The present invention provides compositions, systems and methods for demulsifying an emulsion including an aqueous phase and an organic phase by adding an effective amount of a composition comprising at least one quaternary organopolysiloxane or salt thereof to the emulsion, the composition optionally including at least one of quaternary epihalohydrin/polyamine copolymers or salts, and/or (poly)diallyldimethylammonium halides.

Demulsification compositions, systems and methods for demulsifying and separating aqueous emulsions

Fluid treatment systems and compositions are provided including (a) at least one material including (1) at least one carboxylic acid functional group and (2) at least one sulfur-containing group selected from the group consisting of sulfonyl functional groups, sulfonate functional groups and mixtures thereof; and (b) at least one scale control agent. The fluid treatment systems and compositions can be used to treat aqueous systems, for example as fracturing fluids for treating aqueous compositions found in subterranean formations. Methods for inhibiting formation and/or precipitation of calcium salts in an aqueous composition using the fluid treatment systems or compositions also are provided.

Fluid treatment systems, compositions and methods for metal ion stabilization in aqueous solutions

Fluid treatment systems and compositions are provided including (a) at least one material including (1) at least one carboxylic acid functional group and (2) at least one sulfur-containing group selected from the group consisting of sulfonyl functional groups, sulfonate functional groups and mixtures thereof; and (b) at least one friction reducing agent selected from the group consisting of guar gums, polyacrylamides, hydratable cellulosic materials, viscoelastic surfactants, and mixtures thereof. The fluid treatment systems and compositions can be used to treat aqueous systems, for example as fracturing fluids for use in fracturing subterranean formations. Methods for inhibiting formation and/or precipitation of metal oxides in an aqueous composition using the fluid treatment systems or compositions also are provided.

Fluid treatment systems, compositions and methods for metal ion stabilization in aqueous solutions and/or enhanced fluid performance

Fluid treatment systems and compositions are provided including (a) at least one material including (1) at least one carboxylic acid functional group and (2) at least one sulfur-containing group selected from the group consisting of sulfonyl functional groups, sulfonate functional groups and mixtures thereof; (b) at least one friction reducing agent selected from the group consisting of guar gums, polyacrylamides, hydratable cellulosic materials, viscoelastic surfactants, and mixtures thereof; and (c) at least one scale control agent. The fluid treatment systems and compositions can be used to treat aqueous systems, for example as fracturing fluids for treating aqueous compositions found in subterranean formations. Methods for inhibiting formation and/or precipitation of metal oxides in an aqueous composition using the fluid treatment systems or compositions also are provided.

Methods of treating flowback water from a subterranean formation penetrated by a well bore are provided, comprising: (a) providing remediated flowback water having a ferrous iron (Fe) ion concentration of less than about 100 milligrams of ferrous iron ion per liter of flowback water, a barium ion (Ba) concentration of less than about 500 milligrams of barium ion per liter of flowback water, and a calcium ion (Ca) concentration of at least about 1,000 milligrams of calcium ion per liter of remediated flowback water; and (b) treating the flowback water with: (i) at least one friction reducing agent; and (ii) at least one scale formation inhibiting agent and/or at least one iron precipitation control agent to provide treated flowback water which can be reused as fracturing fluid in a well drilling operation.

Methods of treating flowback water

A storage stable water-in-oil emulsion composition that includes 5% to 99% by weight of a water-in-oil emulsion polymer including a polymer or copolymer containing repeat units from an acrylamide monomer; 0.1% to 10% by weight of one or more inorganic microparticles; 0.5% to 90% by weight of a carrier solvent; and 0 to 90% by weight of a fluidizing agent. The compositions can be used to treat aqueous systems including paper processing, sludge dewatering and for fracturing fluids for subterranean formations.

Water-in-oil polymer emulsion containing microparticles

A method of treating a subterranean formation penetrated by a well bore including:

Method of fracturing subterranean formations utilizing emulsions comprising acrylamide copolymers

A method of treating mine drainage water including the step of adding a scale control agent to the mine drainage water and, optionally, adding an oxidizing agent to the mine drainage water and/or precipitating and settling the metals in their hydroxide form from the water. The treated water may be safely returned to the environment.
