Patent number: 11957777Abstract: Compositions comprising a reaction product of a saccharide polymer and a fatty ester may be obtained in an aqueous phase in the presence of a hydroxide base and a neutral surfactant, the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The compositions also comprise one or more alcohols originating from the fatty ester upon forming the reaction product of the saccharide polymer and the fatty ester. The reaction product of the saccharide polymer and the fatty ester may be present in the aqueous phase at a concentration effective to lower a surface tension of the neutral surfactant. The fatty ester may comprise one or more glycerol esters, such as one or more plant and/or animal oils and/or fats, and the one or more alcohols originating from the fatty ester may comprise glycerol. Fatty acids originating from the fatty ester may be substantially straight-chain fatty acids.Type: GrantFiled: October 26, 2022Date of Patent: April 16, 2024Assignee: INTEGRITY BIO-CHEMICALS, LLCInventors: Christopher P.

Publication number: 20240076540Abstract: Compositions comprising a neutral surfactant or a reaction product thereof and a reaction product of a saccharide polymer and a fatty acid may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant), the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant. Depending on the fatty acid identity, among other factors, the compositions may promote emulsification or de-emulsification. In addition, the compositions may promote foam formation under appropriate conditions. Treatment fluids comprising the compositions, including foamed treatment fluids, may be introduced into a subterranean formation to perform a treatment operation in which fluid emulsification or de-emulsification may occur.Type: ApplicationFiled: November 9, 2023Publication date: March 7, 2024Applicant: Integrity Bio-Chemicals, LLCInventors: Christopher P.

Patent number: 11767375Abstract: Fluid contaminants may be prevalent in many industries, such as the mining industry. Functionalized saccharide polymers comprising two or more monosaccharide units linked by glycosidic bonds and having a portion of the monosaccharide units oxidatively opened and functionalized with at least one aminocarboxylic acid covalently bound through nitrogen at a site of oxidative opening may be utilized in conjunction with fluid remediation processes, such as froth flotation. In non-limiting examples, the functionalized saccharide polymers may also be useful for promoting dust control, particulate coating, clay stabilization, and various subterranean treatment operations. Glycine represents one example of an aminocarboxylic acid that may be covalently bonded through nitrogen at a site of oxidative opening.Type: GrantFiled: October 14, 2022Date of Patent: September 26, 2023Inventors: Christopher P.

Publication number: 20220389123Abstract: Amine-functionalized saccharide polymers, including oligosaccharides and polysaccharides, may be effective for promoting clay stabilization in subterranean formations. Oxidative synthesis of amine-functionalized saccharide polymers using sodium hypochlorite pentahydrate as an oxidation reagent may afford a different distribution and type of sites of oxidative opening as compared to other types of oxidation reagents. Amine-functionalized saccharide polymers may be prepared by exposing a saccharide polymer comprising a trans-vicinal diol to an oxidation reagent comprising sodium hypochlorite pentahydrate, reacting the trans-vicinal diol to form a site of oxidative opening bearing at least one aldehyde, exposing the at least one aldehyde to an amine to form an imine intermediate at the site of oxidative opening, and reducing the imine intermediate into a secondary or tertiary amine at the site of oxidative opening.Type: ApplicationFiled: July 16, 2020Publication date: December 8, 2022Applicant: INTEGRITY BIO-CHEMICALS, LLCInventors: Ashoka V.R.
