Because of high oil price and technology advancement in recent years, chemical EOR is becoming an important option for maintaining sustainable efficient development mature reservoirs the future. In this paper, integrated numerical simulation approach adopted Palouge oilfield South Sudan feasibility evaluation. The methods are preliminarily screened main oil-bearing zones, advantages disadvantages flooding analyzed by comparing technical parameter limits with parameters. Specifically, pilot zone areal position selection was determined using a comprehensive method, which based on zonal injection plan application experiences. Chemical performed sensitivity analysis different scenarios prediction. Three indicators employed to evaluate efficiency. Some key physiochemical factors uncertainty also detail, will provide unusual useful information proposed evaluation procedure provides helpful guidance assessment other analogous reservoirs.
