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.

Majority Interest in Philippines Block SC56 Acquired by Total
Aug 23, 2012 – Total E&P Philippines B.V. announced it has agreed to a farm-out with Mitra Energy to take 75% interest in offshore Block SC56. The block is located in the Sulu Sea, covers a total area of 1,660 square miles (4,300 square kilometers) and has water depths ranging from 656 to 984 feet (200 to 3,000 meters). Mitra retains 25% interest in SC56.
A new exploration phase begins September 2012 with Mitra operating the re-processing of existing data and the acquisition of an additional 193 square miles (500 square kilometers) of 3D seismic. Operatorship will transfer to Total for drilling operations. Approval of this agreement by the authorities of the Republic of Philippines is pending.
Premier Upgrades Anoa Facility
Aug 23, 2012 – Premier Oil reported that the Anoa facility has been undergoing a series of upgrades via engineering projects collectively known as Phase 4. The first phase commenced began in July with pre-fabricated compression models being installed on the platform. The second phase of construction will continue during Summer 2013. The overall project will be completed during the second half of 2013 and will result in the development of around 200 billion cubic feet of undeveloped proven reserves on Natuna Sea Block A and increase the Anoa facility’s capacity to 200 BBtud.
Aug 23, 2012 – Construction on the Bualuang Bravo Platform is scheduled to be finished by the end of August and approvals have been received for the environmental impact assessment. The K1 HLV will begin load-out and installation of the platform by mid-October and by the end of October the platform will be ready for development drilling activities.

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 – UK’s Department of Energy and Climate Change has approved the Field Development Plan for the Fionn Field. Previously drilled and suspended, 211/22a-6, will be completed with dual electrical submersible pumps. First oil is anticipated in mid-2013 at an initial rate of 4,500 bopd. The well, which was originally drilled in 2007, tested oil from the Ness and Etive formations at a combined flow rate of approximately 5,500 bopd. Production from Fionn will be combined with production from Causeway and transported for processing to the Cormorant North platform.

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 23, 2012 – Upon completion of operations at Tomintoul, Total will move the West Phoenix (UDW semisub) to its Spinnaker prospect. Spinnaker is located West of Shetlands on Block 206/04a.

Aug 17, 2012 – Statoil has made an oil discovery at the Geitungen prospect, reported Det norske, a partner in Production License 265. Oil was encountered and a core sample was recovered. Drilling operations are ongoing and the final results from the well are not yet available, Det norske said in a statement. The Ocean Vanguard (mid-water semisub) is drilling exploratory well 16/2-12 to a total depth of 6,759 feet (2,060 meters) to prove the presence of oil-bearing Jurassic sandstones similar to the Johan Sverdrup discovery. Statoil operates the field with a 40 percent stake; while Lundin holds 10 percent; Petoro holds 30 percent; and Det norske holds the remaining 20 percent.

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.

Aug 23, 2012 – Borders & Southern received positive results from the fluid analysis performed on samples from Well 61/17-1 located offshore the Falkland Islands. The initial condensate yield from the Darwin gas samples, as measured in a laboratory separator test, varies from 123 to 140 stb/MMscf. The API gravity of the condensate is 46 to 49 degrees. Based on the condensate yield and ongoing reservoir modeling, the Company estimates the recoverable volume of condensate to be 130 to 250 million barrels with a mid-case of 190 million barrels. The company will now move forward with the acquisition of additional 3D seismic data in 2013 and explore the best way to fund an exploration and appraisal campaign.

Ophir Energy Successfully Appraises Fortuna Discovery
Aug 23, 2012 – Ophir Energy has successfully drilled the Fortuna East-1 appraisal well in Block R offshore Equatorial Guinea. Fortuna East-1 is located approximately 4 miles (7 kilometers) east southeast of Fortuna-1. The well encountered natural gas in the eastern lobe of the Fortuna Complex as well as in a deeper exploration target Viscata. The recoverable mean resource from the eastern lobe is now estimated at 426 Bcf. A 180-foot (55-meter) gas bearing column containing a total of 131 feet (40 meters) of net pay in the primary target Late Miocene sands of the eastern lobe of the Fortuna Complex was encountered. Pressure measurements indicate communication between Fortuna-1 and Fortuna East-1.
Aug 20, 2012 – Interests in two major natural gas projects in Australia have changed hands between Royal Dutch Shell and Chevron Corporation. Shell has agreed to swap its interest 33.3-percent interest in two gas fields associated with its Wheatstone project located in Western Australia and pay $450 million in cash to Chevron. In return, Shell will receive a combined interest of 36.7-percent interest in the Browse LNG project.
Shell will now hold a 35-percent ownership in West Browse and 25-percent in East Browse. International Director for Shell Upstream, Andy Brown believes this deal with simplify the ownership of the Browse gas fields.

Aug 17, 2012 – Karoon Gas has completed repair work on a blowout preventer after more than two months, and the contracted semisub rig, Transocean Legend (mid-water semisub), can resume drilling in the Greater Poseidon area in the Browse Basin offshore Western Australia. The operator is planning to drill at the Boreas-1 well, the first of a minimum five exploration wells the consortium will drill in the Greater Poseidon area, will begin on Aug. 17. All of the five exploration wells will be drilled by the Transocean Legend, and lie in the WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries. Karoon Gas holds a 40 percent stake in WA-315-P and WA-398-P, and a 90 percent stake in WA-314-P. ConocoPhillips holds the remaining stakes in the three permits.
