A distillation residuum bottoms composition and other alternative amine compositions are used as clay inhibitors in water-based drilling fluids and in hydraulic fracturing fluids for drilling wells and for fracturing subterranean formations, and are also used as clay inhibitors in other treatment fluids for treating wells or subterranean formations.

Clay inhibitors for drilling, fracturing, and other procedures

A method of enhanced oil recovery wherein: (a) a flooding composition is delivered into a subterranean reservoir; (b) the flooding composition includes a sulfur surfactant; and (c) the fluid produced from the subterranean reservoir can also be analyzed to determine if the surfactant is present in the fluid. The surfactant preferably includes a sulfonate moiety or other sulfur-containing moiety. The presence of the surfactant in the fluid produced from the subterranean reservoir is preferably determined by X-ray fluorescence spectroscopy, HPLC-AES, or HPLC-ICP.

Compounds and method for enhanced oil recovery using sulfur surfactants

The invention relates to a hydrocarbon recovery composition comprising an anionic surfactant, wherein said composition is in the solid state, and to a shaped article comprising said composition. Preferably, said composition is in the form of a powder. Further, the invention relates to a process for treating a hydrocarbon containing formation comprising the steps of a) transporting said composition or shaped article to the location of the hydrocarbon containing formation; b) dissolving said composition or shaped article in water thereby forming an aqueous fluid containing the hydrocarbon recovery composition; c) providing the aqueous fluid containing the hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation; and d) allowing the hydrocarbon recovery composition to interact with the hydrocarbons in the hydrocarbon containing formation.

Composition and method for enhanced hydrocarbon recovery

A hydrocarbon recovery composition which comprises a first blend of C24-28 internal olefin sulfonates and an injectable fluid composition comprising the hydrocarbon recovery composition, water and/or brine wherein the hydrocarbon recovery composition is present in an amount of from 0.05 to 1.0 wt % of the total injectable fluid composition can be used for enhanced hydrocarbon recovery from a formation.

Composition for enhanced hydrocarbon recovery from a formation

A method of treating a formation containing crude oil with specific solubility groups and chemical families is described. The method includes (a) providing a hydrocarbon recovery composition to at least a portion of a formation containing crude oil with specific solubility groups and chemical families, wherein the composition comprises a Cinternal olefin sulfonate; and (b) allowing the composition to interact with hydrocarbons in the crude oil containing formation.

A drilling fluid comprising a pyruvate-free xanthan, which may be an acetate-free pyruvate-free xanthan, and a high density calcium-based brine. Preferably the pyruvate-free xanthan is a genetically prepared pyruvate-free xanthan. A process for recovering crude oil from an oil-bearing subterranean formation by drilling the formation and using a drilling fluid comprising a pyruvate-free gum and a high density calcium-based brine.
