Results of SV-31 Well

Enwell Energy plc (AIM: ENW), the AIM-quoted oil and gas exploration and production group, is pleased to announce the results of the SV-31 well at its Svyrydivske (SV) gas and condensate field in Ukraine.

The SV-31 well is a development well, targeting production from the V-21 and V-22 horizons in the Visean formation. The well was spudded in September 2021 and has been drilled to a final depth of 5,240 metres. One interval, at a drilled depth of 5,210 - 5,219 metres, within the V-22 reservoir was perforated, and initial testing demonstrated good gas flows. The well was then hooked up to the gas processing facilities to allow production testing, using a variety of choke sizes, to be conducted to optimise the operating parameters of the well. Currently, the well is producing at a stabilised flow rate of approximately 2.65 MMscf/d of gas and 185 bbl/d of condensate (650 boepd in aggregate).

In light of the Russian military action in Ukraine, on 24 February 2022, Enwell shut-in and made safe its production and drilling operations at all of its fields. Subsequently, on 11 March 2022, having taken a number of measures to ensure safe operations, Enwell commenced the partial restart of production operations at its Mekhediviska-Golotvshinska (MEX-GOL) and SV fields, and subsequently limited field operations have been undertaken at those fields, including the completion of the SV-31 well. However, all operations remain suspended at the Vasyschevskoye (VAS) gas and condensate field and the Svystunivsko-Chervonolutskyi (SC) exploration licence.

Sergii Glazunov, Chief Executive Officer, said: "We are very pleased with the results of the SV-31 well, which was drilled safely and successfully, and ahead of schedule. The completion of the well in the current extremely challenging environment in Ukraine is a great achievement by our team, and the strong flow rates recorded will provide a welcome boost to our overall production volumes."
