... agreement with those of the experiment for oil production rate, cumulative oil production, steam chamber and temperature contours in the model. Effects of varying several physical conditions, such as steam injection pressure, vertical separation between injection and production wells, and model thickness...

... Abstract The effect of hydrocarbon gas injection on oil production during Steam Assisted Gravity Drainage (SAGD) projects was investigated using numerical simulation. The results indicate that oil production rates as well as total oil production are significantly reduced when gas is injected...

... Abstract THAI - "Toe-to-Heel" Air Injection, is a new EOR process, which integrates advanced technology and horizontal well concepts, to achieve potentially very high recovery of heavy oil. It can also realise very substantial in situ upgrading by thermal cracking, producing upgraded oil...

... - in these thin reservoirs (5–10 m of pay) have been unsuccessful. The use of optimally placed horizontal wells in steam injection has proven economically feasible due to reduction of heat loss to the cap rock, and bottom water layer, as well as better overall heat distribution in the reservoir. Steamflooding...

... drilled from the S.E. of section 17), and the thickest porous sand. The producing well was drilled over the period of December 16, 1996, to January 7, 1997, from 3A1-17-52-23 W3M with the bottom hole lying in 4B3-16-52-23 W3M. The steam injection well was drilled over January 8, 1997, to February 3, 1997...

.... Floods were also carried out in unconsolidated cores using combinations of an alkali, surfactant and a polymer. Individual slugs were injected sequentially in some of the experiments, while the three components were mixed and injected as a single slug in other experiments. Oil recoveries in the two cases...

... fractures and cavities in hot dry rock (HDR) to produce supercritical (> 380 °C) steam at critical pressure (3,204 psi) for injection into the shallower oilbearing formations above. Employing similar techniques, the drilling system may also be used for the economical production of geothermal steam...

... wells. Fresh solvent injection (2500 m 3 /day) was initiated in 1991 to make up for significant solvent coning and changed the flood design from a vertical flood controlled by longitudinal diffusion to a horizontal flood dominated by transverse diffusion. Recycling in this case also allows the old...

... (lack of production, sand flow) prompted the state-owned operator, Albpetrol, to take remedial action in the form of cyclic in situ combustion for sand consolidation and production increase. Injection of 1200 - 3000 m ? /d/well (cum. ± 200,000 m ? /well) air resulted in a burned zone of approximately 5...

... and Southeast New Mexico, where over 1 billion scf/day of carbon dioxide is injected for enhanced oil recovery. A number of factors have come, or are coming, together to form the environment where a comparable infrastructure may be possible in Alberta. A scoping evaluation of carbon dioxide sources...

... and appraisal of the original volumes, together with recommendations as to the variation in the injection and production patterns. They were implemented accordingly but with limited success and, other than the heterogeneity of the reservoirs in the main Sergi Formation, no suitable explanation was found...

... Abstract Many heavy oil reservoirs in Turkey are not suitable candidates for thermal recovery methods, such as steam injection and in-situ combustion. The immiscible CO 2 or gas displacement process appears to be a very promising enhanced oil recovery technique for these heavy oil reservoirs...

... Abstract At the 48 th Annual Technical Meeting, one of us presented a paper that showed that there was a possibility of making the SAGD process more efficient by adding a small concentration of a non-condensible gas such as methane to steam. For this to be effective the steam injection well...

... conditions. Results of oil recovery from low permeability Spraberty cores during CO 2 injection experiments are promising. A mathematical model has been developed for scaling-up the laboratory CO 2 ternary oil recovery to pilot scale to assist pilot design. The result indicates a good potential of CO 2...

... saturations. Steam chamber ceiling propagation rates (process initialization and growth) were determined for different injection and reservoir conditions. The paper highlights critical factors that control steam-oil emulsion counter-current flow and rate of propagation of the steam chamber. In addition...

... Abstract Injection of water into reservoirs are very common in petroleum industry. For examples, produced water is disposed into deep, permeable reservoirs. In water flooding recovery process, water of huge volume is injected into reservoir to displace oil-in-place to nearby producers...

... Abstract Steam injection is used to recover bitumen from oil sand reservoirs in the Cold Lake region. The overburden contains the fluids injected, but responds to this injection by upheaval of the ground surface. The heave magnitude, distribution, and rate of dissipation away from...

... Abstract Marcy recent projects have demonstrated that the injection of steam into horizontal wells can recover significant quantities of heavy oil at economic rates. A variety of reservoir/wellbore processes have been utilized, including dual well SAGD, single well SAGD, cyclic steam...
