Turkmen authorities report successful testing of well Uzynada 1 (2020) drilled in the Uzynada gas condensate discovery on the Caspian coast. The well tested 106,000 cu m of gas (3.63 MMscf/) and 143 tonnes (ca. 1,150 bbls) of condensate in January 2020. The hydrocarbons have been teseted from the Lower Red Bed Series (Pliocene), in the interval of 6,746-6,752 m.   Uzynada was discovered in May 2017 (see details in Background below) by the country's first super-deep well Uzynada 7 (TD 7,150 m). Turkmenistan had since announced plans to drill appraisal (outpost) wells Uzynada 8 and 17, however, it has not been reported if these wells have been drilled and tested.  In December 2019, it was announced that the Turkmengeologiya state exploration trust, in co-operation with Turkmennebit production company, was preparing to drill a 6,500 m deep exploration well in the Uzynada Gunorta (Uzynada South) prospect. The prospect was identified during a recent seismic survey.  Background Information  The Uzynada discovery is located close to the Caspian coast, some 30 km south of the Barsagelmes field (South Caspian Basin). It was was discovered by well no. 7 in May 2017. The well flowed gas with condensate at rates of 17.1 MMcf/d and 1,200 b/d, respectively, from the interval of 6,689-6,695 m.   The well has been drilled to 7,150 m and is the first super-deep well in Turkmenistan. It was drilled by Turkmennebit with a Chinese-made âZJ70â heavy drilling rig.   In December 2018, Turkmennebit state exploration and production trust was reported to be drilling two appraisal wells at Uzynada, nos. 8 and 17. No further details were disclosed at the time.  Â The Uzynada discovery is important for understanding prospectivity of the Block 21âs which lies immediately offshore. Four prospective intervals were identified in well 7 prior to drilling, including the Apsheronian Formation at -3,100 m subsea, the Upper Red Beds (Pliocene) at -4,000 m, and two intervals in the Lower Red Beds at -5,600 m and -6,125 m.   Seismic surveys were carried out over the Uzynada structure in 1973 and 1980. At least four exploration wells were drilled in the Uzynada structure in the 1970s, to TDs between 4,200 m and 4,400 m. None of those wells had been successful.
Turkmen authorities report successful testing of well Uzynada 1 (2020) in the Uzynada gas condensate discovery on the Caspian coast. The well tested 3,63 MMscf/d and ca. 1 150 b/d of condensate, from the Lower Red Bed Series (Pliocene), in the interval of 6746-6752 m.
