FIELD: oil and gas production.
SUBSTANCE: invention relates to composition and process for improving production of oil from oil formation and cleaning oil-polluted land and surfaces. Composition contains at least 85% of fatty acid alkyl ester, surfactant, and acid. According to a process for producing crude oil, effective amount of production formulation based on the indicated composition is injected to oil formation before production of crude oil from that formation. Described are also oil-water emulsion demulsification process and oil-polluted land and surfaces cleaning. Invention is further developed in dependent claims.
EFFECT: reduced amount of residual oil in formation and improved quality of cleaning with nontoxic composition.
