Feasibility Study of Improved Oil Recovery through Water flooding In Sudanese Oil Field (Case Study)

Abstract

Water flood is a mean of maintaining the reservoir pressure. It improves the sweep efficiency for oil and accordingly increases the recovery factor. Aradaiba formation in Fula North suffering from reservoir pressure which indicates that the water flooding as pressure maintenance is more suitable recovery mechanism to improve the recovery factor from this field. In this thesis selection of the suitable pilot area, converting of Eclipse model to CMG and then designing of waterflooding using the CMG and several scenarios has been done to select the optimum method to increase the oil recovery of Fula north field. The results show that Water injection as 5- spot pattern (inverted) with injection rate of 1500 bbl in Fula North field sector model can increase the cumulative oil production from this area up to6 million barrels.
