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.
Ukrgazvydobuvannia in January-July 2021 reduced gross production of natural gas by 5.2% (by 437 million cubic meters) compared to the same period in 2020, to 7.932 billion cubic meters, the press service of the company said.
According to its data, gross production for the seven months decreased by 5.1% (by 406 million cubic meters) compared to January-July 2020, to 7.493 billion cubic meters.
Underfulfillment of the production plan is 125 million cubic meters and 51 million cubic meters respectively
In July 2021, gross gas production decreased by 4.8% (by 57.5 million cubic meters) compared to July 2020, to 1.144 billion cubic meters, marketable – by 4.5% (by 50.8 million cubic meters), to 1.088 billion cubic meters.
To stabilize production indicators during January-July 2021, the company commissioned 25 new wells, carried out 80 well workovers, performed 321 coiled tubing operations, 71 hydraulic fracturing operations, carried out nine sidetracking operations, equipped a remote monitoring system for 197 high-production wells.
As reported, Ukrgazvydobuvannia, 100% of which belongs to NJSC Naftogaz Ukrainy, in 2020 reduced production of marketable gas by 1.2% (by 170 million cubic meters) compared to 2019, to 13.45 billion cubic meters, and the company’s gross production amounted to 14.23 billion cubic meters.
Misen Enterprises AB (Sweden) received $47.06 million from Ukrgazvydobuvannia (UGV), a subsidiary of Naftogaz Ukrainy, in an arbitration dispute over a stake in the Joint Activity in accordance with a ruling by the Kyiv Court of Appeal made on January 5, 2021.
According to the report of Misen Energy AB (publ) on its website, another UAH 1 million was received by another company under its control – Karpatygaz LLC.
Ukrgazvydobuvannia also paid UAH 236.11 million in nonresident income tax to the state budget.
According to the report, this compensation reflects Misen Enterprises AB’s and LLC Karpatygaz’s share of the replacement costs of the equipment subject to the joint ownership under the Joint Activity agreement.
“However, this compensation does not reflect the going concern value of Misen Energy AB (publ.)’s share at the time the exorbitant subsoil use tax was imposed on the Joint Activity, which led to the termination of the Joint Activity Agreement. Misen Energy AB (publ) and its partially owned subsidiaries reserve all their rights in this respect,” Misen said.
JSC Ukrgazvydobuvannia, part of the Naftogaz Exploration and Production division, reduced the production of marketable gas by 0.5% (by 47.8 million cubic meters) in January-September 2020, as compared to the same period last year, to 10.135 billion cubic meters.
Naftogaz noted that it will be more difficult to maintain production at last year’s level in the fourth quarter due to the cumulative effect of negative factors associated with the four months’ lack of approval of the permits required to start drilling, as well as low prices for energy with a consequent reducing of investment in production activities, and a delay of the delivery of equipment and materials due to quarantine restrictions.
In general, it was possible to maintain production volumes over the nine months due to the modernization and construction of ground infrastructure facilities, the implementation of the development program and additional exploration of existing fields, as well as work on new areas.
So, since the beginning of 2020, the divisions of Naftogaz Group have completed the drilling of 27 wells, performed 210 workovers of wells, 75 hydraulic fracturing operations, and 551 coiled tubing operations, completed the reconstruction of four gas treatment units, the construction of four gas pipelines and 66.8 km of plumes.
JSC Ukrgazvydobuvannia in January-March 2020 reduced commercial gas production by 0.4% (by 13.6 million cubic meters) compared to the same period of 2019, to 3.401 billion cubic meters, which was transmitted for the needs of the population and heating companies, the press service of the company said.
Ukrgazvydobuvannia said that it was possible to maintain commercial gas production at last year’s level due to the commissioning of 14 wells, some 158 coil-tubing operations, some 30 overhaul of wells operations and some 29 hydro fracturing operations for three months.
The first deputy director general of the company, Oleksandr Romaniuk, said that the revenues of oil and gas companies will decrease due to reduced demand in the markets, followed by lower oil and gas prices, which will lead to a decrease in investments.
“In addition, due to the coronavirus [COVID-19] pandemic, contractors cannot always follow the contractual terms of work and supplies. Until the end of the year, we will feel the negative impact of these factors on production indicators,” he said.
Romaniuk also said that the recently concluded service contract between Ukrgazvydobuvannia and Expert Petroleum international company will allow involving foreign investment and management practices of the company’s depleted fields in 2020.
The company also continues to modernize its ground infrastructure, in particular it plans to re-equip existing and construct new gas processing plants. Joint projects are continuing with Schlumberger to drill well No. 888 of Shebelynka gas field and Halliburton to rehabilitate wells from an out-of-act ion stock by drilling offshoots.
