1 August 2018, Turkmennebit national oil trust is continuing appraisal drilling at the Altyguyi field onshore western Turkmenistan. Well Altyguyi 34 has been drilled to a TD of 4,100 m. A test at a depth of 4,060 m has flowed unspecified volume of oil.  Although no further details have been provided, it could be assumed, by analogy with well Altyguyi 22, that the successful test comes from the Lower Red Beds, the main play in the Turkmen part of the South Caspian Basin.  The Altyguyi discovery is located south-west of the Korpeje oil field in Western Turkmenistan. Turkmennebit (Turkmenneft) discovered Altyguyi in December 2008 with the Altyguyi 1 wildcat. The wellâs first successful test flowed oil from the interval of 3,670-3,680 in the Lower Red Bed Series (Pliocene) at a rate of 100 t/d (ca. 750 bo/d). A second test discovered gas in the interval of 3,616-3,625 also in the Lower Red Beds. The gas flowed at 15.4 MMscf/d.  Background Information  In April 2010, Turkmennebit reported a flow of oil and gas in the appraisal well Altyguyi 4. The well had tested 75 t oil/day (ca. 560 bo/d) and 100,000 cu m/day (3.4 MMscf/d) gas from a reservoir at 3,700 m.   In late October 2014, well Altyguyi 14 tested a flow of oil in excess of 100 tonnes/day (750 b/d) from a depth of 3,800 m in the Lower Red Bed Series. The company did not provide any further details of the test/well.   In March 2014, Turkmennebit tested oil in the appraisal well Altyguyi 22. The well had been drilled to a TD of 4,100 m. It was tested between 4,012-4,018 m in the Lower Red Bed Series and flowed oil. No further details were reported.
