document: In the second half of 2017, Kalmtatneft completed testing of an exploratory well in Tsekertinskaya license in Kalmykia (North Caucasus). Baryernaya 1 spudded in 2015 reached its final TD 5,800 m in May 2017. Based on logging, three intervals were identified for testing. In August, the company tested gas and condensate at rates of 4.45 MMcf/d and 585 b/d through 14 mm choke from two lower intervals tested together at a depth around 5,500 m. Based on 3D seismic data and the well results, Kalmtatneft estimated 3P reserves ta 260 Bcf of gas and 12 MMbbl of condensate with possible increase to 438 Bcf and 20 MMbbl. In 2018-2019, the company plans to drill outpost Baryernaya 2 with a PTD of 5,600 m. The well was aimed at exploration of the Lower Triassic section of the Baryernyy prospect with pre-drilled resource estimates of 40 MMbbl of oil. The prospect is located in the southwestern part of the 3,530 sq km block. In 2013-2014, Kalmtatneft drilled wildcat Biryuzaksakaya Vostochnaya 1 in the same license. The well drilled to 3,397 m at the Tithonian section. No hydrocarbons were tested in open hole and the well was abandoned without setting of a production casing. Kalmtatneft is equally owned by Tatneft and Lukoil-subsidiary Ritek.
summary: Baryernaya 1 op. by Kalmtatneft (100%) in Tsekertinskaya license in Kalmykia, tested gas and condensate at rates of 4,45 MMscf/d and 585 bcond/d through 14 mm choke from two lower intervals tested together at a depth around 5 500 m, estimated 3P reserves ta 260 Bcf of gas and 12 MMbbl of condensate with possible increase to 438 Bcf and 20 MMbbl.
