West Hackberry tertiary project. Summary annual report, September 3, 1996--September 2, 1997
The goal of the West Hackberry Tertiary Project is to demonstrate the technical and economic feasibility of combining air injection with the Double Displacement Process for tertiary oil recovery. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering oil through gravity drainage. The novel aspect of this project is the use of air as the injection fluid. The target reservoirs for the project are in the Oligocene Age sands located on the west and north flanks of West hackberry Field in Cameron Parish, Louisiana. If successful, this project will demonstrate that the use of air injection in the Double Displacement Process can economically recover oil in reservoirs where tertiary oil recovery is presently uneconomic. By the end of the fourth year of Budget period 1, air injection has been under way at West Hackberry since November of 1994 on the west flank and since July of 1996 on the north flank. During the past year, the most noteworthy events were: (1) increased oil production in low pressure reservoirs on the north flank, (2) demonstrated economic viability of air injection in low pressure reservoirs, (3) increased west flank reservoir pressure as a result of air injection and (4) intensified program of technology transfer activities. This report includes a discussion of the areas of progress.
