JSC Ukrgazvydobuvannia launched a well at a depleted field in the Carpathians with a daily flow rate of 200,000 cubic meters of natural gas, CEO of NJSC Naftogaz Ukrainy Oleksiy Chernyshov said on Facebook.
“Recently, a well was put into operation at what was thought to be a depleted field in the Carpathians. The depleted field broke a 20-year production record in the entire region and produced more than 200,000 cubic meters of gas per day,” he wrote.
“No happy coincidence. The well is the result of coordinated work, the use of 3D seismic surveys and modern drilling technologies,” Chernyshov added.
JSC Ukrgazvydobuvannia has completed the drilling of several new wells since the beginning of 2023 and put into operation the necessary infrastructure at one of the new fields, which allows an additional 1.2 million cubic meters of gas to be produced per day, the company said in a press release.
According to acting general director of Ukrgazvydobuvannia Oleh Tolmachev, after confirming the presence of significant gas reserves at the new field, the company developed a program for its intensive development.
“We have drilled new wells and equipped the necessary infrastructure, which now allows us to produce a significant amount of blue fuel and transport it to the gas transportation system of Ukraine. This is another component of our plan to increase the production of our own fuel for the needs of the country,” he noted.
More than 250 workers from all 11 structural divisions of Ukrgazvydobuvannia and about 80 units of special equipment are involved in the implementation of the gas production project.
As reported, the company has a goal of increasing natural gas production by 1 billion cubic meters in 2023 – up to 13.5 billion cubic meters. In 2022, it produced 12.5 billion cubic meters of natural gas (commercial), which is 3% less than in 2021.
NJSC Naftogaz Ukrainy owns 100% of the shares of Ukrgazvydobuvannia.
JSC Ukrgazvydobuvannia has resumed the work of two previously stopped wells in Poltava region with a production capacity of 250,000 cubic meters per day, the company said in the Telegram channel on Monday.
“Specialists of Ukrgazvydobuvannia resumed the life of two wells that had previously stopped producing gas due to the depletion of gas-bearing horizons. Now, after an overhaul, we are extracting about 250,000 cubic meters of gas per day from them,” it informed.
As the company explained, in order to resume the work of wells, the specialists of Ukrgazvydobuvannia decided to use other promising horizons, for which they replaced old worn-out pipes and perforated them.
Both workover operations were performed by the internal service contractor UGV-Service.
“Despite the danger and difficulties with logistics and the provision of necessary materials, the employees of the branch continue to perform both basic repairs and highly complex operations to remove emergency equipment, prepare for hydraulic fracturing operations and test wells after development and exploratory drilling,” Ukrgazvydobuvannia said.
Thanks to an overhaul at one of the mentioned wells, an opportunity has also opened up to increase gas reserves that were not previously taken into account.
As reported, in January-June 2022 Ukrgazvydobuvannia reduced the supply of commercial gas by 1.5% compared to the same period in 2021, to 6.31 billion cubic meters.
A comprehensive gas treatment unit (GTU) of JSC Ukrgazvydobuvannia in Luhansk region has been damaged by mortar shelling, the company’s press service said on Monday.
The odorization unit, operator’s room, a service vehicle and a garage were damaged, it said.
There were no casualties or injuries. The personnel, namely, a driver and an operator, left the GTU.
The gas supply to the village of Lobacheve, Luhansk district, was cut off due to damage to the gas treatment unit’s equipment.
JSC Ukrgazvydobuvannia has increased production at the Kehychivske field (Kharkiv region) thanks to the drilling of directional production wells that allow reaching promising gas deposits under difficult surface conditions, the press service of the company has said.
According to the press service, the company has drilled and put into operation three wells in this field in 2021, in particular, the latter, thanks to modern technologies and rapid penetration, was drilled and connected to the surface infrastructure system ahead of schedule. Now, it operates with a flow rate of about 80,000 cubic meters per day.
“Our specialists are planning further development of the field, because despite its depletion, it is promising – residual reserves reach 5.6 billion cubic meters of gas,” the company said.
At present, at the Kehychivske field, over the entire period of operation, 22.7 billion cubic meters of gas have been produced, 41 wells are in operation.
JSC Ukrgazvydobuvannia begins to use a new technology for Ukraine’s basin analysis and modeling of hydrocarbon systems for prospecting and exploration of hydrocarbons, the company’s communications department said.
“Basin modeling is another step towards reducing risks, primarily drilling. Thanks to this technology, we will be able to improve the accuracy of risk assessment both for individual promising objects and for large geological structures in order to increase the resource base and production of Naftogaz,” Director of the Naftogaz Exploration and Production Division Oleksandr Romaniuk said, whose words are quoted in a press release on Thursday.
The company explained that based on the analysis of spatial dynamic 4D models of hydrocarbon systems, the company will predict risks, calculate the cost of projects and make decisions on production plans, in particular, drilling new wells.
The company plans to use basin analysis to assess the oil and gas potential of the Black Sea areas, prospect for hydrocarbons in the Carpathian fold belt and additional exploration of licensed areas in the Dnipro-Donetsk basin, the report says.
In UkrNDIGas, a research division of Naftogaz, the new direction is headed by Felipe Rodriguez, who has over 20 years of experience in the basin analysis industry and has worked on the development of oil and gas deposits in a number of countries, in particular, in BP, Repsol and Cepsa companies.
As the company said, the technology of basin modeling is actively used by the leading international oil and gas companies ExxonMobil, Shell, BP for forecasting and planning exploration and development processes.
