FIELD: oil and gas production. ^ SUBSTANCE: composition contains 0.05-2.5% of hydrophobic power, 0.05-10% of ethylene/vinyl acetate copolymer, and organic solvent. Composition intensifies oil production owing to increased effective radius of formation bottom area treatment, prevention of moistening inversion effect upon fall of hydrophobic agent concentration, and, consequently, decreased volume of simultaneously produced water. ^ EFFECT: increased oil production, prolonged overhaul period, improved environmental safety, and lowered production expenses. ^ 2 tbl, 3 ex |
