A well treatment additive includes a siloxane surfactant, a solvent and an aqueous phase. The solvent is preferably a terpene hydrocarbon. Also disclosed is a method for using the well treatment additive to form and enhance the properties of terpene solvent based additives useful for the treatment of oil and gas wells. Methods of using the novel well treatment additives include using the additives in a variety of well treatment processes including, but not limited to, acidizing operations, hydraulic fracturing operations, well remediation operations and water removal operations.

Siloxane surfactant additives for oil and gas applications

A well treatment composition designed for the simultaneous enhancement of the production of both liquid and gaseous hydrocarbons from the same reservoir on a non-selective basis. The well treatment composition includes a first surfactant and a second surfactant, wherein the second surfactant is selected from the group consisting of ethylenediaminealkoxylate, diethylenetriaminealkoxylate, ethoxylated alkylene amines, ethoxylated alkyl amines, propoxylated alkylene amines, propoxylated alkyl amines, ethoxylated-propoxylated alkylene amines and ethoxylated-propoxylated alkyl amines. The well treatment composition also includes a first solvent, a second solvent and water. Methods for using the well treatment composition include the steps of emplacing the well treatment composition into wells having high and low gas-to-oil ratios.

Compositions and methods for enhancement of production of liquid and gaseous hydrocarbons

A method begins with the step of preparing a drag-reducing additive by mixing a dispersion polymer with a surfactant and a solvent. The method continues with the step of forming a drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid. The method further involves the step of injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line.

A well treatment composition is well-designed for the simultaneous enhancement of the production of both liquid and gaseous hydrocarbons from the same reservoir on a non-selective basis. The well treatment composition includes a first surfactant and a second surfactant, wherein the second surfactant is selected from the group consisting of ethoxylated alkylene amines, ethoxylated alkyl amines, propoxylated alkylene amines, propoxylated alkyl amines, ethoxylated-propoxylated alkylene amines and ethoxylated-propoxylated alkyl amines.

Methods for using the well treatment composition include the steps of emplacing the well treatment composition into wells having high and low gas-to-oil ratios.

A method of preparing a drag-reducing composition that includes a dispersion polymer includes steps for preparing the dispersion polymer, steps for incorporating the dispersion polymer into a drag-reducing composition, and steps for using the drag-reducing composition. The step of preparing a dispersion polymer includes preparing an aqueous mixture by adding a water-soluble salt and at least one polymeric dispersant to water and polymerizing one or more water-soluble monomers in the aqueous mixture. Once the dispersion polymer has been combined with the drag-reducing additive, the combination is injected into a subterranean formation, a pipeline or a gathering line.

Method of preparing and using drag-reducing dispersion polymer compositions

Methods and compositions comprising an emulsion or a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives.

Methods and compositions for use in oil and/or gas wells

A method of preparing and using a drag-reducing composition in a well treatment operation includes the step of preparing the drag-reducing composition by mixing a polymer emulsion that includes a first surfactant and a first solvent, with a second surfactant and a second solvent. The method continues with the step of combining the drag-reducing composition with an aqueous treatment fluid. The method further includes the step of injecting the drag-reducing composition and aqueous treatment fluid into a subterranean formation, a pipeline or a gathering line.

Drag-reducing copolymer compositions

A drag-reducing additive includes 40-85% by weight of a polymer emulsion that includes a polymer, a first surfactant, and a first solvent; 10-35% by weight of a second surfactant with an HLB greater than 8; and 5-30% by weight of a second solvent. In a preferred embodiment, the second solvent includes a terpene. In another preferred embodiment, the polymer is a copolymer that includes acrylamide and acrylic acid.
