FIELD: oil and gas production. SUBSTANCE: raw material is treated with 0.1-1.0% of nitric acid-iron mixture and treated material is added to untreated one in amount 0.01 to 0.5%. Invention is distinguished by that, prior to be treated, raw material is preheated to 30-100 C and kept at this temperature for 10 to 180 min, and concentration of nitric acid involved is 50-100%. EFFECT: intensified process and reduced expenses on oxidation agent. 3 cl, 1 tbl
