1Compositional modeling and simulation of dimethyl ether (DME)-enhanced waterflood to investigate oil mobility improvement显示文摘Dimethyl ether(DME) is a widely used industrial compound, and Shell developed a chemical EOR technique called DMEenhanced waterflood(DEW). DME is applied as a miscible solvent for EOR application to enhance the performance of conventional waterflood. When DME is injected into the reservoir and contacts the oil, the first-contact miscibility process occurs, which leads to oil swelling and viscosity reduction. The reduction in oil density and viscosity improves oil mobility and reduces residual oil saturation, enhancing oil production. A numerical study based on compositional simulation has been developed to describe the phase behavior in the DEW model. An accurate compositional model is imperative because DME has a unique advantage of solubility in both oil and water. For DEW, oil recovery increased by 34% and 12% compared to conventional waterflood and CO_2 flood, respectively. Compositional modeling and simulation of the DEW process indicated the unique solubility effect of DME on EOR performance.Jinhyung Cho Tae Hong Kim Kun Sang Lee 2018Petroleum Science2018,15,2:2
