Enwell Energy plc (AIM: ENW), the AIM-quoted oil and gas exploration and production group, is pleased to announce an update on its hydrocarbon Reserves and Contingent Resources at its wholly owned and operated, via LLC Arkona Gas-Energy, Svystunivsko-Chervonolutske (SC) exploration licence in Ukraine.
Enwell engaged independent petroleum consultants, DeGolyer and MacNaughton, to prepare an assessment of the remaining Reserves and Contingent Resources attributable to the field as of 1 January 2021. The assesment accords with SPE/WPC/AAPG/SPEE Petroleum Resources Management System standard for classification and reporting.
Svystunivsko-Chervonolutske field is located in the Poltava region in north-eastern Ukraine, approximately 15 km east of the Company’s producing Svyrydivske (“SV”) field, and has similar characteristics to the SV field. The licence was granted in May 2017, with a duration of 20 years, and extends over an area of 97 km2 .
The licence is prospective for gas and condensate, and has been the subject of exploration since the 1980s, with five wells having been drilled on the licence since then, although none of these are currently on production. As with the productive reservoirs in the SV field, the prospective reservoirs in the licence comprise a series of gently dipping Carboniferous sandstones of Visean age inter-bedded with shales at depth between 4,600 and 6,000 metres. Geologically, the licence is located towards the middle of the Dnieper-Donets sedimentary basin which extends across the major part of north-eastern Ukraine. The vast majority of Ukrainian gas and condensate production comes from this basin.
The Report is consistent with the Company’s proposed field development plan for the licence, which includes the acquisition of 150 km2 of 3D seismic and the drilling of the SC-4 well, both activities scheduled to commence later this year, and the construction of a gas processing plant. Development will then continue with the drilling of a further six wells to recover the reserves and resources in the licence. Due to their targeted depths, the wells are each likely to take approximately 12 months to complete, and are intended to be drilled consecutively over the next eight years.
Sergii Glazunov, Enwell’s Chief Executive Officer, said: “Based on this independent assessment, a material volume of Reserves and Contingent Resources has been estimated in our SC licence. With the confidence that this independent assessment provides, we have been progressing with our field development plan to recover the reserves and resources in the licence, and based on such work, we are optimistic about the future prospects for the development of the licence.”
