SOLVENT FLOODING WITH A HORIZONTAL INJECTION WELL IN GAS FLOODED RESERVOIRS

摘要

SOLVENT FLOODING WITH A HORIZONTAL INJECTION WELL IN GAS FLOODED RESERVOIRS (D#78,780-F) The invention is a method for recovering residual hydrocarbons from a reservoir which has been previously swept by gas. The invention steps comprise drilling and completing at least one horizontal injection well relatively near the top of the reservoir, injecting a miscible solvent through the horizontal injection well to create a curtain of solvent falling through the previously gas swept reservoir, and producing hydrocarbons and other fluids that have been banked below the falling solvent curtain through a production well.
