FIELD: oil and gas production. SUBSTANCE: composition constitutes hydrocarbon solvent with, dissolved therein, 0.001-5 wt % of (i) product of condensation of fatty acid and mono- or diethanolamine or morpholine in molar ratio 1:1, or (ii) product of condensation of fatty acid and triethanolamine (including low-grade one) in molar ratio fatty acid/triethanolamine (1-2): 1. Advantageously, composition may be supplemented with 0.0001-1 wt % of low-molecular fatty acid. EFFECT: improved dissolving capability of composition. 2 cl |
