... in parallel with achieving optimum reservoir management it will result in higher capital efficiency while improving key economic metrics such as operating expenditure (Opex), reserve replacement ratio, depreciation depletion & amortization (DD&A), and overall earnings. Given the existing challenges...

... in heavy oil reservoirs, high oil viscosity results in early breakthrough and poor sweep efficiencies. Polymers have been used to increase the displacing water viscosity for conformance control and viscous fingering attenuation. However, polymer degradation and entrapment inside the reservoir make them...

... Abstract Steam assisted gravity drainage (SAGD) is recognized as a profitable and stable approach to address the exploitation of heavy oil and oil sand resources. However, the efficiency of SAGD, a close relative of a sufficiently-expanded and uniformly-developed steam chamber, tends...

... a challenge due to free gas formation upon heating. To establish equilibrium and due to local pressure gradients, this gas is pushed to the edges of the steam chamber, where temperatures are lower. The gas acts as a thermal insulator, reducing the efficiency of heat transfer between the steam and bitumen...

... Abstract Being the most popular technological framework for the heavy oil and bitumen production, the reservoir heating is mainly performed via steam injection. Progressively it becomes evident, however, that there exist other methods offering an efficient production for various initial...
