During 2019, three works were carried out at the wells of Bashneft-Dobycha LLC. All work was carried out on limestone reservoir: two works on the Kashirsko-Podolsky layer of the Arlanskoe field, one on the Bashkir layer of the Yugomashevskoe field.
At the first well, two channels of 7 m each were drilled. The well was put into operation with the parameters: Qf 3.8 m3 / day, Qo 1.5 t / day, water-cut 56%. 9 months after the start of the well, the anchor module of the Perfobur technical system allowed re-entry into the drilled channels. Acid treatment was carried out in each channel through a jet nozzle. Having successfully completed this task, the Perfobur specialists have clearly demonstrated one of their unique advantages of the technology.
In the second well, 2 channels with a length of 7 m each were also drilled. After drilling the channels and carrying out inclinometry, acid processing of the channels was carried out using the Perfobur jet nozzle. The well was put into operation with the parameters: Qf 12 m3 / day, Qo 3.9 t / day, water-cut 62%.
Two channels of 14 m each were drilled at the third well and acid treatment of the channels was carried out using the Perfobur jet nozzle - in a total volume of 48 m3 of acid. The well was put into operation with the parameters: Qf 51 m3 / day, Qo 41 t / day, water cut 11%.
