This study describes the status of a 23-acre, 6-pattern steam-flood pilot in the thick (300 ft) steeply-dipping (10/sup 0/) Monarch Sand, Section 26-C, Midway-Sunset field, after 18 mo. of steam injection. The steam-flood response shows a significant increase in oil production (520 bpd) relative to cyclic stimulation response. The response is significantly affected by preferential permeability, areal confinement, and localized barriers to vertical flow. The observation well temperature profiles confirm that the low- permeability zone just above the steam-injection interval is at least a local barrier to vertical steam flow. Differences between steam-flood performance and previous simulator predictions were due to reservoir heterogeneities not accounted for in the simulator study.
