US-based Epsilon Development has reported another gas discovery on one of its five blocks in Uzbekistan as the company continues its exploration push that was curtailed last year due to the Covid-19 pandemic and restrictions.
The company said that, following the drilling the first wildcat into the previously untapped highly pressured Nuroltin structure, the well flowed at a rate of mor than 1 million cubic metres per day of gas.
The Nuroltin structure is located within the Kultak-Kamashi block, which covers about 4000 square kilometres in southwestern Uzbekistan.
Three additional exploration wells are now planned to be drilled to a sub-surface depth below 3000 metres in an effort to update geological model of the discovery and estimate its reserves.
The discovery well has been converted into a producer to start generating cashflow for the company.
The successful well is located less than two kilometres from the operational gas trunkline network and produced gas will be sold on the domestic market, Epsilon said.
The well's flow rate has improved to about 1.4 MMcmd following connection to the pipeline network, the company added.
Besides the Nuroltin structure, the Kultak-Kamashi block is home to 14 other gas structures, six of which have been discovered since the beginning of 2019 when the Uzbek authorities awarded the tract to Epsilon.
The operator has estimated the block's proven gas reserves at 83 billion cubic metres, and said that it may hold additional possible reserves of about 100 Bcm.
Almost 50 prospective untapped structures have been identified on the block because of 3D seismic that now covers about 75% of the Kultak-Kamashi total licence area.
Epsilon, which is also reworking abandoned idle wells on the block, added it has been able to restore commercial flows of gas from three wells during October that together added production of about 370,000 cubic metres per day of gas.
The four other blocks under Epsilon’s control in Uzbekistan are Surkhan, Mubarek, West Fergana and Koskuduk-Ashibulak.
The company’s oil and gas projects are implemented under an investment agreement with Uzbekistan, with extracted hydrocarbons shared 50:50 with the state.
