At the end of March, the Drilling innovation's specialists carried out 2 difficult operations on window cutting through two casings at the Ozernoye field.

Hydraulic KLEN-HA type whipstocks, manufactured by Drilling innovation LLC, were set in a 168mm casing.

In both cases, we have to simultaneously cut 168,3х8,9 «Е» and 244,5х9,5 «Е» casings.

The KLEN-HA 6-5/8” whipstock was oriented by the GyroTracer Directional compact gyroscopic inclinometer.

The professionalism of our engineer-technologist and the Customer's drilling crew allowed us to ensure the drilling assembly free passage into the cut technical window through two production casings.
