Completions & stimulations through directional short radius radial bit-drilling.

Drilling is carried out along the predicted trajectory using the «Perfobur» technical system of our own design.

Technology

The «Perfobur» technology is a mechanical radial drilling with a predicted channel trajectory.

Today, «Perfobur» allows to drill radial channels up to 15 m long with a diameter of 69 mm, it is possible to create up to 4 channels within one horizon.
