Abstract
The subject invention provides multi-functional biochemical compositions, as well as their use in enhancing oil recovery from an oil-bearing subterranean formation. Advantageously, the compositions and methods of the subject invention are operationally-friendly, cost-effective, and environmentally-friendly. More specifically, in preferred embodiments, the subject invention provides a multi-functional composition for enhanced oil recovery (EOR) comprising one or more surfactants, one or more chelating agents, and one or more solvents.
Claims15
A method for enhancing oil recovery from an oil-bearing formation by stimulating the flow of oil from the formation, the method comprising introducing a composition comprising one or more glycolipid biosurfactants, one or more chelating agents, one or more semi-ionic liquids, and one or more alcohols into the formation;
- wherein the one or more glycolipid biosurfactants include lactonic sophorolipids, and wherein the one or more chelating agents include ethylenediaminetetraacetic acid (EDTA).
