The hydraulic whipstock KLEN 12-3/4” for 324mm casing (12-3/4”) was produced by special order of foreign customer at first time. The equipment was shipped to the customer and it was run and set in the casing at the depth 500m.

The reason to apply such big size of whipstock was the customer’s desire to leave the emergency borehole and continue the drilling.

For window cutting in 324mm (12-3/4”) casing it was spent about 10 hours.

Once again the Drilling Innovation LLC worked reliably and customer’s requirements have been satisfied.
