Ukrgazvydobuvannia drills new well at Komyshnianske field with daily flow rate of 165,000 cubic meters of gas
KYIV. Sept 15 (Interfax-Ukraine) – JSC Ukrgazvydobuvannia has drilled a new exploration well 6,200 m deep at the Komyshnianske field (Poltava region) with a daily flow rate of 165,000 cubic meters of gas.
According to the company’s press service, the well construction was carried out based on the results of a 3D seismic survey, thanks to which it was possible to detail the geological structure of the field.
After drilling, geophysical studies were carried out in the well and a number of promising oil and gas reservoirs were identified. During the testing of a new horizon, which had not previously been discovered by any of the drilled wells, commercial gas inflow reached 200,000 cubic meters per day.
The company noted that this object increases the 2P reserves of the field (according to the international SPE PRMS classification) and opens up new horizons for increasing production by further compaction of the well grid. Drilling work was performed by Ukrburgaz with a Chinese rig manufactured in 2018.
"The Komyshnianske field is one of the assets that provides the country with gas today and has proven prospects for the future. In 2020-2021, we launched several successful superdeep production wells at the field, including one of them was fractured at a depth of 6,000 m. These wells have already provided about 3 billion cubic meters of gas," Oleksandr Romaniuk, Director of the Naftogaz Exploration and Production Division, said.
According to him, Naftogaz is also continuing exploratory drilling to unlock the potential of the northern and northeastern sections of the Komyshnianske field.
"Difficult geology and significant depths are the challenges that our team of geologists, developers and technicians have been able to overcome," he said.
The company said that the Komyshnianske field is an example of working with hydrocarbon deposits at significant depths, which are one of the company’s strategic directions. The company’s portfolio includes a number of fields with significant potential for increasing gas reserves at a depth of 5,500 m. By intensifying geological research and prospecting and exploration drilling, the company plans to boost over 30 billion cubic meters of gas reserves at these facilities.
The Komyshnianske gas condensate field was discovered in 1984 and commissioned in 1995. In 2018, 3D seismic surveys were carried out at the field. Oilfield services company Schlumberger deals with the processing and interpretation of the received data.
