摘要
The invention concerns an enhanced oil recovery process improving the gas sweeping of an oil formation reservoir comprising at least one injection, through at least one injection well, either simultaneously or separately, of a plug of solution, preferably aqueous, of at least one surfactant and of a gas and/or steam plug (or "slug"), so as to form a foam. At least a portion of said reservoir is swept by said foam and the hydrocarbons are recovered through at least one producing well. The surfactant complies with the general formula RF-Y-X wherein RF is a perfluoric carbon radical, Y is a single bond or a divalent carbon radical containing at least one oxygen, sulfur and/or nitrogen atom, and X is a hydrophilic group.
