JSC “Ukrnafta” has purchased and commissioned modern equipment for well logging and formation fluid analysis, which will improve the accuracy of geological and engineering decisions and reduce data acquisition time, the company announced on Tuesday.
“Developing our own research base is a strategic component of the oil and gas company’s operations,” said Bohdan Kukura, chairman of the board of Ukrnafta.
According to him, previously some of the research was carried out by external contractors, which limited the speed of analysis, but now the company has its own analytical base, thanks to which it has improved the quality of field development planning and reduced the time required to make technical decisions.
“At the same time, we are building the capacity to provide research services to other subsoil users as a separate business line,” added Kukura.
Ukrnafta, in particular, has acquired its own PVT (Pressure-Volume-Temperature) unit—laboratory equipment for studying the physical properties of reservoir fluids (oil, gas, condensate) under high-pressure and high-temperature conditions. This makes it possible to analyze the characteristics of hydrocarbons directly under reservoir conditions.
In addition, downhole pressure gauges have been purchased and are being used to measure pressure at the wellbore and along the wellbore, echo-logging dynamographs to determine fluid levels, generate dynamograms, and analyze the performance of well equipment, mini-PLT—compact logging tools, as well as samplers for the sealed collection of deep samples of water, oil, gas, or oil-gas mixtures from a specified depth.
JSC “Ukrnafta” is Ukraine’s largest oil production company, carrying out a full cycle of activities in the production sector: exploration, oil and gas production, provision of oilfield services, as well as management of the largest network of gas stations in Ukraine, UKRNAFTA.
The company has over 1,106 oil wells and 131 gas wells on its balance sheet.
By the end of 2025, Ukrnafta became the leader in the extraction industry with a turnover of UAH 99.4 billion, as reflected in Opendatabot’s Index of Top Companies.
The UKRNAFTA network is the largest network of gas stations in Ukraine, comprising nearly 700 stations and ranking among the top three in terms of fuel sales volume. The UKRNAFTA brand consolidates networks that previously operated under the Glusco, Shell, and U.Go brands.
The shareholders of JSC “Ukrnafta” are NJSC “Naftogaz of Ukraine” and the Ministry of Defense of Ukraine. Since 2022, the company has been under state management and is undergoing a large-scale business transformation.
In January-September 2025, Ukrnafta completed the drilling of 15 new wells, with another 10 currently being drilled. A total of 25 new facilities are planned to be commissioned by the end of the year, according to a press release issued by the company on Monday.
“We are maintaining production growth: +4.5% for oil and +1.7% for gas,” said Yuriy Tkachuk, acting chairman of the board of Ukrnafta.
According to the company, Ukrnafta uses 3D geological modeling, API-standard equipment, digital solutions, and artificial intelligence technologies to achieve significant results.
Over the past three years, Ukrnafta has conducted 1,330 square kilometers of 3D seismic surveys, which creates the basis for expanding the company’s resource base and helps to drill new wells more efficiently.
Ukrnafta is Ukraine’s largest oil production company and operates the national network of gas stations. In March 2024, it took over the management of Glusco’s assets and currently operates a total of 663 gas stations. It holds 92 special permits for industrial development of deposits. It has 1,832 oil and 154 gas production wells on its balance sheet.
The largest shareholder of Ukrnafta is Naftogaz of Ukraine with a 50%+1 share. In November 2022, the Supreme Commander-in-Chief of the Armed Forces of Ukraine decided to transfer the company’s corporate rights, which belonged to private owners, to the state, and they are currently managed by the Ministry of Defense.
Ukrnafta’s net profit for 2024 was UAH 16.38 billion.
Ukrgazvydobuvannya, part of the Naftogaz group, has commissioned a new high-yield exploration well with a flow rate of 383,000 cubic meters of natural gas per day.
This was reported in a press release of the group with reference to the chairman of the board of Naftogaz of Ukraine, Serhiy Koretsky.
“This result is a joint achievement of all divisions of Ukrgazvydobuvannya that were involved in the design, drilling, and development.
I would like to thank everyone who worked on this well. Step by step, we are strengthening our own production,” he said.
The well is inclined, with a depth of almost 5.7 km. All work, from drilling to commissioning, was completed a month and a half ahead of schedule.
According to Naftogaz, two more exploration wells are currently being drilled at the same field, and three more are planned to start drilling in the near future.
As reported, Ukrgazvydobuvannya set a new drilling record in January-March 2025, reaching 107,136 meters, which is almost twice as much as in the same period of 2024 and exceeds the previous quarterly maximum recorded in the third quarter of 2024 (102,866 meters).
JSC Ukrgazvydobuvannia launched a new exploration well at the Bezpalivske field in Kharkiv region with a flow rate of 160,000 cubic meters of gas per day, according to a press release from the company.
“The Bezpalivske field is relatively young. At present, the field’s reserves amount to more than 4 billion cubic meters of gas, and we continue to explore the field – we have carried out 3D seismic surveys, we are drilling exploratory wells,” Oleksandr Romaniuk, the director of the Naftogaz Exploration and Production division, said.
According to him, in 2018 Ukrgazvydobuvannia also launched a modern complex gas treatment unit and is intensifying production at already operating wells. As a result, over the past four years, the company has managed to quadruple production at this field, to 222 million cubic meters of gas in 2021.
“In 2022, we expect this positive trend to continue, the new well will contribute to this,” Romaniuk stressed.
The location for drilling a well with a depth of 5,200 meters was determined based on the results of 3D seismic surveys conducted in 2020.
The Bezpalivske field was put into pilot development in 1995. During this time, 27% of the initial gas reserves were produced at the field.
NJSC Naftogaz Ukrainy owns 100% of the shares of Ukrgazvydobuvannia.
