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

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

Methods for treating an oil or gas well having a wellbore by, for example, injecting an emulsion or microemulsion into the wellbore to increase formation crude oil or formation gas production by the well. Methods of selecting compositions for treating an oil or gas well having a wellbore to increase formation crude oil or formation gas production by the well.

Methods and compositions for stimulating the production of hydrocarbons from subterranean formations

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

An oxidative breaker system for use in reducing the viscosity of a polysaccharide-based or derivatized polysaccharide-based suspension includes a silicone carrier fluid, an oxidizer, and a suspension aid. The suspension aid is preferably fumed silica. The oxidizer may be selected from the group consisting of alkali metal peroxide, transition metal peroxide, persulfate compound, bromide compound, and bromate compound. In highly preferred embodiments, the oxidizer is magnesium peroxide or calcium peroxide. Alternative carrier fluids and suspension agents are also included in the art. Also disclosed is a method for breaking a polysaccharide-based suspension with the inventive oxidative breaker system.

Oxidative breakers in a silicone based suspension

Methods for treating an oil well having a wellbore. The methods involve injecting a microemulsion into the wellbore to increase formation crude oil production by the well. The microemulsion comprises water, a first type of solvent and a first type of surfactant. The microemulsion includes a continuous water phase.

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. 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.

Methods for treating an oil or gas well having a wellbore and selecting compositions for treating an oil or gas well having a wellbore.

A self-adaptive cement system includes cement, water and at least one additive that reacts or/and expands in contact with oil and gas. Several chemical products have been identified including rubber alkylstyrene, polynorbornene, resins such precrosslinked substituted vinyl acrylate copolymers and diatomaceous earth. These additives have the effect of making the cement self-healing in the event of physical failure or damage such as micro-annuli. The self healing property is produced by the contact with subterranean hydrocarbon fluids, the potential repair mechanism is thus activated if and when needed in case of start of loss of zonal isolation. In another embodiment, the expansion is deliberately induced by pumping a hydrocarbon fluid in the vicinity of the set cement.

Self adaptive cement systems

A self-healing cement system includes cement, water and at least one additive that swells in contact with water from reservoir or from formation in the case of a structural failure in the set cement to provide a physical barrier in the zone of failure. Examples of such material include particles of super-absorbent polymer. These additives have the effect of making the cement self-healing in the event of physical failure or damage such as micro-annuli. The self healing property is produced by the contact of the water itself, the potential repair mechanism is thus activated if and when needed in case of start of loss of zonal isolation. Several super-absorbent polymers have been identified such as polyacrylamide, modified crosslinked poly(meth)acrylate and non-soluble acrylic polymers.
