Publication number: 20250012177Abstract: Hydrogen foams may be used for placing and maintaining hydrogen in a subterranean location. For example, methods for introducing hydrogen to a subterranean location may include: placing a hydrogen foam in a subterranean location, in which the hydrogen foam comprises a continuous phase generated from a foamable composition comprising an aqueous fluid and a discontinuous phase comprising at least hydrogen gas; and maintaining the hydrogen foam in the subterranean location.Type: ApplicationFiled: July 5, 2023Publication date: January 9, 2025Applicants: SAUDI ARABIAN OIL COMPANY, ARAMCO SERVICES COMPANYInventors: Sehmus OZDEN, Ayrat GIZZATOV, Zuhair AL YOUSEF

Publication number: 20240391764Abstract: Hydrogen may be produced from natural gas (e.g., methane). For example, a method for producing hydrogen from natural gas may include: introducing natural gas to a reactor, wherein the reactor contains therein a catalyst, wherein the catalyst includes a high entropy alloy, and wherein the high entropy alloy has an entropy, S, such that S?11.31 J K?1 mol?1; reacting the natural gas with the catalyst to form hydrogen gas and solid carbon; and separating the hydrogen gas from the solid carbon to produce a hydrogen stream comprising the hydrogen gas from the reactor.Type: ApplicationFiled: May 22, 2023Publication date: November 28, 2024Applicant: SAUDI ARABIAN OIL COMPANYInventors: Sehmus OZDEN, Feng LIANG, Ashok SANTRA, Rajesh SAINI

Publication number: 20220348507Abstract: Ultra-lightweight aerogels and methods for fabricating such aerogels from ammonia borane and a support structure, where the support structure is either two-dimensional nanostructures, or hydrocarbon polymer colloids. The components are mixed, then annealed. The properties of the disclosed aerogels can be tuned by controlling the ratio between the support structure and the ammonia borane, or by infiltrating the aerogels with additives.Type: ApplicationFiled: January 20, 2021Publication date: November 3, 2022Applicants: The Trustees Princeton University, LutaiInventors: Rodney D.

Publication number: 20200362231Abstract: Gelled fluids include a gellable organic solvent, an aluminum crosslinking compound, and a mutual solvent. The gelled fluids may be prepared by combining an aluminum crosslinking compound and a first volume of a gellable organic solvent to form a pre-solvation mixture; gelling the pre-solvation mixture to form a pre-solvated gel; combining the pre-solvated gel with a formulation fluid to form a gellable mixture, the formulation fluid comprising a second volume of the gellable organic solvent; and gelling the gellable mixture to form the gelled fluid.Type: ApplicationFiled: August 3, 2020Publication date: November 19, 2020Applicant: Saudi Arabian Oil CompanyInventors: Leiming Li, Ghaithan A. Al-Muntasheri, Feng Liang, Sehmus Ozden

Patent number: 10696892Abstract: Gelled hydrocarbon fracturing fluids and their methods of preparation and use are provided. The gelled hydrocarbon fracturing fluid includes a hydrocarbon fluid, a phosphate ester, a crosslinker and a viscosifier. The crosslinker may include iron, aluminum, or combinations thereof and the viscosifier may include clay, graphite, carbon nanotubes, metallic oxide nanoparticles, and combinations thereof. The method of preparation includes combining a hydrocarbon fluid, phosphate ester, and crosslinker to form a baseline fluid. A viscosifier is added to the baseline fluid to form a gelled hydrocarbon fracturing fluid. The method of use includes treating a subterranean formation by contacting a subterranean formation with a gelled hydrocarbon fracturing fluid and generating at least one fracture in the subterranean formation.Type: GrantFiled: May 31, 2017Date of Patent: June 30, 2020Assignee: Saudi Arabian Oil CompanyInventors: Sehmus Ozden, Leiming Li, Ghaithan A.
