20 November 2019, Epsilon Development Company obtained a high rate flow of gas from a well in the Nazarkuduk discovery in the XX Kultak-Kamashi block, Amu-Darya Basin. A flow of 1 MMcm/d (34.3 MMscf/d) was recorded in the well Nazarkuduk 2. This high flow rate was obtained as a result of fracking operations.  A similar gas flow was received from wel Nazarkuduk 4 in September 2019, also following fracking.   The Nazarkuduk field was discovered by Zeromax GmbH with well Nazarkuduk 1 in 2009. The field has one reservoir in the Callovian-Oxfordian Carbonate unit XV-XVa at a depth of ca. 3,750 m.  Epsilon sells gas from the Nazarkuduk field to the state-owned pipeline operator Uztransgaz for delivery to domestic customers.  Background Information  Zeromax spudded the Nazarkuduk 1 wildcat in the then East Kultak-North Nishan-Kamashi licence area. The well was spudded with a plan TD of 4,000 m and targeted the Callovian-Oxfordian Carbonates gas play.   Zeromax received a five-year exploration licence for the East Kultak-North Nishan-Kamashi (now XX Kultak-Kamashi) investment block in April 2008. It had originally appointed UzGazOil as the project operator, but in the middle of 2008, the operatorship was transferred to the Kultakneftgaz JV (Zeromax and UNG). Gissarneftgas, another Zeromax-UNG joint venture company, was involved in developing several fields located within the East Kultak block under a separate contract. Zeromax was announced bankrupt by the Uzbek state in 2010.  Epsilon Development LLC positions itself as a vertically integrated natural resource project development company engaged in the exploration, acquisition, development and production of oil and natural gas reserves and resources. Its primary operations are in Uzbekistan. The company claims to have rights to six investment blocks in the country, including -    XX East      Kultak-North Nishan-Kamashi and Mubarek in the Amu-Darya Basin,   XXV Surkhan in the      Afghan-Tajik Basin (Surkhandarya Depression),   XXIX West Fergana      in the Fergana Basin,   XXXV Koskudyk and      XXXVI Ashibulak in the North Ustyurt Basin.    A consortium of investors has been established in order to implement projects in Uzbekistan. It includes Thyssen Krupp (Germany), Epsilon Development Company LLC (USA) and Epsilon Asia Limited (Hong Kong).Â The consortium plans to invest up to USD 5.2 billion in all the above blocks in 2019-2023. It expects to discover 485.5 Bcm (16.6 Tcf) of gas, 12 MMt (ca. 96 MMb) of condensate and 8.6 MMt (ca. 65 MMb) of oil in the next 5 years. All production would initially be sold in the domestic market. Construction of a gas processing plant could also be considered at a later stage.
