A Computational Fluid Dynamics Study of Flared Gas for Enhanced Oil Recovery Using a Micromodel

چکیده
The current handling of gas associated with oil production poses an environmental risk. This is being flared off due to the technical and economic attractiveness this option. As gases are mainly composed methane, they have harmful greenhouse effects when released into atmosphere. work discusses effectiveness using for enhanced recovery (EOR) purposes as alternative flaring. In study, a micromodel was designed properties similar sandstone rock porosity 0.4, computational fluid dynamics (CFD) techniques were applied design EOR system. Temperature not considered in simulation run at atmospheric pressure. Five case studies carried out different interfacial tensions between (0.005 N/m, 0.017 0.034 N/m) injection rates (1 × 10−3 m/s, 1 10−4 10−6 m/s). model compared laboratory experiment measuring immiscible flooding. Factors affecting recoveries, such tension gas, viscosity, pressure, studied detail. results showed that surface interphase limiting factor maximum recovery. lower recovered 33% original place. capillary pressure higher than micromodel, which lowered amount displaced. study importance maintenance increase floods. It recommended wider set be tested obtain range gas.
