Glenn Pool surfactant flood pilot test: Comparison of laboratory and observation-well data
A surfactant flood pilot test was conducted in the William Berryhill lease of the Glenn Pool field, Creek County, OK. The test was conducted in the Upper sand in a 20-acre (8.1-ha), four-inverted-five-spot pattern. The field had been waterflooded and had a residual oil saturation of 30% PV. A preflush preceded the surfactant slug, which was specifically formulated for this oil-wet reservoir. There were two observation wells in line between an injector and the central producer. Fluids from the observation well were periodically sampled and analyzed. A large oil bank observed in these wells had an oil cut of 40% or higher. Despite chromatographic separation and changing sulfonate concentration and salinity, ultralow tension was maintained for a long period. The interfacial tension (IFT) behavior involving these variables was much more complex than expected. It was concluded that the process performance in the field as monitored in the observation wells was as good as expected from laboratory linear core test results.
