...Osaze Omoregbe; Abarasi Hart Bitumen and heavy oil are energy resources with high viscosities, high densities, and high metals and heteroatoms content. This paper reports a bibliometric survey to investigate the historic trends and the future pattern of heavy oil and bitumen recovery and upgrading...

...Olalekan Saheed Alade The viscosity of extra-heavy oils including bitumen can be reduced significantly by adding solvent such as toluene to enhance extraction, production, and transportation. Thus, prediction of viscosity and/or rheology of bitumen-solvent mixtures has become necessary. More so...

... models applying artificial neural network (ANN) to predict hydrocarbon productions under heterogeneous and unknown properties of unconventional reservoirs. We study two different thermal recovery methods—expanding solvent steam-assisted gravity drainage for bitumen and in-situ upgrading of oil shale. We...
