Oleksiy Chernyshov: Naftogaz Group achieves yet another drilling success with two more high-rate wells

JSC Ukrgasvydobuvannya, which is part of Naftogaz Group, has launched two high-rate wells with a total flow rate of 430 tcm of gas per day.

We have recently put more high performance wells into operation in line with our goal of increasing domestic gas production. The use of the latest geological approaches, late-stage field development design, increased drilling efficiency, and complex stimulation operations have helped us give old assets a new lease of life,” commented Naftogaz CEO Oleksiy Chernyshov.

The first of the new wells is an exploration well with a depth of 5,850m. The field where it was drilled was first discovered 40 years ago. However, based on the results of 3D seismic surveys, geologists proceeded with further exploration of the field and found new prospective drilling sites.

The second well was even older, dating back 55 years. Due to significant depletion, production at this field has been declining rapidly in recent years. However, the negative trend was halted thanks to an additional drilling programme, as well as seven new production wells put into operation over the past year. This made it possible to shift from production decline to production growth,” noted Interim Director General of JSC Ukrgasvydobuvannya Oleh Tolmachev.

Company specialists put both wells into operation without outside involvement: specialists from “Ukrburgaz” carried out drilling, while UGV-Service specialists carried out the multi-stage hydraulic fracturing operation.

Background: in early July 2023, JSC Ukrgasvydobuvannya completed drilling of a new exploration well which became the deepest in the company’s history.
