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.
«Perfobur» — Radial drilling technology
The average increase in flowrate -
2 times
Additional increases in flow rates are from 40 to 100%

The work was carried out in the Republic of Tatarstan, the Republic of Bashkortostan, Yamalo-Nenets Autonomous Okrug
Drilled channels -
12
The work was carried out in various mining and geological conditions:
- limestone and sandstone type of reservoir;
- gas and oil deposits;
- depths from 700 to 3000 m
The largest increase in flow rate -
51 m3, 41t
The result was obtained at the well of LLC Bashneft-Dobycha.
2 14-meter channels were drilled and the acid treatment of drilled channels was carried out using the Perfobur jet nozzle
