Evaluation of recovery efficiency and injection rate of waterflooding ‘five-spot’ pattern for a sudanese oil field

Abstract

Water Flood Is A Mean Of Maintaining The Reservoir Pressure. It Improves The Sweep Efficiency For Oil And Accordingly Increases The Recovery Factor. Water flooding is very important in the oil field, therefore this research is designed to evaluate the water flooding for Heglig field in order to monitor the impact of water flooding on reservoir performance. In this research selction of suitable pilot area and designing for water flooding using the CMG.Therefore, several scenarios has been done to select the optimum method to increas the oil recovery of Heglig field. The results shows that water injection as inverted 5-spot ( 4 producer , 1 injector ) with injection rate of 1200 bbl in Heglig field sector model can increase the cumulative oil production from this area up to 1.5 million barrels.
