Abstract: Polyethers having molecular weights of about 1000 to about 75,000 modified with alpha-olefin oxides having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in aqueous systems. About 1 to about 20 percent by weight based upon the weight of the polyether is required, the proportion of alpha-olefin oxide modifier varying inversely with the molecular weight of the polyether. Modified polyethers, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The modified polyether thickening agents of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

Abstract: Acetal-coupled non-ionic surfactants are easily degraded into relatively environmentally inoccuous fragments having little or no surface activity. The fragments are sufficiently low in molecular weight to be oxidized when exposed to water and atmospheric oxygen. The surface activity can also be destroyed by lowering the alkalinity of the medium in which the non-ionic surfactant is utilized to below pH 7. The non-ionic surfactants of the invention unexpectedly have very low viscosities as compared to surfactants containing a comparable molecular weight and oxyalkylene residue content.

Abstract: Gas production wells, which no longer produce gas utilizing conventional primary and secondary means of recovery, can be returned to production by treatment comprising addition of an aqueous solution of certain phosphate ester surfactants followed by successive treatment with water. Increased production also can be obtained in low-producing gas wells by similar treatment with certain phosphate ester surfactants. Subsequent to treatment of a producer well, said phosphate ester surfactant aqueous solution is forced into the formation utilizing water and said surfactant and water mixture is allowed to remain in the producing well, for an effective period of time ranging from not less than 24 hours to one month. Thereafter, conventional fluid drive means are then utilized to recover gas from the subterranean gas formation.
