Ukrgasvydobuvannya JSC, a part of the Naftogaz Group, commissioned a booster compressor station in the Poltava region after its full reconstruction. The plant refurbishment will allow reducing the head pressure in the wells of the Yablunivske, Skorobahatkivske and Komyshnianske fields. Therefore, the company continues to enhance the hydrocarbons production efficiency at the depleted fields.
The company managed to add over 100,000 cm of gas produced per day due to the launch of the new plant. According to the experts’ calculations, within the next 5 years the planned addition of commercial gas will reach 326.1 mcm, 32,700 tonnes of liquefied gas and 13,500 tonnes of condensate.
“High quality gas extraction at the depleted fields is one of our key strategic tasks. Specifically created groups of experts developing tailor-made solutions for the production optimisation are assigned to the largest assets. Given the significant maturity of our fields, these solutions can often be found in the sphere of infrastructure refurbishment. We are simultaneously working on several large projects to upgrade gas processing plants and compressor stations which should have a significant impact on the company’s performance,” said Oleg Tolmachev, Deputy Director for Production of the Naftogaz Exploration and Production Division.
The upgraded Yablunivska compressor station is equipped with two turbo compressor units СENTAUR 40 produced by Solar Turbines (USA). The design capacity of each unit is 3 mcm of gas per day. Currently, one of the units is fully employed, and the other unit is on stand-by. The construction and installation of the compressor station lasted 9 months.
The Yablunivske field has been developed since 1983 and is currently considered to be depleted. Over 60 bcm of gas were extracted from the field during its operation while the residual reserves are estimated at 30% of the initial ones.
Note that within the past 4 years the Yablunivske field managed to shift from the production decline to its increase by over 18%, or 210 mcm of gas.
