OSTI ID:6505147
A process for recovering petroleum from deposits which have already been worked by primary extraction or are not suited for primary extraction. A gas in its supercritical state is introduced into the deposit. The supercritical gas charges itself with the petroleum while flowing through the deposit. The charged supercritical gas leaves the deposit and the petroleum is separated in a plurality of fractions from the charged supercritical gas.
