... injection, and steam injection. One of the advanced chemical EOR (cEOR) methods is polymer flooding, which can yield an additional oil recovery of 14% OOIP ( Sheng, 2010 ). Polymer flooding uses a high molecular-weight polymer added to the injected water as a viscosity-enhancing agent that decreases...

... and viscosity (as was injected). Others ( Surtek 2020 ) assume that polymer retention causes no delay in polymer propagation, but immediately reduces the polymer concentration and viscosity. This case is shown by the red curve in Figure 1 . This case predicts no delay in the development and movement of an oil...

... Abstract The present work clarifies the mechanisms associated with bitumen viscosity reduction during ultrasound sonication. A Canadian (CDN) and Nigerian (NGR) bitumen, selected for this study, have a respective viscosity of 2,617 and 12,043 cP at room temperature. Two series of ultrasound...
