The Effects of Combination of Steam Flooding, CO2 and Cyclic Steam Stimulation Injection Pilot Test in Heavy Oilfield in Sudan

Applications of Enhanced Oil Recovery (EOR) are highly required and needed in Sudan to keep oil supply at stable levels. ”FUL” Oilfield has shallow reservoir affected by big boundary bottom water drive with high crude viscosity. This research, through a comprehensive analysis the current producing wells, perforation intervals, CO2 temperature analysis, steam parameters optimization which using two approaches (deterministic stochastic) were analyzed, combination continues flooding, assisted cyclic stimulation pilot test sector. CMG-STARS CMOST AI simulators software was used this study. By determining recovery factor (RF) as objective function. It could conclude that: flooding even it decrease cut, but its effect increase is not considerable. Continuous best from these three methods.
