Campion, F E

A process for using surface-active agents to stimulate production from reservoirs containing interstitial water in the vicinity of the production wells is described. The process consists of treating the production wells with a mixture of anionic and nonionic surface-active agents having critical properties, and thereafter producing the injected solution and connate fluids from the formation. The use of a combination of certain water-soluble and oil- soluble alkali metal sulfosuccinates and long chain polyethylenoxyethanols in proper proportions will overcome water blocking, emulsion blocking and related difficulties due to the presence of interstitial water, and will generally permit improved production from oil-bearing zones which do not respond significantly to the treating agents utilized for stimulation purposes in the past.
