Petrosibir: Drilling and workover update Komi
Friday, Nov 10, 2017

We successfully completed well Sosnovskaya #35 which was spudded in September this year. The well tested 19 bopd which is similar to the initial flow rates from other wells in this field. Well #40 - the last of the current six well program - has just reached the target depth, the well will be cased and tested shortly.

In total three new wells have been fracced in the Sosnovskoye field with the following results:


Pre frac, bopd

Post frac, bopd

Current, bopd

Sosnovskaya #34




Sosnovskaya #39




Sosnovskaya #36

The logs from well #36 showed oil-saturated reservoir similar to earlier wells, however, the well did not flow any oil post frac potentially due to tighter reservoir. We are currently evaluating the option of revisiting this well to carry out a more powerful frac within the next round of fraccing.

The company plans to carry out four more fracs in the fourth quarter 2017 - first quarter 2018, depending on availability of the fraccing fleet. The upcoming fracs will include wells #33, 35, 40 and probably 36.
