Ukrgasvydobuvannya JSC has drilled a new exploration well with a depth of 6,200 m at the Kamyshnyanske field in the Poltava region. Daily production indicators are 165 tcm of gas.
The well was designed based on the results of 3D seismics, thanks to which it was possible to detail the geological structure of the Kamyshnyanske field. After drilling, geophysical explorations were conducted and a number of promising oil and gas reservoirs were identified. During the new reservoir test, which was not previously discovered by any other wells drilled, the commercial gas flow reached 200 tcmpd. This prospect increases the 2P reserves of the field (according to the SPE PRMS International Classification) and discovers new deposits for production enhancment by further well pattern infill. Drilling operations were performed by in-house Ukrburgaz drilling contractor with a 2018 Chinese-made rig.
"The Komyshnyanske field is one of the assets that provides the country with gas today and has proven prospects for the future. In 2020-2021, we put several successful ultra-deep wells on production at the field, including hydraulic fracturing at depth of 6,000 m. These wells have already provided about 3 bcm of gas. We are also continuing exploration drilling to unlock the potential of the northern and north-eastern sections of the Komyshnyanske field. Complex geology and significant depths are the challenges that our team of geologists, reservoir engineers and technical specialists managed to overcome," Olexander Romaniuk, Director of the Naftogaz Exploration and Production Division said.
The Komyshnyanske field is an example of deep hydrocarbon formations exploration, which is one of the company's strategic directions. Ukrgasvydobuvannya has a number of fields in the portfolio with significant potential to increase gas reserves at a depth of 5,500 m or more. We are talking about Shebelinske, Krasnokutske, Vostochno-Sementsovske, Kamyshnyanske and other fields. Due to the intensification of geological studies and exploration drilling, the company plans to increase reserves by more than 30 bcm of gas from these prospects.
Recall that in February 2021, the company put into production well # 29 of the Kamyshnyanske field in the Poltava region, which, after workover and ultra-deep hydraulic fracturing operations, produces more than 320 tcmpd.
