Seismic Survey Completed on RWE Dea’s Block 23 Offshore Turkmenistan

Aug 20, 2012 – RWE Dea has completed its 3D seismic survey offshore Turkmenistan in under four months. Approximately 154 square miles (400 square kilometers) was acquired in RWE Dea’s Block 23, which was awarded as part of a production sharing contract (PSC) in 2009.
According to RWE Dea, it will take several months for geologists and geophysicists to interpret the processed data collected from the Miocene and Pilocene rock strata at depths of 9,842 to 21,325 feet (3,000 to 6,500 meters). This 3D seismic survey transitioned from onshore to shallow water and was the first of its kind conducted on the coast of Turkmenistan. An additional 2D program was included in the seismic measurements in order to further assess the exploration potential of the area.

Premier Reaches TD on Chim Sao NW Appraisal Well

Aug 17, 2012 – Premier Oil reported that the Chim Sao North West appraisal well, CS-3X, has reached a total depth of 13,894 feet (4,235 meters). The well has been plugged and abandoned after encountering oil shows in the Middle Dua sands. The appraisal well was drilled to determine whether the Chim Sao North West discovery extended into a separate fault segment to the north. The well targeted the Upper and Middle Dua sands. While 443 feet (135 meters) of sandstone reservoir were penetrated in the Upper Dua interval there was no indication of hydrocarbons. In the Middle Dua interval 541 feet (165 meters) of sands were drilled, but only oil shows were encountered. The CS-N17XP well, which was completed immediately prior to the appraisal well, was drilled to produce from the North West extension to the Chim Sao Field. That well was brought on-stream earlier this month with initial extended production test rates averaging 4,000 barrels of oil per day from four Upper Dua reservoirs.
