摘要： Embodiments of the present disclosure include a wellbore servicing fluid that includes a diluent, a hydrophobically modified polymer, and a base. The base provides the wellbore servicing fluid with a pH of greater than 10. The presence of the base in the wellbore servicing fluid helps to minimize changes in the viscosity of the wellbore servicing fluid when a deposit, or a kick, of salt is encountered during the drilling operation.

Preferably the anionically- and hydrophobically-modified hydroxyethyl cellulose has an ethylene oxide molar substitution of from 0.5 to 3.5, a hydrophobe degree of substitution of from 0.001 to 0.025, an anionic degree of substitution of from 0.001 to 1, and a weight-average molecular weight of from 100,000 to 4,000,000 Daltons and the dispersant is sulfonated polymer, melamine formaldehyde condensate, a naphthalene formaldehyde condensate, a branched or non-branched polycarboxylate polymer. Preferably, the aqueous cementing composition is pumped downwardly into said casing, pumping upwardly into the annulus surrounding said casing until said aqueous composition fills that portion of the annular space desired to be sealed, and then maintaining said aqueous cementing composition in place until the cement sets.

摘要： Embodiments of the present disclosure include performing one or more oil recovery cycles that recovers oil from an oil containing reservoir. The one or more oil recovery cycles can include providing a flow of supercritical carbon dioxide to the oil containing reservoir, injecting a flow of a surfactant to the flow of supercritical carbon dioxide, where the supercritical carbon dioxide and the surfactant form a mixture, forming an emulsion of the mixture in water within the oil containing reservoir to control mobility of the supercritical carbon dioxide in the oil containing reservoir, reducing the flow of the surfactant to a reduced flow while maintaining the flow of the supercritical carbon dioxide to the oil containing reservoir, and recovering the oil displaced from the oil containing reservoir.

摘要： Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.
