摘要：
Crude oil was recovered from rock structures (sandstone, dolomite) by flooding with supercrit. CO2 at 50 degrees C and 9.3 MPa under lab. conditions and studied for chem. compn. by gas chromatog. The first oil fraction contained C-6-C-15, hydrocarbons, the second one, the C-20-C-30 hydrocarbons. The heave components (asphalthenes) remained in the rock structure.
