Miscible displacement of petroleum

Patent ·
OSTI ID:5006548

A miscible displacement process for the recovery of petroleum from a petroleum bearing formation is performed in situ by use of a solvent miscible with the petroleum. The solvent has a density greater than water and is followed by an aqueous driving fluid. The process involves introducing a slug of the solvent capable of dissolving formation hydrocarbons into the upper portion of an oil reservoir and forcing the solvent through the reservoir to some lower point, the driving fluid being an aqueous fluid.
