Abstract: A process of making a silica-alumina composition having improved properties is provided. The process includes (a) mixing an aqueous solution of a silicon compound and an aqueous solution of an aluminum compound and an acid, while maintaining a pH of the mixed solution in a range of 1 to 3, and obtaining an acidified silica-alumina sol; (b) adding an aqueous solution of a base precipitating agent to the acidified silica-alumina sol to a final pH in a range of 5 to 8, and co-precipitating a silica-alumina slurry, wherein the base precipitating agent is selected from ammonium carbonate, ammonium bicarbonate, and any combination thereof; (c) optionally, hydrothermally aging the silica-alumina slurry to form a hydrothermally aged silica-alumina slurry; and (d) recovering a precipitate solid from the silica-alumina slurry or the hydrothermally aged silica-alumina slurry, wherein the precipitate solid comprises the silica-alumina composition.

Abstract: Disclosed are systems and methods for treating contaminated material. The material is heated by nonconductive and nonconvective heating in a vacuum chamber such that the surface of the material is heated without significant heating of the air within the chamber. The surface of the material is heated to at least a volatilization temperature of the contaminants or to a decomposition temperature of one or more compounds in intimate contact with the contaminants, so that the concentration of contaminants in the material is reduced. Exhaust is removed from the chamber and cooled. A solids and/or liquids collector removes condensed solids and/or liquids and has a gas outlet connected to a vacuum pump.

Abstract: A system for utilizing excess heat during a subsea field operation can include a subsea manifold configured to transfer a subterranean resource to a pipeline located subsea, where the subterranean resource radiates the excess heat after being transferred out of the subsea manifold. The system can also include a subsea power generation system that receives the excess heat from the subterranean resource as the subterranean resource is transferred from the subsea manifold to the pipeline, where subsea power generation system uses the excess heat to generate electrical power.

Abstract: A hybrid modeling approach incorporates both physics-based reservoir modeling and machine learning technique to capture dynamic behavior of unconventional wells. Shut-in bottom hole pressure for unconventional wells are simulated for use as proxy for reservoir pressure in unconventional reservoirs. Production parameters for unconventional wells (e.g., gas/oil ratio, water cut, flowing bottom hole pressure, shut-in bottom hole pressure, productivity index) are determined for use in controlling the operations of unconventional wells.

Abstract: A system for fracturing a plurality of wellbores on a multi-well pad includes multiple missiles, where each missile is configured to receive a high-pressure fracturing fluid from a plurality of pump trucks, where a high-pressure fracturing fluid includes substantially all components used for fracturing one or multiple wellbores. The system also includes a main manifold that receives the high-pressure fracturing fluids from the missiles, where the main manifold includes valves and output channels. The valves are operated to enable flow of the high-pressure fracturing fluids to different wellbores through the output channels to fracture the different wellbores.
