OREANDA-NEWS. July 14, 2011. Tethys Petroleum Limited ("Tethys" or the "Company") (TSX:TPL) updated on the progress on its Kazakhstan oil exploration and appraisal activities, reported the press-centre of KASE.
                                      
Work is currently concentrating on the testing of the AKD04 (Dero) and AKD05 (Doris) appraisal wells, and on the continued drilling of the KBD01 (Kalypso) exploration well.

Following extensive flow periods and multi-rate testing the AKD05 well is currently flowing clean oil at a stable rate of approximately 520 barrels of oil per day ("bopd") from the Upper Jurassic carbonate zone. It is now planned to acidize this zone which should significantly increase production. Acidisation is planned within the next two weeks after which the well (which is already tied  into the Doris Pilot Production facilities) will be put on extended test  production.

There are potentially oil bearing sandstones in the Lower Cretaceous section of the well above the current producing zone, including a thin "Doris" sand on the edge of the interpreted Doris sand fan but these intervals will not be tested in the near future as the well is intended to carry out a extended production evaluation of the deeper Upper Jurassic carbonate zone.
