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.
