CASE STUDY OF NATURAL FLOW AND ARTIFICIAL LIFT FOR A SOLUTION GAS DRIVE RESERVOIR

📄 Project Abstract

Solution gas drive reservoirs are characterized by rapid and continuous decline of reservoir pressure. This rapid and continuous decline of reservoir pressure causes direct decline of reservoir performance at early stages of the life of the reservoir. The principal source of energy which is gas liberation from the crude oil and the subsequent expansion of the solution gas as the reservoir pressure is reduced are inadequate to produce such reservoirs to their full capacities. Ultimate oil recovery from natural flow of a solution - gas drive reservoir makes it one of the least efficient primary recovery mechanisms. This leaves a substantial amount of remaining oil residing in the reservoir which must be produced. Artificial lift technologies such as continuous gas lift, gas lift with velocity strings and positive displacement pumping is therefore employed at later phases of the reservoir's life to increase the ultimate recovery which is what this project sort to do.
