Copper Oxide Nano-fluid Stabilized by Ionic Liquid for Enhancing Thermal Conductivity of Reservoir Formation: Applicable for Thermal Enhanced Oil Recovery Processes

摘要: Since the oil reservoirs are limited and energy demand is increasing, seeking for high efficient EOR processes or enhancing efficiency of current proposed methods producing trapped from highly investigated. As a way out, it possible to couple and nanotechnology utilize both together. Regarding this possibility, in current study, first stage investigation stable uniform water-based solution nano size particles copper oxide with different concentrations (0.01-0.05 M) were prepared then injected into core samples. In stage, effects different surfactants respect their was Then, scenarios using nano-fluid as thermal conductivity modifier examined. The obtained results clearly demonstrate that changing concentration copper 0.01 M 0.05 is able enhance rocks 27 % 48 compared dry core.
