Abstract: Compositions and a process for consolidating sand, proppant and other suspended particles present in a subterranean reservoir using an aqueous emulsion particle consolidation system. Surfactants with cloud points below the reservoir temperature are used to make a low viscosity aqueous external emulsion system with resin and curing agent as the internal phase. As the surfactant reaches its cloud point, it loses its emulsification ability and release the resin and curing agent to consolidate the sand. The aqueous phase of the system then functions as spacer to maintain the permeability needed for oil and gas production without additional post flush needed.

Abstract: Sulfonated betaines, amine oxides, and sultaines are made by the reaction of the corresponding unsaturated betaines, amine oxides or sultaines with a sulfonating agent. These amphoteric surfactants have demonstrated low adsorption properties in addition to good compatibility with brine containing high concentrations of salt and divalent cations. They can be employed in applications where their respective conventional amphoteric surfactants are used including: personal care, mining, improved oil recovery (IOR), oil field drilling, fracturing, acidizing, foaming, and agricultural formulations.

Abstract: A process for converting naturally occurring fats and oils to sulfonated surfactants that can be used in a variety of applications where surfactants are found to be applicable including but not restricted to Enhanced Oil Recovery, paper and pulp processing, mining, metal treating, adhesives, coatings, pesticide formulations, herbicide formulations, fungicide formulations. The byproduct of such a process is a useful solvent or source of biodiesel fuel.

Abstract: The process for making amphoteric surfactants derived from ether amine s is described. The ether amines may be derived from natural products such as animal, marine or vegetable oils or from petroleum derived raw materials. The application of these amphoteric surfactants to the recovery of residual oil by Enhanced Oil Recovery methods is disclosed.

Abstract: A composition and process for reducing the permeability of a matrix without completely blocking the matrix {is describe}. The composition uses a nano-sized water insoluble particle as a template to control the permeability by determining the size of the holes formed in the matrix.

Abstract: A method of making phenol and alkylphenol ethoxylates non-estrogenic by inserting 1 mole of propylene oxide onto the phenolic group before proceeding with the addition of ethylene oxide or mixtures of ethylene and propylene oxide. The final phenolic products can be further reacted to form sulfates, sulfonates, phosphate esters, condensed alkylphenol alkoxylates and other derivatives of alkylphenol or phenol. Non-estrogenic phenol and alkylphenol alkoxylates and their derivatives have been found to be excellent salt tolerant, high temperature stable surfactants for oil recovery from subterranean reservoirs. These products are also useful in forming emulsions of heavy crude for transportation through pipelines.

Abstract: The present invention discloses a process for producing light colored polyalkylated arylalkyl sulfonic acids. The polyalkylated arylalkyl sulfonic acids may be further neutralized with alkalis or amines to form the corresponding light colored sulfonated salts. The present invention also makes manufacture of polyalkylated arylalkyl sulfonic acids possible as first intent products using an inexpensive and simple reaction.

Abstract: An improved concentrated surfactant formulation and process for the recovery of residual oil from subterranean petroleum reservoirs, and more particularly an improved alkali surfactant flooding process which results in ultra-low interfacial tensions between the injected material and the residual oil, wherein the concentrated surfactant formulation is supplied at a concentration above, at, or, below its CMC, also providing in situ formation of surface active material formed from the reaction of naturally occurring organic acidic components with the injected alkali material which serves to increase the efficiency of oil recovery.
