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 method of preparing and using a drag-reducing composition in a well treatment operation includes the step of preparing the drag-reducing composition by mixing a polymer emulsion that includes a first surfactant and a first solvent, with a second surfactant and a second solvent. The method continues with the step of combining the drag-reducing composition with an aqueous treatment fluid. The method further includes the step of injecting the drag-reducing composition and aqueous treatment fluid into a subterranean formation, a pipeline or a gathering line.

Abstract: A drag-reducing additive includes 40-85% by weight of a polymer emulsion that includes a polymer, a first surfactant, and a first solvent; 10-35% by weight of a second surfactant with an HLB greater than 8; and 5-30% by weight of a second solvent. In a preferred embodiment, the second solvent includes a terpene. In another preferred embodiment, the polymer is a copolymer that includes acrylamide and acrylic acid.

Abstract: Disclosed is a process for preparing a foamer composition having an anionic surfactant and a neutralizing amine. The process includes the steps of estimating an extent to which the anionic surfactant will decompose into acidic components under an elevated temperature range, determining an effective amount of neutralizing amine needed to sufficiently neutralize the acidic components upon the decomposition of the anionic surfactant and mixing the effective amount of neutralizing amine with the anionic surfactant. Also disclosed is a foamer composition having from about 5% to about 70% by weight anionic surfactant, from about 1% to about 20% by weight neutralizing amine, from about 2% to about 10% by weight amine-based corrosion inhibitor, from about 0% to about 20% by weight solvent, from about 1% to about 10% by weight scale inhibitor and from about 0% to about 30% water.
