... CuO nanoparticles concentration to reduce viscosity are clarified in SAGD process. Laboratory tests were conducted in three experiments through the use of 2 dimensional scaled SAGD cell from an Iranian heavy oil reservoir. In the first and second experiments, the SAGD cell were saturated by heavy oil...

... Abstract Steam assisted steam drainage (SAGD) or steam and gas push (SAGP) is commercially utilized to recover bitumen from oil sands. It produces higher oil rate and ultimate recovery than the other thermal recovery methods. But for thin heavy oil reservoirs, the recovery is lower resulting...

... Abstract The Objective of this study is to experimentally investigate the performance of dense (liquid and super-critical) CO2 injection as an Enhanced Oil Recovery (EOR) method for extra-heavy oil reservoirs. Since CO2 is not expected to develop miscibility with heavy crude oil, CO2 injection...
