A method and apparatus for desalinating water combined with power generation, wherein a desalination system is used for desalinating aquifer brine water and is operationally related to a power generation system, wherein such dual-purpose co-generation facility captures the natural gas entrained within the aquifer brine water.

Apparatus and method for potable water extraction from saline aquifers

Provided herein are compounds, compositions, and methods having application in the field of enhanced oil recovery (EOR). In particular, provided herein are co-solvents, as well as aqueous compositions comprising these co-solvents, that can be used for the recovery of a large range of crude oil compositions from reservoirs.

Alkoxylated co-solvents

Provided herein are compounds, compositions, and methods having application in the field of enhanced oil recovery (EOR). In particular, the short hydrophobe anionic surfactants as well as aqueous compositions comprising these surfactants are provided that can be used for the recovery of a large range of crude oil compositions from challenging reservoirs.

Short hydrophobe anionic surfactants

Provided herein are, inter alia, compositions including a surfactant and a phenol-alkoxylate co-solvent useful in enhanced oil recovery. The compositions and methods provided herein are particularly useful for oil recovery under a broad range of reservoir conditions (e.g. high to low temperatures, high to low salinity, highly viscous oils).

Phenol-alkoxylate co-solvent surfactant composition

Provided herein are inter alia non-surfactant aqueous compositions and methods having application in the field of enhanced oil recovery. In particular, non-surfactant compositions including light co-solvents and an alkali agent presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Light co-solvent compositions

Provided herein are inter alia novel compositions and methods having application in the field of enhanced oil recovery. In particular, the large hydrophobe compounds and mixtures thereof presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Large hydrophobe surfactants

Provided herein are inter alia novel compositions and methods having application in the field of enhanced oil recovery. In particular, the short hydrophobe compounds and mixtures thereof presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Alkyl hydrophobe surfactants

Provided herein are inter alia novel compositions and methods having application in a variety of fields including the field of enhanced oil recovery, the cleaning industry as well as groundwater remediation. In particular, the alkoxy carboxylate compounds and mixtures thereof presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Alkoxy carboxylate surfactants

The present invention includes compositions and methods for treating a hydrocarbon-bearing formation by contacting the hydrocarbon-bearing formation with a fluid that includes at least one of a polyol or polyol ether, wherein the polyol and polyol ether independently have from 2 to 25 carbon atoms; and at least one of a monohydroxy alcohol, ether, or ketone, wherein the monohydroxy alcohol, ether, and ketone independently have from 1 to 4 carbon atoms, and wherein the at least one of a polyol or polyol ether is present in the fluid at at least 50 weight percent, based on the total weight of the fluid.

Method for treating a formation with a solvent

Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra-high molecular weight non-ionic surfactant.

Anionic polyalkoxy group comprising surfactants on basis of guerbet-alcohols, method of manufacture and use in enhanced oil recovery (EOR) applications

In particular, the quaternary ammonium compounds and mixtures thereof presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Quaternary ammonium surfactants

Compositions and methods for oil recovery using a surfactant-less alkaline-polymer system in hard water or hard brine is described in the instant invention. The formulation further includes a chelating agent, an alkaline agent (which can be the same as the chelating agent), and a co-solvent. The formulations as disclosed herein are capable of forming a surfactant in-situ resulting in Winsor Type III micro-emulsions of low interfacial tension.

Short chain alkylamine alkoxylate compositions

A novel idea involving the coupling of COgeological storage with methane and/or heat production (geothermal energy) from geopressured-geothermal aquifers is described herein. The production of energy from the extracted brine offsets the cost of capture, pressurization, and injection and the subsequent injection of brine containing carbon dioxide back into the aquifer. Calculations described in the present invention indicate that this offset would reduce the cost of carbon capture and sequestration (CCS) to a point that CCS could survive in a competitive market environment without subsidies or a price on carbon.
