Cyclic CO(sub 2) injection for light oil recovery: Performance of a cost shared field test in Louisiana. Final report, November 21, 1988--November 30, 1992.

摘要

The ultimate objectives of the research were to provide a base of knowledge on the cyclic CO(sub 2) stimulation (or CO(sub 2) huff-n-puff) process for the enhanced recovery of Louisiana crude oil, and to demonstrate the utility of the process to the small independent producer. The project was divided into four subtasks: laboratory coreflood experiments, computer simulation, field testing, and technology transfer. Laboratory corefloods were performed to investigate important process parameters. Computer simulation was used to confirm and expand laboratory coreflood results. A field-test data base was constructed and analyzed to facilitate target reservoir screening and to identify successful operational practices. The laboratory coreflood results and data base evaluations were used in the design and implementation of a field test that was conducted in conjunction with the private sector. The results of laboratory and field studies were disseminated to the industry through presentations at technical conferences and publications in technical journals.
