HYDROPHOBIC AGENT FOR TREATMENT ON BOTTOM AREA OF FORMATION Russian patent published in 2005 - IPC

Abstract RU 2244818 C2

FIELD: oil and gas production.

SUBSTANCE: bottom area of formation is treated with hydrophobic agent, in particular solution of ethylene/vinyl acetate copolymer expressed by general formula [-CH₂-CH₂-C(CH₃COO)H-CH₂-]_n, where n=7000-10000, in hydrocarbon solvent.

EFFECT: increased source of inexpensive hydrophobic agents with improved adhesion properties, intensified oil recovery due to increased depth of penetration of hydrophobic agent into formation, improved environmental conditions in development of oil formations, and reduced oil production expenses.
