Enwell Energy has announced the results of the SV-25 well and the spudding of the SV-29 well at its Svyrydivske (SV) gas and condensate field in Ukraine.

The SV-25 well is an appraisal well, targeting the B-20, B-22 and B-23 horizons in the Visean formation. The well was spudded in July 2020 and has been drilled to a final depth of 5,320 metres. One interval, at a drilled depth of 5,184 – 5,190 metres, within the B-22 reservoirs was perforated, and initial testing was undertaken using a variety of choke sizes. The well has been hooked-up to the gas processing facilities to allow longer-term production testing to be conducted to optimise the operating parameters of the well. Currently, the well is producing at a stabilised flow rate of approximately 1.9 MMscf/d of gas and 109 bbl/d of condensate (452 boepd in aggregate). 

The SV-29 well has now been spudded and has a target depth of 5,450 metres. Drilling operations are scheduled to be completed by the end of the third quarter of 2021, and, subject to successful testing; production hook-up is scheduled during the fourth quarter of 2021. The well is primarily a development well, targeting production from the B-22 horizon, as well as appraising the B-21 and B-23 horizons, in the Visean formation.

 “We are very pleased with the results of the SV-25 well, which was drilled safely and successfully, and ahead of schedule. The robust flow rates recorded will provide a further boost to our overall production volumes. We are also looking forward to the safe and efficient drilling of the SV-29 well, which we hope will continue our success in the development of our fields,” Sergii Glazunov, Chief Executive Officer, said.
