). Thus, to reach a dissolution rate corresponding to pure CO2, in the case of a gas containing 65% CO2, instead of at 80 atmospheres, a reservoir pressure of 120 atmospheres would be used (point 8); while at 50% CO2, 150 atmospheres are required (point 9).
It will be apparent that if the reservoir does not have a gas cap, and is depleted, its hydrocarbon gas content, both free and in solution, will be at a minimum. But should the reservoir possess a gas cap, and its content of dissolved gas also be significant, then the injected gas should have a higher carbon dioxide content.
Thus, e.g. if the total amount of CH-gases in the oil-reservoir is 100 million cubic m (Mm3), the same amount of pure CO2 gas has to be injected to achieve at least the 1:1 ratio of CO2 :CH in the reservoir.
If a gas containing only 65% by volume of CO2 can be injected, 350 Mm3 of such gas has to be injected. In this case the reservoir contains 225 Mm3 CH gas and 225 Mm3 CO2, which means 50% CO2 in the reservoir.
If by the amount of 350 Mm3 of gas the original reservoir pressure is attained, so also 350 Mm3 of pure CO2 has to be injected to achieve the original formation pressure. In this case, however, the reservoir contains 100 Mm3 of CH gas and 350 Mm3 of CO2, i.e. the CO2 content of the gas in the reservoir will be 77.8%, giving a favorable result, as can be seen in FIG. 1. If the original pressure is achieved by the injection of 100 Mm3 of gas, so in the case of a gas containing 65% CO2, the formation pressure should be increased to the value obtained by injecting 350 Mm3 of gas. That means that if the parameters of a given oil reservoir on the ordinate of FIG. 1 are known, the formation pressure ensuring the achievement of at least 1:1 ratio of CO2 :CH gases can be read from the abscissa of FIG. 1. It also follows that the reservoir pressure should always be increased by the gas to be injected, except, when it is not possible due to unlimited water supply. The pressure is increased by water according to processes known per se. Increasing pressure by water, however, changes the saturation relations, and increases the water saturation of the reservoir, which is a disadvantage. According to the present invention the pressure is increased by the injected gas, whereby the water saturation is not increased and simultaneously the favorable effects of the CO2 on the reservoir, the reservoir liquids and the dissolution of CaCO3 are seen in the course of the gas injection.
FIG. 2 shows schematically a geological cross section of a formation having shale beds 34 surrounding the oil bed 13. The water is shown at 15 and the oil zone at 13, the water-oil interface being at 18. Injection wells 11 and production wells 12 are provided, the bottom ends 33 of which are located in a shale bed 34. Carbon dioxide gas emerging from the perforations 14 in the side walls of well 11 passes into oil body 13. Crude oil flows through perforations 35 into production wells 12 and thence to the surface.
The oil bed or formation 13 is in effect a reservoir possessing an intergranular porosity. The pore space, a sectional view of which pores is shown in FIG. 2a, has an actual size of about 10-2 to 10-4 mm. The pore is limited at 21 by the interface of rock grain and/or cementing material. The connate water film is shown at 23, the effective pore volume being within this film and at the beginning of production it is filled only with oil. In the course of primary production, part of the oil will be driven out of the pore. During secondary production, when the oil is further displaced by gas, the effective pore volume is filled by the residual oil 24 and by the moving gas phase 19.
In FIG. 2b there is shown a top view of the formation between an injection well 11 and a producing well 12, the wells 11 and 12 being located in a conventional grid pattern. Phantom line 29 shows the area in which the gas 19 has displaced the oil 24 from the pores.
As indicated above, the carbon dioxide containing gas passes along the paths indicated generally by the arrows 37 in FIG. 2 towards the perforations 35.
In FIG. 2b is shown the situation in which the injected gas, whose boundary is indicated generally at 28, may break through into the production well 12, through the shaded area 32. Shutting down the production well, however, causes the shaded area 32 to become saturated with oil and so the breakthrough is cured.
While the production wells are shut down the gas injection continues until the formation pressure--as indicated in FIG. 1--is reached.
After the necessary reservoir pressure has been reached, water is injected through well 11, which follows the previous flow paths of the gas to the surface through production wells 12. The pores adjacent to the injection well 11, in addition to the connate water 23, will be filled with residual oil containing heavy components and by the injected gas containing carbon dioxide. At the onset of water injection, the injected water dissolves the carbon dioxide gas in these pores and becomes saturated with carbon dioxide. As this water saturated with carbon dioxide moves in the direction of the arrows 37, the part of the gas which cannot be dissolved by the injected water will be partly displaced by the water and partly will remain behind as residual gas which will then later be dissolved into further injected water. The water thus saturated by carbon dioxide is shown in FIG. 2a at 25 and will displace the oil 24 which has also become saturated with carbon dioxide in the same way. In FIG. 2b, that area which can be water flooded is bounded by the limits 31.
Referring again to FIG. 2a, it will be noted that the calcium carbonate cementing material dissolved by the carbon dioxide is indicated at 22 and is located at the narrowest portion of the pore throat where the carbon dioxide velocity is the highest. Although the dissolution of the calcium carbonate material of the rock is relatively small, the enlargement of the pore throat is, nevertheless, significant; and the resulting increase in permeability has a very significant and favorable effect on secondary recovery.
FIG. 3 shows an oil zone and a gas cap at 16, with the gas-oil interface at 20. The perforations 14 of the injection well 11 open both in the gas and in the oil zones. The perforations 35 in the producing wells 12 are only in the oil zone 13.
CO2 -containing gas is injected into the gas cap in order to increase the reservoir pressure and in order to reach the desired CO2 :CH ratio in the gas cap containing CH which otherwise decreases efficiency.
Water injection, like gas injection, is thereafter conducted in both zones 13 and 16. The displacement of the oil and water saturated with carbon dioxide will take place in the same way as with FIG. 2. However, in addition to the function of FIG. 2, FIG. 3 has the characteristic that the water injected into gas cap 16 can dissolve only a part of the carbon dioxide existing as a free gas phase, the rest of the carbon dioxide in zone 16 being compressed and forced into zone 13, which further favorably affects the recovery in the oil zone.
FIG. 4 shows an oil zone 40 in a limestone reservoir. The pore space has a compound porosity comprised not only by the pores of the matrix, but also by a system of fractures. Gas is injected as before, through the injection wells 11 and thence to the production wells 12 and 38, whose perforations 35 are located above the original contact 18 between the oil and the water zones 36 in the oil zone 40.
FIG. 5 shows a formation having sandstone reservoirs 13 and limestone reservoirs 40 with unlimited water supply. Upon production, water from the water zones 15 moves into the zones 13 and 40. In zone 15 residual oil is to be found after the water displacement which can be decreased with CO2 injected through perforations 14 of the injection wells 39. The perforations 14 of the injection wells 11 and 39 are above the original water-oil contact 18. Upon injecting gas through the perforations 14, while no water is injected, the water-oil contact region remains stationary; but after gas injection is completed, then the saturated oil will be displaced by the pressure of the encroaching water from zones 15, thereby to force the oil through the perforations 35 of the production wells 12 to the surface. The water encroachment, however, is limited by the remaining injected gas. The water encroaching from zones 15 due to unlimited water supply replaces the water injection after the gas injection and so there is no need for subsequent water injection.
FIG. 6 is a graph of gas-oil ratios on the ordinate versus time of exploitation on the abscissa. FIG. 6 can also be related to FIG. 1. Thus, for a pressure value of 100 atm. and a carbon dioxide content of 50%, as shown on FIG. 1, Rso =94 m3 /m3. This is shown as point 61 in FIG. 6 which designates the gas-oil ratio of 3.9×94 or 329 m3 of gas per m3 of oil. If the carbon dioxide content is 65%, then at 100 atm. Rso =112 m3 /m3 ; which when multiplied by the gas-oil ratio at point 61 provides a gas-oil ratio of 382 m3 /m3.
At the onset of injection of the carbon dioxide gas, the production wells can have gas-oil ratios of widely differing value, that is, between 200 and 3,000. If in the course of carbon dioxide injection this initial value increases by, say, 30% for example, from 3,000 to 3,900 m3 /m3, and the CO2 content in the gas produced reaches 30-50%, the well must be shut-down. These conditions are indicated at 62 in FIG. 6.
After shut-down, with further passage of time, the conditions are represented by point 63 in FIG. 6; but again, the gas-oil ratio can increase until point 64 is reached, at which point the well must again be shut-down.
With further regard to FIG. 6, continuous production is most advantageous at gas-oil ratios corresponding to 65 in FIG. 6. However, production is also effective and economical between points 63 and 64 in FIG. 6.
In the course of oil production in oil reservoirs another important parameter apart from the gas-oil ratio is the water content of the produced fluid. Different types of reservoirs can be in a different state of wetting when starting gas injection. The water quotient of the produced fluid may be in the range from 0 to 100%. In the case of wet reservoirs the production wells have to be operated after having started the CO2 injection even if it contains 100% of water at the beginning. Upon injecting CO2 the water content of the produced fluid decreases as an oil zone is formed.
In correlation with FIGS. 2b and 6 the water content may increase when the well is shown-down in order to stop gas breakthrough and it may decrease when opened again, as shown by the water % curve 75 in FIG. 7. After the CO2 -containing gas injection, in the course of water injection the injected water breaks through after a while into the production wells, whereafter the water content is gradually increased, though the pore cross-section is increased by CO2 and therefore this period is characterized by a certain fluctuation. CO2 enters the smaller pores (later by molecular diffusion) and the oil is displaced from the pores by CO2 dissolving the calcium carbonate binding material in an increased cross-section when water is flowing in the larger pores. Thus the further oil gets into the water flow, the water becomes oily and the water content of the production well becomes unstable. That is why it is important to operate the production wells after the breakthrough of the injected water (following the injection of CO2 containing gas) to achieve at least a 40:1 water-oil ratio.
Several experiments were carried out to investigate the process and efficiency of oil displacement with CO2 using gas mixtures of different CO2 content corresponding to different reservoir types and relations. All the experiments investigating the effect of the rate of displacement showed that the recovery was increased by increasing the rate of displacement.
The following laboratory results were obtained at 68° C. and 100 atm. using a gas of 81% CO2 content under the conditions of a reservoir given below in the Example:
______________________________________V(m/day) (%) Sor______________________________________0.50 58.0 29.022.92 62.2 26.1112.91 66.1 23.4364.56 70.3 20.5______________________________________ where: V = rate of displacement, m/day (%) = efficiency of displacement, % Sor = residual oil saturation at surface volume, %.
The above data show that the residual oil saturation decreases with increasing flow rate.
When injecting the carbon dioxide-containing gas at a high velocity into the injection wells 12, as shown in FIGS. 2 to 5, the gas flows through perforations 14 with high velocity in the course of which it not only displaces the oil but also vaporizes residual oil of the pores as well, carrying the vaporized oil along with it. More closely adjacent to the production wells 12 even more oil vaporizes into the gas and thus becomes saturated. As the radius from the well 11 increases, the velocity decreases and at a certain point oil will no longer be vaporized by the saturated gas. Moreover, moving away from the injection well, as the carbon dioxide progressively dissolves in the oil of the pores, the oil components again segregate out of vapor phase.
The oil saturation of the pores increases not only due to the swelling resulting from dissolution of carbon dioxide, but also by what might be called condensation of the previously vaporized oil. Thus, in a direction from well 11 to wells 12, the saturated gas is progressively replaced by oil saturated with carbon dioxide, as indicated schematically at 25 in FIG. 2a. The carbon dioxide, of course, saturates the primary residual oil of the pore as well.
The conventional gas injection is carried out at a distance of 10 to 15 m from the injection well at a maximal flow rate of 0.5 m/day, due to which the undissolved gas flows away in the front without forming a fluid-oil plug. The low flow velocity behind the front does not carry along oil, which would form an oil plug after condensing the front. The fluid collected in the front forms a plug, the displacement of which causes an increase of the pressure in the front and behind it. At a high rate of injection the pressure in the front and behind it increases and the moving of the fluid-oil plug is carried out at a higher pressure. This can be seen in FIG. 7, the pressure increased in the production well during the breakthrough from 30 atm. to 100 atm. within 1-2 days. This phenomenon of the high rate of injection is of great importance in increasing efficiency. The injected gas flows in a space of high pressure and is thus efficient and promotes the formation of the front.
We have found that if the injection velocity is high only at a distance of 10 to 15 meters from the injection well, the gas does not vaporize as much oil as could form an oil plug condensing at the front. The injection at high velocity has to ensure a flow velocity of 3-12 m3 /day even in a radius of 75-100 m corresponding to the laboratory data mentioned above.
The high rate of injection has to ensure that the progressing velocity of the front decreases the residual oil saturation formed by the conventional low rate injection up to a radius of 75-100 m. That is, instead of the 0.5 m/day velocity corresponding to the low rate of injection, the progressing velocity of the front should be 3-12 m3 /day up to a radius of 75-100 m. Thus from a distance of 75-100 m from the injection well sufficient oil leaves in order to form a front. As the flow velocity can be provided by the injection rate, the velocities mentioned above can be provided by the rate of injection. Thus the injection rate values are those critical values which are indispensable to ensure the aforementioned effects i.e. the 500-1,000 m3 /day/m flow formation thickness.
The flow formation thickness is a part of the total formation thickness available for the flow:
hf =ht ·φ·Sg
hf =flow formation thickness, m
ht =total formation thickness, m
Sg =gas saturation
The more usual formation thickness value amounts to 40-80 m3 /day/well/m.
To enable those skilled in the art to practice the invention the following non-limiting example is given:
In the deep portion of the Budafa field, a mixed gas reservoir containing by volume 82% CO2, 0.4% H2 S, 14% methane and 3% nitrogen and heavier hydrocarbons was discovered at a depth of 3,000 m in 1968. The reservoir having produced since 1937 had been subjected to primary production and lay at a depth of 1,000 to 1,100 meters and is limited by a bounding fault and by wedging and is in contact with a water saturated formation but there had been no water encroachment during primary production. The formation consists of quartz sandstone containing 26% by weight calcium carbonate as cementing material, and has a porosity of 21.5%, a permeability of 25-30 mD, and an average thickness of 8 meters. The reservoir oil is a bright light oil, which at the original pressure was saturated with gas. During primary production there had been performed an injection of hydrocarbon gas, and afterwards a water injection. The injection of the hydrocarbon gas increased the cumulative recovery factor by 8.8 % and the water injection by 3.8%.
After these steps the onset of injection of carbon dioxide-containing gas can be seen in FIG. 7 indicated by the dotted line 78 above 1969 July.
To the left of the dotted line 78 the change of the parameters before the injection of the carbon dioxide-containing gas, and to the right the change of parameters under the gas injection and the subsequent water injection can be seen. Thus, e.g. curve 74 in FIG. 7 shows that before the CO2 -containing gas had been injected the reservoir pressure was 23 atm. and when the gas injection was finished--February 1970--the pressure was 120 atm. In FIG. 1, on the 0% CO2 curve BoCH =1.115 and RsCH =25 m3 /m3 corresponds to 23 atm. formation pressure.
At the attained 100-120 atm. bottom hole pressure, the carbon dioxide component increased to 65% so that the gas dissolved in 1 m3 of reservoir oil was 112-138 m3, of which 68.8 to 89.7 m3 was carbon dioxide. The value of Bo was 1.325-1.395, in contrast to the initial value of 1.115.
Formation pressure curve 74 of FIG. 7 shows that the formation volume of the injected gas has to be calculated at least at 100 atm.
The injection rate calculated on flow formation thickness:
ht =12 m
hf =ht : φ·Sg =12×0.215×0.30=0.774 m, i.e. 0.774 m of the 12 m thick formation is available for the gas flow rate.
Converting the injected amount to 1 m flow formation thickness:
Q=q/hf =800/0.774=1030. The value when rounded off gives 1,000 m3 /day/well/m flow formation thickness. Coming back to the laboratory displacement experiments it follows that the 40-80 m3 /day/well/m formation thickness injection rate is by an order of magnitude higher injection rate than the conventional injection rate.
The quantity of the injected gas was 35-40 times the quantity of oil, gas and water which had been produced during gas injection, calculated on the reservoir volume. The reservoir pressure (Pr) increased as on curve 74. As is shown by curve 72, the gas-liquid ratio (G.L.R.) increased; the curve of oil production shows that from 1.4 m3 per day (point 79) existing before injection, there was an increase to 10 m3 per day (point 80). Thereafter, the water content of the produced fluid, as shown by curve 75, decreased from 30% (point 81) to 10% (point 82) and then to 1 to 2%. The carbon dioxide content of the produced gas reached 65% by volume (point 83), as shown by curve 76.
On graph 71, it will be seen that between October 1969 and June 1970 there were only a few producing days per month. Thus the gas-fluid ratio is high, as at point 84 on graph 72. The high values of oil production (point 85) during this period are characteristic not of continuous operation but only of short test productions. Continuous production began in July 1970 (point 86). Because of the low water cut, the gas-fluid ratio was almost equal to the gas-oil ratio. At this time, the value of the gas-fluid ratio on FIG. 1 (point 87) was 128 m3 /m3.
FIG. 7 also shows that during the period of continuous production (point 88) the gas-fluid ratio corresponding to the gas-oil ratio at point 89 had desirable values for a number of months. Later, when the gas-fluid ratio at point 90 surpassed the four-fold value of the solution gas, at a pressure of 108 atm. at 121 m3 /m3, corresponding to the given pressure, the well 12 was again shut down.
On curve 77 of the cumulative oil production (Qo) (right hand ordinate of graph 73) it will also be noted that during the period of shutting-down because of high gas-fluid ratio, in the course of the test production, more oil had been produced (1,340 m3) than if the well had been producing throughout with the rate existing before gas injection (270 days, 380 m3).
The quality of the oil thus produced, throughout the entire production, during periods of both high and low gas-fluid ratio, and the specific gravity of the oil and its content of light ends remained substantially unchanged. Thus it was apparent that the carbon dioxide displaces from the formation not only the light components of the oil but also the heavy ones. It is apparent, therefore, that not only the viscosity but also the interfacial tension of the oil is reduced thereby facilitating its displacement.
The well illustrated by the above Example produced for the period of 41/2 years up to the end of 1973, more than three times its production during the previous eight years. The recovery factor of the reservoir increased by 12%.
A comparison was made of the effect of dilution of CO2 with hydrocarbon gases and nitrogen on the production rate in secondary recovery of oil at varying reservoir pressures. Mixtures of nitrogen and hydrocarbon gases were also studied.
______________________________________PRODUCTION RATE (%)/PRESSURE (ATM)100 120 150 200 250 300 350 400 500______________________________________CO2 /CH% CO265 72 84 93 97 9870 80 89 95 98 9875 86 92 96 98 9880 92 94 97 98 9885 94 95 98 98 98100 95 96 98 98 98CO2 /N2% CO265 76 78 79 81 90 97 9870 80 81 83 84 94 98 9875 83 84 86 88 97 98 9880 85 87 88 92 98 98 9885 88 90 91 95 98 98 98100 95 96 98 98 98 98 98N2 /CH% N265 42 43 44 46 51 57 68 94 9870 47 48 49 51 56 62 76 96 9875 51 52 53 56 59 68 84 97 9880 55 56 57 59 64 74 89 98 9885 57 58 59 61 67 82 95 98 98100 59 60 61 64 81 94 98 98 98______________________________________
The above data for the CO2 /CH and CO2 /N2 mixtures are plotted in the graph form in FIG. 8.
As can be seen from the above table, mixtures of nitrogen and hydrocarbon gases were not effective except at very high pressures. Likewise, mixtures of CO2 /N2 required higher pressures and a higher percentage of CO2 to give as high yields as CO2 /CH mixtures. It can be seen from FIG. 8 that the greatest dilution by CH, i.e. 65% CO2 provides unexpectedly greater oil recovery ranges from above 107 atm. up to 250 atm., over the corresponding CO2 /N2 mixtures. By comparison, however a natural gas mixture containing CO2 which is readily available in oil fields, frequently ambient or in situ can be used advantageously in the present invention.
Although the present invention has been described and illustrated in connection with preferred embodiments, it is to be understood that modifications and variations may be resorted to without departing from the spirit of the invention. Such modifications and variations are considered to be with the purview and scope of the present invention as defined by the appended claims.

Above the Rim, Below the Rim
[Bryce Canyon National Park, UT]
Sunrise over Bryce Amphitheater is a quintessential Bryce Canyon National Park experience. Sunrise was at 7 am today, which meant another 5 am-ish wake-up for us. The clouds that had sabotaged Chris’s night shots the night before now provided for an absolutely spectacular sunrise. In some ways, a cloudless sky would have been better because the morning sun light would have hit the hoodoos directly, thus providing an ever-changing color extravaganza for us to enjoy. However, the storm clouds were super nice too. We got to see all kinds of crazy reflections in the clouds, and the light changed from one minute to the next.
Once it was already bright, we set out to cover the bottom 1/3rd of the Rim Trail. This 5.5-mile trail hugs the rim of Bryce (hence the name), starting at Bryce Point where we saw the sunset and running almost to the northern boundary of the park. We didn’t have time to cover the entire 5.5. miles so we decided to do the portion that took us to Sunrise Point, where we planned on picking up the most popular trail in Bryce, the Queens Garden/Navajo Loop combination.
The Rim trail was breathtaking. It was aptly named, as we were pretty much on the edge of the rim the entire time. Looking ahead was especially harrowing, as we could see the steep drop offs that were just steps off the trail. This is probably where we both took them most pictures, as every few steps we had a different angle at the gazillion hoodoos and canyons below. We saw many erosion-carved arches and windows, tons of oddly shaped hoodoos that seemed to defy gravity, ridges and canyons and even a trail that we suspected was our trail’s opposite, the Under-the-Rim trail.
On many occasions we also saw trees that were literally hanging on to the edge, with most of their roots already having lost footing and just hanging in the air.
One thing we didn’t see over this almost 2-mile stretch? People! Once we left the overlook at Bryce Canyon, we didn’t see any other hikers on the trail until we got to the next scenic overlook. We were amazed that nobody else ventured out on this beautiful section of Bryce, especially since the Rim trail is super easy – it actually starts at a higher elevation than it ends, making for a very gentle descend all the way. But we didn’t mind. At one point it was so quiet around us that Chris belched out a startling “Hello”, which eerily echoed over and over again around us.
Once we got on the Queens Garden/Navajo loop combination trail, we finally saw lots more people. This trail allowed us to descend down into the canyon floor and marvel at all the hoodoos from below.
We passed what looked like a mini-version of a landmark hoodoo, Thor’s hammer, and we passed through several arches carved out in the limestone.
Once on the canyon floor, we walked past the now dry Bryce creek, and got on the Navajo trail before ascending the steepest section of it, Wall Street. We couldn’t believe the size of Wall Street. We felt like we were in a narrow canyon, with hundreds of feet of rock towering on both sides of us. The sky was nothing but a little blue sliver right above us, and the trail quickly vanished in favor of man-made steps and switchbacks – that’s how steep the ascent was. This and the rim trail were definitely the highlight of our hiking today at Bryce.
Before we topped out on the rim, we took a quick detour towards the actual Thor’s Hammer, then took a few parting shots of the hoodoos below us.
We both felt that we’d seen a truly unique place, unlike anything else in the world, and we were happy that our hikes gave us such a close and personal look at this magnificent place. Ominous clouds sent us off on our shuttle ride back to the car, and before long the sun that lit the tops of Wall Street for us just 30 min before was now replaced with pretty steady rain. We were so lucky to miss it!
In the afternoon, it was time to head back to Zion (about 2 hours away) for 3 days worth of amazing hikes and adventures through canyons. Until then!

And, keeps update it whenever any changes made to that pages.
Technically, this process called the search engine crawler system.
Maybe, your deleted blog posts should have crawled and indexed by the Google search engine to perform a deleted blogger post recovery.
How long does Google take to index a new page?
Well, it depends upon the search engines crawl rate for a blog and which is something depends on robots.txt file.
If a blog gets many fresh contents on daily basis, there are high chances for a higher crawler rate.
And, newly published posts usually crawls and indexes within an hour or even in a couple of minutes. However, if you don’t release new articles daily, the crawl rate may be slower.

German Transports Viewers With His Everyday Empathy
Anybody who’s ever used a camera — and in this digital age, cameras are as ubiquitous as the cell phones in which some of them reside — is to some degree a photographer looking for that perfect picture.
Photographers are always on the lookout, though the cell phone camera might be a schizophrenic distraction more than anything else. Nonetheless, the world is cast in a different light through a lens — the homeless person in an alley, the alley itself, worn fences, painterly clouds in a blue sky, the blur of a speeding car or the tangled branches of a forest. All the world’s a picture and everything we think is old becomes new again — it just takes a little patience to see it.
The young German photographer Bernhard Fuchs seems to have that patient eye, along with a discerning thoughtfulness and enduring appreciation for memory and landscape. He sees in a dirty gully of downtrodden grass the beauty that most others would overlook or quickly forget.
This of course is the rallying cry of any artist: to be empathic with the entire world, whether it’s a beat-up Ford sedan or a spiffed-up Corvette, a prickly bush or a majestic oak tree. Fuchs, in his latest photography book “Roads and Paths” — a 16-photograph selection of which is now on display at the Goethe-Institut — continues on his own artistic path, which began with a book of portraits and evolved into a series of photographs depicting abandoned cars and vehicles.
“Roads and Paths” are contained in 60 images taken in and around Helfenberg, Austria, Fuchs’s prosaic hometown, not too different from any other place. His portraits featured residents of the area, while his 11-inch-by-11-inch landscapes captured abandoned trucks, speedsters, SUVs, sedans and small cars.
But whether human or machine, what Fuchs sees through the lens is clearly precious to him. Over a span of five years, he patiently observed and recorded the landscape of his birthplace with a quiet, reverent eye. The resulting images are striking, though not necessarily beautiful in the traditional sense of the word. There are no fancy shadows gifting a road with meaning, no sunlight touching grass or meadows with miracles, no obvious sort of artifice. Instead, there’s a very intimate modesty at work here, hard to describe but equally difficult not to be affected by, in a delayed-reaction kind of way. You have to stick it out, stand there an extra minute, and let the images bleed into your mind.
Just consider the subject matter among the 16 chosen photographs: roads, paths, crossings, forest footpaths, snowy embankments and fields. There’s not much poetry here — just the well-worn function of a piece of road, grass on either side, a field covered in snow, or a dense array of trees. These are the things we see every day and they register to some backyard space in our minds, an attic of no significance. We don’t note them except for maybe a pretty sapling, sure, but not the plain cement or even the cracks in the sidewalk. We just walk over them, physically and visually.
But not Fuchs. His roads and vehicles, left behind, still seem alluring. They are out of place among the trees, the dirt, the furrowed field, the indentation against the highway — yet that’s precisely what brings them into sharp focus.
The images in “Roads and Paths” are singular because they’re almost invisible, worn out by the weather or by our hands and feet. They fade but that’s part of their indelible beauty, as they hum quietly along with the careening of time.
Fuchs takes the road less traveled by paying homage to that road, and everything on and around it. He sees a well-worn path or a tired old car for the first time all over again. And in this way, he drives our own imaginations and forces us to look at everything anew, from the ground up.

Problem: Since 2000, hospitals have provided more than $702B in uncompensated care to their patients. Moratoriums on
elective surgeries and related procedures during the pandemic have disrupted revenue projections, creating additional
financial pressure on hospitals. The need to explore unknown sources of recovery has never been greater.
Market: Our focus is the application of our Mass Tort Recovery Program on the “end stage” of the revenue cycle for our healthcare clients, when accounts go to self-pay or write-off.
Patient Advocates: We recover revenue from Tort Litigation / Multi-District Litigation settlements. The patient’s right are preserved and they participate in settlement distribution.
Hospital Advocate: We identify and protect our hospital clients’ right to recover a portion of the uncompensated cost of care rendered related to pharmaceuticals, medical devices or consumer products tied to Mass Tort Litigation / Multi-District Litigation.
Proprietary Technology: Our proprietary Mass Tort algorithms identify current or former patients who likely meet the damage criteria necessary to successfully enroll in applicable Mass Tort Litigations.
Compliant & Secure Services: Our HITRUST CSF certified data analytics and outreach services are HIPAA compliant and secure.
Allēus helps healthcare providers and employer-sponsored self-insured health plans recover third-party liability
revenue from a non-traditional revenue source – mass tort litigation.
Compared to traditional insurance subsets such as auto and worker’s compensation, mass tort recoveries from defective drugs, medical devices and consumer products can represent significant revenue recoveries. Because the recovery process is complex, most hospitals and health systems have not pursued these opportunities. Until now.
We leverage extensive healthcare, finance, and legal industry expertise to assist healthcare providers and employer-sponsored self-insured health plans understand their recovery rights and deploy this unique recovery program.
Our proprietary, HITRUST® certified technology platform, advanced analytics, and patient-centered advocacy services qualify potential high-value mass tort recovery opportunities through a targeted analysis of provider uncompensated or undercompensated care data, associated clinical encounters, or self-insured health plan paid medical and pharmacy benefit claims.
We provide transparent insight into the dynamic mass tort/multi-district litigation space. Our sophisticated analysis outlines relevant healthcare and payer business intelligence so clients can prioritize mass tort recovery opportunities.
Outreach & Recovery Management
Through HIPAA-compliant and compassionate direct outreach campaigns, our patient advocates help individuals understand their individual recovery rights and the ways Allēus can assist in pursuing these rights. When we identify individuals through our litigation matching program who are already pursing a claim, we gather sufficient information to file a medical lien to protect our clients’ right to recover associated UCC charges and/or amounts related to the claims paid by an employer-sponsored self-insured health plan.
Backed by the resources of our affiliate, Plexos Group, a full-service business consulting, program management, and third-party administration firm, we efficiently navigate analytics, outreach and recovery of lucrative mass tort settlement while ensuring compliance with HIPAA and other applicable laws and regulations.

Pose star, Broadway icon, fashion muse, and recording artist Billy Porter is holding nothing back on 2020 in a new piece published over at Daily Beast.
Writes Porter: “So let me be clear right up front: America is not now, nor have we ever been, better than this. We have tried and, for suspended moments in time, we have succeeded. But make no mistake: This moment we are in is pure and purposeful chaos. We are a country founded on the plunder and genocide of a people who were already occupying this land, and a country built on the backs of a people stolen from their homeland, shackled on ships, and brought here to be enslaved. For 250 years! Think about that for just one moment. Take that number in for real. I finally have: a quarter-millennium.”
Porter goes on to reflect on his lived experience as a Black gay man living in “this mess of America every day of my life” and on America’s unwillingness to truly reckon with it’s racist past.
“I don’t even know where to begin. I’m sick of talkin’ about it. I’m all cried out. I’m done being scared. I’m over being terrified. I’m simply filled with rage—a kind of rage that causes me to involuntarily tremble from the inside of my soul. This rage keeps me in a broken place where there is no peace. Ain’t never been no peace for me: a Black, gay man living in America.”
Further in the piece, Porter directs his ire at the entire Republican Party, saying they’ve “played Russian roulette with our lives and now the truth has been laid bare.”
“It’s become clear that to reign in absolute power has always been the plan, and the vessel to get there matters not,” writes Porter. “The GOP has been playing the long game and the rest of us got played.”
The full piece is well worth a read.

To benefit from the various incentives that Nigeria offers to foreign businesses, they must first be registered with the Nigeria Investment Promotion Commission (NIPC). This commission is a Federal Agency that oversees, coordinates, and monitors all investments in Nigeria. This article aims to clearly understand the process and NIPC registration requirements that foreign investors need to follow to register with the NIPC.
WHAT DOES NIPC DO IN NIGERIA?
According to the NIPC Act, the NIPC does the following;
(a) Co-ordinates and monitors all investment promotion activities to which the Act applies;
(b) Initiates and support measures which shall enhance the investment climate in Nigeria for both Nigerian and non-Nigerian investors;
(c) Promote investments in and outside Nigeria through effective promotional means;
(d) Collect, collate, analyze, and disseminate information about investment opportunities and sources of investment capital, and advise on request, the availability, choice, or suitability of partners in joint-venture projects;
(e) Register and keep records of all enterprises to which this Act applies;
(f) Identify specific projects and invite interested investors to participate in those projects;
(g) Initiate, organize, and participate in promotional activities, such as exhibitions, conferences, and seminars for the stimulation of investments;
(h) Maintain liaison between investors and Ministries, Government departments and agencies, institutional lenders and other authorities concerned with investments;
(i) Provide and disseminate up-to-date information on incentives available to investors;
(j) Assist incoming and existing investors by providing support services;
(k) Evaluate the impact of the Commission on investments in Nigeria and make appropriate recommendations;
(l) Advise the Federal Government on policy matters, including fiscal measures designed to promote the industrialization of Nigeria or the general development of the economy;
(m) Perform such other functions as are supplementary or incidental to attaining the objectives of the Act.
HOW DO I REGISTER WITH THE NIPC?
As stated earlier, NIPC registration is compulsory for foreign-owned companies. Additionally, local companies willing to take advantage of incentives available to businesses in Nigeria, are required to register with the NIPC. Registration comes after incorporation with the Corporate Affairs Commission.
REQUIREMENTS FOR NIPC REGISTRATION
To apply for the NIPC Business Registration Certificate, the following documents are required:
1 Duly completed Form;
2 Memorandum & Articles of Association;
3 Certificate of Incorporation;
4 CAC Form 1.1 (or CAC Forms CO2 and CO7 for old companies);
5 Power of Attorney/ Letter of Authority (where applicable);
6 Approved Remita payment receipt of processing fee (Non- refundable)
7. Payment Receipt
PROCEDURE FOR NIPC BUSINESS REGISTRATION
i. Have your organization registered with the Corporate Affairs Commission
ii. Complete the relevant application forms for NIPC registration
iii. Pay the required processing fee
iv. Submit the application alongside the required documents
v. NIPC business registration certificate is issued to the applicant
WHY DO I NEED TO REGISTER WITH THE NIPC?
a. Registration is a mandatory requirement for foreign-owned businesses
b. It positions both foreign-owned and local businesses to access business incentives within the country
c. It protects foreign-owned businesses from expropriation. In other words, the Nigerian Government would be unable to Nationalize foreign-owned businesses within the country. And even if it were to be done because of national interest, the company would be duly compensated for it.
d. NIPC registration paves the way for the repatriation of capital, profits, and dividends by foreign investors with ease
We hope we’ve been able to provide insight on NIPC registration. If you need professional services for launching your foreign-owned company as a foreign investor or need to make further inquiries concerning NIPC registration, do not hesitate to get in touch with us on the Whatsapp icon on this page or through our email address HERE, and we’ll attend to you.

Thank you for visiting the INDONESIA HP Store
Whether you’re a PC or console gamer, gaming monitors can dramatically enhance your gaming experience.
With richer colours, higher refresh rates, and generally more sophisticated image detail and fidelity, the right gaming monitor can make or break your gaming sessions. We’ve narrowed down the options to the best PC gaming monitors that you can get from HP.
But before we get into the monitors themselves, it helps to have an idea of the specs you should look for as you choose the best gaming monitor for you.
The resolution of monitors refers to the number of pixels in each dimension of the display. And the dimensions are cited as width by height (W x H). For example, a monitor listed with a resolution of 1280 x 720 means that it is 1280 pixels wide and 720 pixels high.
The larger the number of pixels in a monitor’s display means it has a higher resolution which usually equates to a better quality of display. So when it comes to gaming monitors, it makes sense that the larger monitors with higher resolutions are often sought-after.
Here are a few common resolutions of monitors, both gaming and otherwise:
Look for the highest resolution you can afford. Most dedicated gaming displays are QHD or UHD. FHD is the minimum we recommend.
A monitor’s refresh rate is the number of times per second that it updates the on-screen images, expressed in hertz (Hz). For example, a 60 Hz refresh rate means the display updates 60 times per second.
This is different from the frame rate, which measures the frequency that consecutive images appear on the screen, and is expressed in frames per second (fps). A frame refers to one single, motionless image.
The key difference between refresh rate and frame rate is that the refresh rate (Hz) is how many times the monitor is refreshing the images on the screen, while the frame rate (fps) is how many actual frames your computer is drawing each second.
While your monitor’s refresh rate (Hz) doesn’t affect the frame rate (fps) that your computer produces, if the fps is higher than the Hz, then your monitor may not be able to display all the images that your computer is actually creating.
Most monitors have a 60 Hz refresh rate. But this rate may not be fast enough for many quick-moving gaming applications, which often require 144 Hz or higher. A higher refresh rate results in a smoother picture.
A frame rate of 60 fps is an optimal amount for games. Also, look for 144 Hz in your gaming monitor.
The response time of a monitor is how fast a pixel can display a change from either black to white or from one shade of gray to another shade of gray (also called “gray to gray”). It’s measured in milliseconds (ms) as a single frame on a standard 60 Hz monitor remains on screen for just below 17 milliseconds.
The lower the response time the better. A typical response time for good gaming monitors is 5 ms or lower, with the ideal being 1 ms. Longer response times often result in ghosting, which is when you’ll see the trails that moving objects leave behind on-screen. That’s why they’re not ideal for fast-moving gaming applications.
Both refresh rates and response times should be inversely proportional for idyllic gameplay. For instance, monitors with higher refresh rates and lower response times work best for gaming applications.
And if your monitor has a high refresh rate, but also a high response time, the pixels won’t be able to respond fast enough; this can have an adverse effect on your gameplay and visual experience.
Look for 5 ms or lower.
Within monitor specs, you’ll probably notice a term called “brightness.” This refers to the monitor’s brightness, also called “luminance,” which is the amount of light that is emitted from a particular area.
The standardized measurement unit is expressed in candela per square meter (cd/m2). Typical monitor “brightness” displays range anywhere from 100 to 350 cd/m2. To put those measurements into perspective, one single candle emits light with approximately 1 candela (or cd) of luminous intensity.
Too much brightness can cause eyestrain, not enough means you’ll lose the ability to distinguish enemies in the shadows.
Since brightness in monitors is adjustable, you simply need to make sure it falls within an acceptable range for your gaming style and where you play - from a bright sunlit room to a dark basement.
100 to 250 cd/m2 is fine. More doesn’t hurt.
Another term within specs that you’ll come across is the contrast ratio. This term refers to the difference between the brightest colours (or whites) to that of the darkest colours (or blacks) that the monitor can produce.
It’s expressed in a ratio format, and most monitors have a contrast ratio of approximately 1,000:1 on average. Also, specs often separate the contrast ratio into two distinctions: static and dynamic.
Having the right amount of brightness for certain areas on the screen can be really important for making darker areas look appropriately dark, but without losing crucial details and for the best visibility in bright areas.
1,000:1 or better.
You’ll see the term DisplayPort listed in the specs of all the monitors. The DisplayPort (DP) is the Video Electronics Standards Association (VESA)-standardized digital display interface that’s used to connect a video source to a monitor. It’s also used to carry other types of data device input including USB, audio, and more.
The audio and video interface for transmitting data from monitors to controllers is called High-Definition Multimedia Interface (HDMI), which is the digital replacement for analogue video standards. Good gaming monitors offer one dedicated HDMI input to plug in PCs or consoles to the monitors.
All of the monitors on our list feature at least one HDMI input, and some offer two. Having two HDMI inputs gives you more connectivity options for expanding your current (or future) setup, such as dual monitors.
If your monitor has at least one HDMI connection then you’re good to go, since both Xbox One and PS4 consoles use these connectors.
And since many monitors have more than one HDMI in addition to other connectors, you can also connect other devices and peripherals.
One of the best computer monitors for gaming, the HP OMEN 25-inch gaming monitor offers a crystal-clear 22-inch screen with an FHD (1920 x 1080) resolution. While it’s not the largest-sized monitor, it does offer considerable clarity with a brightness measurement of 400 cd/m².
And it’s truly made for gaming with an incredibly fast refresh rate of 144 Hz and a 1 ms lightning-fast response time to reduce input lag on your game.
This monitor boasts AMD FreeSync™ technology, which is high-calibre adaptive synchronization technology that ensures your monitor and graphics card refresh simultaneously. This dramatically reduces display errors and glitches of all types, like screen tearing, input lag, and stutters. So your HP OMEN 25 display can provide smooth, crystal-clear visuals.
Enjoy convenient connection options for your entire game setup. This display has one DisplayPort, two HDMI ports, and two USB 3.0 ports. It’s even got a convenient hook for your headset.

Jump in and immerse yourself fully into your triple-A (AAA) game. Because you’re able to see more, including the corners of the screen, you’ll be able to sense any imminent threats to engage and react faster.
With an 8-bit VA (AMVA+) panel that provides a higher contrast ratio of 2,500:1 static and 10,000,000:1 dynamic, you’ll be able to see your game with clarity. A 100 Hz refresh rate and 4 ms response time give you smooth, responsive visuals that won’t stutter or interrupt your gameplay.
A variable overdrive eliminates ghosting by predicting the next frame and adjusting the LCD overdrive’s parameters. At the same time, NVIDIA G-SYNC™ technology seamlessly links your graphics card and display.
You’ll also be able to play for prolonged periods – and outlast your opponent – thanks to a comfortable, height-adjustable screen. You can tilt and swivel the display to your ideal height with a range of -5 to +23 degrees.
The wrapped display reduces distortion by directing light to your eye rather than to the side of your head. And in dark rooms, ambient lighting diffuses your display’s brightness and reduces eye strain.
The HP OMEN 32-inch gaming monitor offers a seriously large 32-inch screen for incredible viewing power. Built for gaming, the massive, crystal-clear QHD (2560 x 1440) resolution panel offers extreme detail with 77% more pixels than standard FHD displays.
