In the period from 20th to 28th February, Drilling innovation's specialists carried out window cutting operations for new Customer.

The “window” was cut in a non-standard 8 5/8" casing with inclination 89 degrees at a depth about 5000m by using hydraulic whipstock KLEN HA 8 5/8".

Due to unique design of the hydraulic anchor, the whipstock was set in the horizontal section of the well without any problems.

The whipstock was oriented by MWD system, for which a specially designed circulation valve DIV was included in to BHA.

The "window" was cut for one trip.

Setting of hydraulic whipstock without using of sement plug allowed us to leave the emergency wellbore and continue drilling.
