A nonproducing CO/sub 2/ flood tertiary recovery test was recently completed in the Willard Unit of Wasson field. Flood responses during waterflood and alternate injection of CO/sub 2/ and water were monitored at a logging observation well using compensated neutron and pulsed neutron logs. A pressure core was taken to measure residual oil saturations at the test conclusion. The overall objective of the testing was to obtain information for evaluating the potential for full-scale CO/sub 2/ flooding in the unit. The method for making this evaluation involves (1) defining CO/sub 2/ flood displacement efficiency and representing this efficiency in a miscible flood reservoir simulator; (2) defining a representative average reservoir description; and (3) projecting full-scale CO/sub 2/ flood performance with the simulator. The study provides a status report on progress to assess CO/sub 2/ flooding potential for the Willard Unit in this manner. (18 refs.)
