WELLBORE  RECONSTRUCTION  BY  SIDETRACKING IN  OJSC  “NK  “ROSNEFT”

Igor P. Zaikin – Director of drilling and supervising department;
Konstantin V. Kenpf – Head of downhole technologies department;
OJSC “NK “Rosneft”

Reworking and reconditioning of idle wells and increasing of production from marginal wells is now one of the effective methods to improve oil and gas field performance.
Over the decade of utilization of the sidetracking method in OJSC “Rosneft”, much progress has been made regarding technological solutions – from non-oriented drilling to drilling of horizontal lateral holes in production horizons that are 1 meter thick, in difficult geological conditions at the depth of up to 3200 meters, with lateral sections reaching 400 meters in

Key words: well reconstruction; well reworking; geonavigation; sidetracking; horizontal borehole.
