摘要: The method of modeling fluid flow over porous blocks utilizes heat transfer and fluid flow equations and a discretization numerical method to model heat transfer rates in a square cavity containing a pair of porous blocks. Fluid flow and heat transfer are modeled within a square cavity having an inlet and an outlet formed therethrough. The inlet and outlet are positioned opposite one another along a diagonal of the square cavity. A laminar airflow is introduced at the cavity inlet while a constant heat flux is maintained in the pair of porous blocks.

摘要: The method of carbo-nitriding alumina surfaces is a process for applying a carbo-nitride coating to an alumina or alumina-based composite surface. The method involves the step of applying a phenolic resin to the alumina surface in a thin, uniform film. The resin-coated alumina surface is maintained in a controlled chamber at about 8 bar pressure at a temperature of about 175° C. for about 2 hours. The surface is then heated at about 400° C. for several hours in an argon atmosphere. This converts the phenolic resin to carbon. The carbon coated alumina surface is then scanned by a laser beam while applying nitrogen under pressure. The end result is the conversion of the alumina at the surface to aluminum carbo-nitride, the oxygen being released in the form of carbon dioxide.

摘要: A composition and method for the removal of water from a water-containing hydrocarbon stream, and a method for the production of a metal/water-soluble polymer composite are provided. The composite includes a water-soluble polymer, such as guar gum, and a metal salt, such as aluminum nitrate or copper sulfate. The ratio of the metal salt to the water-soluble polymer is in the range from about 1:1 to about 5:1 by mass. The water-soluble polymer and the metal salt form a crosslinked material. The method for producing the metal/water-soluble polymer composite includes mixing a non-crosslinked water-soluble polymer with a metal salt and water to form a paste. The paste is then dried.

摘要: Carbonates, such as chalk and limestone, are rather soft minerals and may lose at least some mechanical integrity after undergoing stimulation. For instance, carbonate minerals may experience proppant embedment or asperity weakening after fracturing or matrix acidizing. Methods for hardening a carbonate mineral may comprise: introducing an aqueous carrier fluid comprising an ammonium phosphate salt into a subterranean formation comprising a carbonate mineral, and interacting the carbonate mineral with the ammonium phosphate salt to convert at least a portion of the carbonate mineral into a hydroxyapatite mineral. The subterranean formation may exhibit an increased hardness after forming the hydroxyapatite mineral. The ammonium phosphate salt may be diammonium hydrogen phosphate in some examples.

The pyrazolopyridine derivative includes a pyridyl moiety, a first pyrazole moiety, a second pyrazole moiety, and a phenyl moiety. The first pyrazole moiety is bound to the pyridyl moiety. The second pyrazole moiety is bound to the pyridyl moiety. The phenyl moiety is bound to the pyridyl moiety. The composition can be flowed into a wellbore formed in a subterranean formation, thereby inhibiting corrosion in the wellbore.
