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.

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.

Aug 23, 2012 – Statoil, along with its partner Petoro, has announced plans for further development of the Gullfaks South field located on the Norwegian continental shelf. Production in the field has fallen sharply in recent years. With a planned investment of $1.4 billion, Statoil will apply its “fast-track” concept which will make use of existing infrastructure as well as two new subsea structures and six additional development wells. The partners believe that their investment will allow recovery in the field to be increased by 65 million barrels of oil equivalent.

Aug 17, 2012 – Talisman Energy stated that the Duart field, which was shut-in on July 26 due to a process shutdown on the host Tartan platform, remains shut-in to date. During the shut-in period, additional technical issues have come to light which are preventing the restart of gas processing on the Tartan platform. The gas process is required to support Duart production. The operator will continue to close the field until these problems are resolved. Talisman indicates that the earliest restart date is December 2012.

The multi-component seismic company Reservoir Exploration Technology ASA (RXT) has entered into a LOI with an international oil company regarding acquisition of 4C seismic data in West Africa. The intention is to conclude the final contract during May and start up of the project will be in Q2.
The work is estimated to take 4-5 months, depending on the final lay out of the acquisition design. The final contract is subject to board and government approvals.
Reservoir Exploration Technology ASA (RXT) is the only marine geophysical company specializing in multi component seismic seafloor acquisition.
Multi-component seismic solves several imaging challenges that cannot be resolved with towed streamer seismic, and targets improved oil recovery from existing fields. The technology also gives better data quality for appraisal and development, and is also the solution where towed streamers are impractical due to high density of platforms and/ or shallow waters. The Company has offices in Oslo, Norway in Rio de Janeiro, Brazil in Abu Dhabi, UAE and Houston, Texas.
