OREANDA-NEWS. May 25, 2010. Tethys Petroleum Limited ("Tethys" or the "Company") announced that it had commenced drilling the AKD03 (Dione) exploration well in Kazakhstan, reported the press-centre of KASE.

Tethys' ZJ70 rig "Telesto" has commenced drilling on an attractive exploration prospect which is located nearby to, and south-west of, the Doris oil discovery. This well is planned to target both the Cretasecous and Jurassic intervals where oil has been flowed in the Doris oil discovery at a combined rate in excess of over 6,800 barrels of oil per day, and also plans to target the deeper Triassic and Permo-Carboniferous intervals that were not tested in the oil discovery well and are believed to have further potential. Further exploration drilling on the Akkulka block and on large surrounding Kul-Bas block is then planned.
