Improved efficiency of miscible CO{sub 2} floods and enhanced prospects for CO{sub 2} flooding heterogeneous reservoirs. Quarterly technical progress report, April 1, 1995--June 30, 1995
The objective of this experimental research is to improve the effectiveness of CO{sub 2} flooding in heterogeneous reservoirs. Activities are being conducted in three closely related areas: (1) exploring further the applicability of selective mobility reduction (SMR) in the use of foam flooding, (2) exploring the possibility of higher economic viability of floods at slightly reduced CO{sub 2} injection pressures, and (3) taking advantage of gravitational forces during low interfacial tension (IFT), CO{sub 2} flooding in tight, vertically fractured reservoirs. Progress made this quarter in the following tasks is described: Task 1 CO{sub 2}-foams for selective mobility reduction; task 2 reduction of the amount of CO{sub 2} required in CO{sub 2} flooding; and Task 3 low IFT processes and gas injection in fractured reservoirs.
