OREANDA-NEWS. June 29, 2010. Tethys Petroleum Limited ("Tethys" or the "Company")(TSX:TPL) announced the initial results from the AKD02 (Doris) appraisal well on the Akkulka Block in Kazakhstan, reported the press-centre of KASE.

Based on the interpretation of wireline logs and core data, oil has been encountered in the Jurassic carbonate sequence that proved productive in the AKD01 (Doris) discovery well drilled approximately 4 km to the south-east.

The lower Cretaceous sand interval in this well appears however to be water bearing probably due to faulting between the two wells. Work is now underway on preparing for a flow test on the carbonate interval following which it is planned to sidetrack the AKD02 well to the south-east with the aim of encountering the upper reservoir potentially within the oil bearing-zone.
