Abstract: A well treatment additive includes a siloxane surfactant, a solvent and an aqueous phase. The solvent, in some embodiments, is a terpene hydrocarbon. Also disclosed is a method for using the well treatment additive to form and enhance the properties of foams useful for the treatment of oil and gas wells. Methods of using the novel well treatment foams include using the additives in a variety of well treatment processes including, but not limited to, acidizing operations, hydraulic fracturing operations, well remediation operations and water removal operations.
Abstract: A method of preparing a drag-reducing composition that includes a dispersion polymer includes steps for preparing the dispersion polymer, steps for incorporating the dispersion polymer into a drag-reducing composition, and steps for using the drag-reducing composition. The step of preparing a dispersion polymer includes preparing an aqueous mixture by adding a water-soluble salt and at least one polymeric dispersant to water and polymerizing one or more water-soluble monomers in the aqueous mixture. Once the dispersion polymer has been combined with the drag-reducing additive, the combination is injected into a subterranean formation, a pipeline or a gathering line.

Abstract: A foam generating surfactant formulation includes a betaine, an alpha-olefin sulfonate and a nanofluid. The betaine is preferably a cocamidopropyl betaine or laurel betaine. The alpha-olefin sulfonate is preferably an anionic surfactant having between 8 and 18 carbon atoms per molecule. The nanofluid is preferably an oil-in-water nanofluid that includes an emulsifying surfactant, a solvent, a co-solvent and water. The addition of the nanofluid increases the thermal stability and salt resistance of the foam generating surfactant.

Abstract: The present disclosure generally provides centrifuge container adapters configured to be used in a centrifuge, e.g., a bench-top centrifuge, and centrifuge systems and methods incorporating the centrifuge container adapters. The centrifuge container adapter may receive a centrifuge container, comprising a sample, the sample, in turn, comprising a fluid. During a centrifuging operation, according to some embodiments, the centrifuge container adapter and centrifuge container may be placed in a rotor cavity in the centrifuge. As a rotor of the centrifuge spins, the fluid may exit the sample within the centrifuge container and be collected in a void space of the centrifuge container adapter. In some embodiments, measurements of the fluid in the centrifuge container adapter may be used to determine characteristics or properties of the sample.
