Kalfoglou, G

A process for producing petroleum from subterranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a prodution well. The process involves injecting via the injection well into the formation an aqueous solution of a chrome lignoulfonate complex as a sacrificial agent to inhibit the deposition of surfactant and/or polymer on the reservoir matrix. The process may best be carried out by injecting the chrome lignosulfonate complexes into the formation through the injection well ahead of or mixed with either a polymer, a surfactant solution and/or a micellar dispersion. This mixture would then be followed by a drive fluid such as water to push the chemicals to the production well. 10 claims.
