Ukrnafta is using the results of 3D seismic surveying to improve the accuracy of geological decisions and drilling efficiency.
“The total survey area over the past two years amounts to 1,211 km²: 582 km² in 2024 (including Ukraine’s first wireless seismic survey) and 629 km² in 2025. The work was carried out at nine fields and two blocks,” noted Bohdan Kukura, Chairman of the Board of JSC “Ukrnafta.” “The data obtained has already been integrated into geological models and drilling programs. I thank the team for their systematic work and the high-quality implementation of modern technologies in geological exploration.”
Based on the results of the completed stages of processing and interpreting data from 3D seismic surveys at three fields and one prospect area:
• geological models have been refined, and new promising areas and blocks for drilling new wells have been identified;
• based on the updated geological-hydrodynamic model, the locations of new planned wells at one of the fields were adjusted;
• one of the planned wells has already been drilled and put into operation with a high flow rate; three more wells are planned to be drilled here by the end of 2026, and two more in 2027;
• At another field, the drilling of an exploratory well has been planned.
This approach allows decisions to be made based on more accurate data, reduces geological risks, and increases the efficiency of investments in production.

The company is implementing a comprehensive program to resume operations and modernize the format of gas stations in its network. Since February 2023, it has been issuing its own fuel vouchers and “NAFTACard” cards, which are sold to legal entities and individuals through Ukrnafta-Postach LLC.
The largest shareholder of Ukrnafta is Naftogaz of Ukraine with a stake of 50% + 1 share.
In November 2022, the Supreme Commander-in-Chief of the Armed Forces of Ukraine decided to transfer to the state the share of corporate rights in the company that belonged to private owners, which is now managed by the Ministry of Defense.
JSC “Ukrnafta” and JSC “Ukrgazvydobuvannya” have jointly completed the drilling of a gas well at one of Ukrnafta’s fields.
The project, implemented as part of the cooperation between the two Naftogaz Group companies, marked the first practical step in developing internal cooperation to increase natural gas production in Ukraine.
As part of the project:
• JSC “Ukrgazvydobuvannya” provided drilling services using its own drilling rig;
• JSC “Ukrnafta” is responsible for the further development and operation of the facility.
The actual depth of the well is 5,681 meters.
“Increasing our own gas production is one of our key priorities. Synergy within the Naftogaz Group allows us to use resources more efficiently and accelerate project implementation,” said Serhiy Koretskyi, Head of the Naftogaz Group.
“This is the first joint project between Ukrnafta and Ukrgazvydobuvannya. We have developed a model of cooperation between the companies and achieved a practical result that provides a foundation for scaling up such cooperation in the future,” said Bohdan Kukura, Chairman of the Board of JSC Ukrnafta.
“Ukrgazvydobuvannya’s provision of services for the efficient use of the drilling rig fleet to increase hydrocarbon production for the state is a strategically important area of development. It strengthens Ukraine’s energy security and establishes a new model of successful cooperation within the Naftogaz Group,” emphasized Yuriy Tkachuk, CEO of JSC “Ukrgazvydobuvannya.”
The well development phase is currently underway. The drilling rig will be used to drill subsequent wells at Ukrnafta’s fields.

According to the results of 2025, JSC Ukrnafta drilled 25 new wells and increased oil and gas production in oil equivalent by 3.39% compared to 2024.
“New drilling, intensification, and other measures taken collectively enabled Ukrnafta to increase its production in 2025 by 3.39% in oil equivalent compared to 2024. In particular, oil production increased by 3.77%, and gas production by 2.86%,” the company said in a press release on Tuesday.
In 2025, the company drilled 25 new wells, which was 150% more than in 2024, when 10 wells were drilled, and became a record figure in recent years.
“Seven of these wells were drilled by the company’s own forces, which indicates the growth of internal production capabilities,” the company added.
According to Ukrnafta, drilling volumes began to grow steadily after the company came under state control. Until 2023, the pace of new drilling remained minimal, averaging one to two wells per year.
“In fact, in 2025, the same number of wells were built as in the entire period from 2015 to 2022. At the same time, the volume of drilling by the company’s own forces is also growing,” the company said.
In particular, 6,188 m were drilled in 2023, 11,082 m (+79%) in 2024, and 18,994 m (+71%) in 2025.
“We are increasing drilling within the limits of existing special permits and at the same time restoring our own drilling capacities. This allows us to systematically increase the volume of work and reduce dependence on external contractors,” said Bogdan Kukura, Chairman of the Board of JSC Ukrnafta.
It is noted that a separate focus of attention for Ukrnafta is to increase the efficiency of well construction.
“The approach to the construction of drilling sites and access roads has been updated; we are continuing to replace outdated logistics equipment. As a result, the time required for installation and dismantling work has been reduced by 24% — to 10 days of savings on the construction of one well — and the amount of equipment used has been reduced,” the company stated.

Ukrburgaz Drilling Department (a division of Ukrgasvydobuvannya JSC) drilled 40,059 meters in April 2024, which is 24% higher than the previous monthly record set in November-2023 – 32,423 meters.
“Despite the war, we continue to drill new wells, increase gas production, fill underground storage facilities and generally work on increasing production figures,” Naftogaz Group head Oleksiy Chernyshov said, quoted on the company’s website on Wednesday.
According to him, the record figures were achieved, in particular, due to the rapid construction of drilling sites, accelerated work on mobilization of equipment and installation of drilling rigs, as well as clear distribution of special-purpose vehicles to accelerate the start of drilling of 9 wells.
In turn, as the head of Ukrgasvydobuvannya, Oleg Tolmachev, commented, the acceleration of drilling is directly related to improved production performance.
“We have already significantly increased the penetration rate. This year we plan to drill 365 thousand meters,” he noted.
Naftogaz Group increased gas production by 12% year-on-year in the first quarter of 2024.
PJSC Ukrnafta is drilling a new exploration well in western Ukraine, the company’s CEO Sergiy Koretskyy wrote on his Facebook page.
According to him, the total depth of the new directional well is 2,213 meters, and more than 1,000 meters have already been drilled. The work is being carried out with the company’s own rig, which was used to drill the previous well in the same region.
The facility should provide access to two productive horizons. According to the digital 3D geological and hydrodynamic model of the field, the deeper horizon contains 464 thousand tons of recoverable reserves. The shallower horizon has 1.121 million tons of reserves.
“Thus, when we reach the resource at a deeper horizon and when production volumes decline, we can go back higher and give the well a second life with a workover. Such an approach will help the company to use the existing technological resource more efficiently,” Koretsky said.
As reported, Ukrnafta intends to drill nine new wells in 2023 and 30 in 2024. The company’s strategic goal is to double its oil and natural gas production to 3 million tons and 2 billion cubic meters by 2027, respectively. According to the latest forecast, oil production in 2023 is expected to increase by 4% to 1.405 mln tons.
“Ukrnafta is Ukraine’s largest oil producer and operator of a national network of 537 filling stations, of which 456 are in operation.
Ukrnafta’s largest shareholder is Naftogaz of Ukraine with a 50%+1 share. On November 5, 2022, the Supreme Commander-in-Chief of the Armed Forces of Ukraine decided to transfer the corporate rights of the company owned by private owners, which is now managed by the Ministry of Defense, to the state.
