Abstract: A method of enhanced oil recovery for a crude oil production well includes the steps of pyrolyzing rubber materials including the steps of heating the rubber materials to form pyro-vapors, condensing the pyro-vapors to form pyro-gas and pyro-oil where the pyro-oil includes an inhibitor solution including non-polar hydrocarbons and polar hydrocarbons. The inhibitor solution is injected as an injection stream into the crude oil production well to facilitate production of crude oil from the crude oil production well.

Abstract: Compositions may include an asphaltene dispersant that is the product of a reaction between a polysaccharide having at least two sugar subunits and one or more fatty acid reagents, and a petroleum fluid produced from a subterranean formation and containing asphaltenes therein. The asphaltene dispersant may have a molecular weight of at least 4000 Da. Compositions may further include an aromatic solvent. Methods may include contacting a hydrocarbon fluid with an asphaltene dispersant dissolved in an aromatic solvent, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents. Methods may also include contacting a hydrocarbon fluid with an asphaltene, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents and has a molecular weight of at least 4000 Da.

Abstract: The present disclosure is generally directed to an apparatus for pumping suspended polymer liquids that reduces the formation of polymeric deposits at the seal contact surfaces and filters out deposits that do form. This allows for an oil drag reducing agent (DRA) to be delivered continuously from topside through an umbilical to subsea produced fluids flowlines to increase oil production and/or flow of gas/oil by reducing friction loss due to turbulent flow in the flowlines.

Abstract: The present disclosure provides methods and compositions for controlling asphaltenes in a subterranean formation. The compositions may include a halloysite nanotube. The nanotube has a lumen and a polymer, along with a charged surfactant, may be disposed in the lumen. A wax may be disposed on the nanotube. The wax may be disposed at either or both ends of the nanotube, thereby temporarily preventing the polymer and charged surfactant from leaving the lumen.

Abstract: A process for treating a subterranean earth formation includes the step of introducing an acidizing treatment fluid comprising a monovalent salt of monochloroacetic acid into the subterranean earth formation in the presence of at least one bromide or iodide salt or salt precursor, wherein the at least one bromide or iodide salt or salt precursor is introduced into the subterranean earth formation in an amount of from about 0.3 to about 10 wt %, based on the total weight of the acidizing treatment fluid. The acidizing treatment fluid itself includes the monovalent salt of monochloroacetic acid, the at least one bromide or iodide salt or salt precursor, and optionally an element to suppress precipitation of calcium glycolate and/or at least one acid.

Abstract: Disulfide solvents may be particularly effective for dissolving deposits comprising elemental sulfur, but the extreme odor of these solvent may make their use rather problematic. Solvent blends comprising at least one disulfide solvent, amine solvent, ketone solvent, and ester solvent may afford a less obnoxious odor and not appreciably compromise the sulfur dissolution capabilities. Surfaces contacted with such solvent blends or at least partially spent variants thereof may exhibit excessive odor due to loss of one or more of the amine, ketone, or ester solvents. Excessive odor resulting from a solvent residue upon a surface may be alleviated by contacting the surface with at least one oxidant. Odor balance may also be restored to at least partially spent solvent blends by introducing additional ester solvent, which may convert a biphasic mixture into an emulsion comprising the disulfide solvent.
