ABSTRACT:
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 production well. The process involves injecting into the formation via the injection well an aqueous solution of alkoxylated asphalts as a sacrificial agent to inhibit the deposition of surfactant and/or polymer on the reservoir matrix. Normally the process would be carried out by first injecting the alkoxylated asphalts into the formation through the injection well and following them with either a polymer or a surfactant solution.
