Chemical enhanced hydrocarbon recovery using isomerized c9-11 ethoxylated alcohols
A recently granted patent (Publication Number: US11920084B1) discloses a chemical enhanced hydrocarbon recovery method involving the introduction of a specialized composition into a subterranean formation through a wellbore. The composition includes a surfactant component comprising a mixture of isomerized C9-11 ethoxylated alcohols, with specific percentages of different ethoxylated alcohols. The method aims to enhance hydrocarbon recovery by allowing the composition to settle, absorb, disperse, or imbibe in the formation, resulting in the production of hydrocarbon products with varying compositions.
Furthermore, the patent details additional components that can be included in the enhanced hydrocarbon recovery composition, such as anionic disulfonate surfactants, biocide components, alkali components, cosolvent components, hydrotrope components, and viscosifying components. These components are present in specific ranges to optimize the effectiveness of the composition in recovering hydrocarbons from both conventional and unconventional subterranean formations. The patent highlights the importance of the surfactant component, particularly the mixture of isomerized C9-11 ethoxylated alcohols, in achieving the desired results. Overall, the disclosed method offers a comprehensive approach to chemical enhanced hydrocarbon recovery, potentially improving the efficiency of hydrocarbon extraction processes in various geological settings.
