    • 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 via the injection well into the formation an aqueous solution of lignosulfonate salt 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 lignosulfonates into the formation through the injection well mixed with either a polymer or 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. The surfactant solution comprises a mixture of petroleum sulfonate and an alkyl benzene alkoxylated sulfonate. In another embodiment, the surfactant solution comprises sulfonated alkoxylated alkyl surfactants and/or alkyl benzene alkoxylated sulfonates.

    • Disclosed is a method for treating subterranean earth formations containing appreciable amounts of water-sensitive clays, including petroleum-containing formations, in order to render the clay content of the formation less sensitive to swelling and other phenomena which cause reductions in permeability of the earth formation when the clay content is contacted with relatively fresh water.

    • Disclosed is a surfactant fluid employing two or more surfactants, one anionic and one or more non-ionic surfactant containing two or more polyethoxy chains such as dipolyethoxylated alkylcatechols or dipolyethoxylated primary alkylamines and a process using the fluid for recovering oil from formations which also contain water having high salinities, e.g., salinities greater than about 40,000 parts per million, and which may include high concentrations of divalent ions such as calcium and/or magnesium, e.g., greater than about 3,000 parts per million calcium and magnesium. Nonionic surfactants having two or more polyethoxy chains have substantially higher cloud points than corresponding nonionic surfactants with similar oil soluble groups and the same number of ethoxy groups in a single chain. Superior results are obtained if the nonionic surfactant is chosen to have a cloud point from 20.degree. F to 80.degree. F above the formation temperature.
