Oil, water and gas rates, Water: Oil Ratios, Gas: Oil Ratios and CO 2 utilization efficiency were used to evaluate treatments in production wells. Offset production wells were monitored, where possible, for production changes, sometimes seen...

... field application and valuable experience about how to design the injection parameters was provided. According to the information from laboratory experiments and the pilot test, four injection wells associated with nine offset production wells were selected for microgel treatment. For about 10 months...

... The test consisted of four production wells separated by 300 ft with a central injection well ( Figure 4 ). Several observation wells were placed between the injector and the producers. The reservoir pay consisted of a 40-ft thick sandstone capped by an 8-ft thick limestone encased as a unit...

Injection and production histories of wells in the study area were simulated, including shutdowns and the occasional conversion of production wells to steam injection wells. The framework provided by the facies groups yielded a more realistic representation...
