Our interviewee tells about operations fulfilled by his company with the help of  CT units, about equipment applied and the application of achievements of commercial chemistry. O.V. Andreev also gave some details about a unique operation: with the help of screw downhole motor (ВЗД-43) specialists of the company got rid of a salt plug in tubing that couldn't be destroyed by hydraulic fragmentation. Orenburg Department on Production Enhancement and Well Workover applies CT unit M20, produced by Fidmash. It was bought in December 2002 and tried at Orenburg gas condensate field. M20 unit is used to perform such jobs as mud-and-salt plug washout in production tubing, acidizing, elimination of asphalt, resinous and paraffin deposits in production tubing, recovery enhancement by special agents in horizontal bores of oil and gas condensate wells with further fluid displacement from horizontal bores, geophysical studies of horizontal sections, development with foam systems.
