A process incorporating integrated units and combined cycle energy production is provided for the recovery and upgrading of oil containing deposits which are not readily amenable to recovery and upgrading, to produce therefrom a light oil and elemental sulphur. Residual hydrocarbons generated in the process are gasified to produce hot gases which are used as a source of energy for process use, including electric power. The electric power is utilized to electrolyze water and produce hydrogen for use in upgrading and oxygen for use in gasification. The integration of gasification of residual hydrocarbons to produce, inter alia, electric power with the electrolysis of water to produce hydrogen for upgrading, and efficient use, distribution and recovery of energy in combined energy cycles provides an economical and essentially energy sufficient process with the flexibility to be adapted for the recovery and upgrading of various low yield oil deposits.

A process for the recovery and upgrading of oil containing deposits such as heavy oil, tar sands, shale and coal, which once initiated is essentially energy sufficient, said process comprising the steps of: (a) recovering the deposit; (b) treating the deposit to obtain a feedstock; (c) desulphurizing the feedstock with hydrogen and recovering therefrom a light oil, elemental sulphur and a heavy residual oil; (d) electrolyzing water to produce hydrogen and oxygen, said hydrogen being utilized in step (c); (e) gasifying said heavy residual oil in a series of gasifiers using air-oxygen mixtures to produce hot gases, wherein the concentration of air and oxygen may vary from gasifier to gasifier, the oxygen being supplied from step (d); and (f) utilizing said gasifier hot gases to provide energy for use in the process.
