On the request of our partners, for solving the accident issue at the Beregovoe oil field we promptly prepared a set of equipment: the whipstock with hydraulic anchor type KLEN HA – 6 5/8.

Drilling crew had been trying to cope with the accident in the well for more than two weeks. The only and right decision to bring the well to the planned bottom hole was sidetracking with One-trip Whipstock setting.

One-trip hydraulic Whipstock KLEN НА 6-5/8’’ was set up at 7970ft depth. The window was cut out in 4 hours.

Inspection of the reaming mills with gauge ring showed no loss in diameter. The orientation of Whipstock was carried out by engineers of Drilling Innovation LLC.
