Key words: radial drilling; acid tunneling, Eastern sector of the Orenburg oil and gas condensate field, coil tubing, BHA, increase of drainage area, coil tubing, dendric ramification.

The results of acid tunneling on carbonate reservoirs of the Orenburg region for the increase of drainage area are considered. Weaknesses of the technology are considered, ways to improve efficiency are proposed. The technology made it possible to obtain stable increments of oil production at pilot wells.
