ABSTRACT:
The production of hydrocarbons from a subterranean hydrocarbon-bearing formation is stimulated by injecting into the formation an aqueous solution of a compound hereinafter described. The elimination of plugging of capillary openings within the formation and mineral scale deposition on production equipment due to post-precipitation of dissolved salts subsequent to treatment by means of said compound results in a substantial improvement in hydrocarbon recovery.
