Concentrated liquid surfactant composition for oil and gas operations
The granted patent (Publication Number: US11884879B2) discloses a concentrated liquid surfactant composition comprising a surfactant package, a co-solvent, and a liquid polymer (LP) composition. The surfactant composition includes an alkyl aryl sulfonate surfactant and has a total water content ranging from 0.5% to 20% by weight. The concentration of the surfactant package, co-solvent, and liquid polymer composition is carefully balanced to achieve optimal performance. The weight ratio of the total additive concentration to the total polymer concentration is at least 1:1, ensuring effectiveness.
Furthermore, the patent details specific ratios and components within the surfactant composition, such as the presence of primary surfactants, secondary co-surfactants, and the inclusion of anionic surfactants with various functional groups. The co-solvent used in the composition is selected from a range of compounds like alcohols, polyalkylene glycols, and ethoxylated phenols. The LP composition includes synthetic polymers like polyacrylamide and copolymers with specific additives for stability. The concentration of these components is critical, with the surfactant package, LP composition, and co-solvent carefully balanced to ensure the desired properties of the concentrated liquid surfactant composition.
