Statoil ASA , together with partners Petoro AS, Det norske oljeselskap ASA and Lundin Norway AS, has confirmed significant additional volumes in its appraisal well in the Aldous Major South discovery (PL265) in the North Sea.
The results of appraisal well 16/2-10 have increased production license PL265 estimates to between 900 million and 1.5 billion barrels of recoverable oil equivalent.
This is a doubling of the previously announced PL265 volumes of between 400 and 800 million barrels of oil equivalent.
It has previously been confirmed that there is communication between Aldous in PL265 and Avaldsnes in PL501, and that this is one large oil discovery.
“Aldous/Avaldsnes is a giant, and one of the largest finds ever on the Norwegian continental shelf. Volume estimates have now increased further because the appraisal well confirms a continuous, very good and thick reservoir in Aldous Major South,” says Tim Dodson, executive vice president for Exploration in Statoil.
Final data show that the oil column in appraisal well 16/2-10 is approximately 60 metres. These data also confirm that the reservoir is of the same, excellent quality as in the Aldous Major South discovery well 16/2-8. This is the main reason for the substantial upward revision of PL265 volumes.
The Aldous/Avaldsnes discovery extends over a large area of approximately 180 square kilometres, and there is considerable variation in both reservoir thickness and oil column height in the structure. Additional appraisal wells will be drilled in both licenses.
Statoil will await the results from these wells before providing updated and more accurate volume estimates for the combined discovery.
After completion of the appraisal well, the Transocean Leader drilling rig will move to the Troll field in the North Sea.
Aldous Major South is situated in production license PL265 in the North Sea, and appraisal well 16/2-10 was drilled 4.2 kilometres north of the 16/2-8 discovery well.
Statoil is the operator and has a 40% interest in PL265. The partners are Petoro AS (30%), Det norske oljeselskap ASA (20%) and Lundin Norway AS (10%). Well 16/2-10 is the seventh exploration well in PL265. The license was awarded in the North Sea Awards 2000.
Avaldsnes is located in production licence PL501. Lundin Norway AS is the operator with a 40% interest, while partners Statoil and Maersk have 40% and 20% interests, respectively.
Total E&P Norge AS, operator of production licence 127, has completed drilling wildcat well 6607/12-2 S. The well proved gas and oil.
Well 6607/12-2 S was drilled about eight kilometres west of the Norne field. The primary exploration target for the well was to prove petroleum in Middle and Lower Jurassic reservoir rocks (Fangst and Båt group). The secondary exploration target was to prove petroleum in Cretaceous reservoir rocks (Cromer Knoll group).
The well proved gas and oil in both the primary and secondary exploration targets with reservoir properties as expected.
Preliminary estimates of the size of the discovery are between 3 and 16 million Sm3 recoverable oil equivalents. Development of the discovery will be considered in conjunction with other fields in the area.
The well was not formation tested, but extensive data acquisition and sampling have been carried out.
This is the second exploration well in production licence 127. The licence was awarded in licensing round 10 B in 1986.
The well was drilled to a vertical depth of 4245 metres below the sea surface and terminated in early Jurassic rocks (Åre formation). The water depth is 369 metres. The well will now be temporarily plugged and abandoned.
Well 6607/12-2 S was drilled by the Songa Delta drilling facility, which will now proceed to a shipyard for its 30-year certification, before proceeding to the North Sea to drill wildcat well 25/6-4 S. Det norske oljeselskap ASA is the operator there.

September 5th, 2011, Det norske oljeselskap ASA presented a plan for development and operation (PDO) of Jette to the Minister of Petroleum and Energy, Ola Borten Moe. The PDO was submitted on behalf of the partners in the Jette Group, which in addition to Det norske as operator, includes Petoro, Dana Petroleum and Bridge Energy.
Aldous Senior Vice President Projects, Bård Atle Hovd, says this is an important step towards developing Jette.
– We have now signed the third and final contract for the development phase. As soon as we receive the Ministry´s approval, we will embark on our first field development. We wish for a fast track development, enabling us to produce oil from Q1 2013
Jette is located in blocks 25/7 and 25/8, in the mid part of the North Sea. The field, which lies at a depth of 127 meters, will be produced with two horizontal wells, tied back to the Jotun floating production, storage and offloading vessel (FPSO).
Det norske has signed supplier agreements with three contractors. Cameron has been selected to supply the subsea production system. They will, amongst other, fabricate the X-mas trees and protective structures.
Subsea 7 will be responsible for engineering, procurement, fabrication and installation of a 6 kilometer flexible flowline and jumpers, installation of a 6 kilometer integrated services umbilical, X-mas trees and protective structures. They will also supply diver assisted tie-ins.
Aker Solutions is given the assignment to fabricate the 6 kilometer integrated services umbilical.
