** Subsidiary PECHORNIPINEFT’, OOO Lukoil Komi, Russia Received May 14, 2005 Abstract — Monitoring data on the contamination by sulfate-reducing bacteria (SRB) of the pay beds of the Usinsk, Vozei, and Khar’yaga oil fields (OOO Lukoil Komi) and the corrosion state of oil-field equipment are presented. It was experimentally found that SRB affect the rate and character of the corrosion of carbon and low-allowed steels. The formulations Olazol T2P and T2PM were tested as corrosion inhibitors and bactericides in H2S-containing mineralized aqueous and two-phase media. The experience of their commercial application was generalized.
