17 January 2018, the Turkmengeologiya national exploration company has tested gas with condensate in the Tagtabazar-One 16 appraisal (outpost) well. The well has flowed ca. 120 Mcm/day (4.1 MMscf/d) of gas and 13 cu m (82 bbl) of condensate from two intervals of 1,924-1,920 m and 1,951-1,942 m. The well has been drilled to a TD of 4,109 m, deeper than the original PTD of 3,779 m. Although the company does not provide further details, the intervals tested are likely to be Lower-Middle Jurassic clastics, which contain two proven reservoirs in the Tagtabazar-One gas/condensate and oil field. The field is located in the Murgab Sub-basin of the Amu-Darya Basin in southern Turkmenistan, around 20 km from the border with Afghanistan. It was discovered in 2000 by well Tagtabazar-one (Toreshikh) 1. The fieldâs two Lower-Middle Jurassic reservoirs occur at depths of 1,728 and 1,858 m. Its initial 2P reserves are estimated at 1.1 Tcf of gas and 9 MMb of oil. The discovery well was completed at a TD 2,580 m in the Triassic shales. Up to 14 more wells (nos. 2 to 15) were drilled between 2000-2004. These wells also attempted to test Triassic intervals, but no hydrocarbon flows had been recorded.
