On 4 May 2018, the Federal Agency for Subsoil Use held an auction for the Achi-Su block in Dagestan Republic (North Caucasus). Two local companies submitted bids and Delta-E won the contest with the offer of RUB 13.2 million (USD 0.2 million). The winner of the auction will obtain a 20-year E&P license.   Details of the offer are as follows:  The Achi-Su block covers 7.6 sq km in the Terek-Caspian Basin and encompasses the depleted Achi-Su gas/condensate field with remaining 1P reserves estimated at 9 Bcf of gas. Available seismic data amounts to 45 km. Achi-Su discovered in 1934 was producing until 2002. In 2003, a previous operator drilled well 150 to 3,112 m aimed at depletion of remaining reserves in the Upper Cretaceous reservoir penetrated at 3,078 m. During an open-hole test (3,066-3,112 m), the well flowed with gas and condensate at rates of 2.9 MMcf/d and 113 b/d through a 5-mm choke. Reservoir pressure was measured at 5,349 PSI indicating a possible separated fault block isolated from producing parts of the field. The well was suspended and it can be completed as a producer by the winner of the auction. The starting price amounted to RUB 12 million (USD 0.19 million).
