| Description |
| |
Located in the Norwegian sector of the North Sea is the Greater Norne Area, consisting of three fields, Norne, Urd and Alve. The main field and its satellites shall produce hydrocarbons until 2021.
At the time of Norne's discovery in December 1991, it was one of the largest oil discoveries on the Norwegian Continental Shelf, estimated to hold recoverable oil reserves in the amount of 450 million barrels of oil.
Norne
Norne is situated on Blocks 6608/10 and 6608/11 in Production License 128 and lies in waters measuring 1,247 feet (380 meters), roughly 870 miles (1,400 kilometers) from land at Dornum in Germany. Statoil operates the field, holding a 39.1% interest; Petoro holds 54%; and Eni Norge AS holds the remaining 6.9% interest.
The discovery well, 6608/10-2, contained a total hydrocarbon column of 443 feet (135 meters) - a 361 foot (110-meter) oil column with an overlying gas cap. In 1993, an appraisal well, 6608/10-3, was drilled on the northern part of the Norne structure, confirming the results from the discovery well, and proved the extension of the field to the north. Another appraisal well, 6608/10-4, was drilled in a structure 1 to 2 miles (2 to 3 kilometers) east of Norne in early 1994, and discovered a minor oil accumulation.
In 1993, development began by the Norne FPSO, which is connected to five well templates - three for production, one for water injection and one for combined gas and water injection. Each template has four slots and the capacity to tie in additional satellite wells. The templates are tied-back to the production ship by two nine-inch production lines, one nine-inch water-injection line and one control and service umbilical.
Flexible risers carry the wellstream to the FPSO, rotating around a cylindrical turret moored to the seabed by a 12-point mooring system. Processing facilities and power units are installed on deck. The topside production systems compromise oil separation and produced water treatment, gas separation and compression, power generation, water injection, export metering, chemical injection and a heating and cooling medium.
Oil production is processed and stored aboard then offloaded to tankers, while gas output is piped to the Norwegian mainland via the Norne and Asgard pipelines.
Norne commenced production on Nov. 6, 1997.
Urd
Located on Block 6608/10 in Production License 128 is the Urd field. Statoil, holding a 64% interest, operates the field; Petoro holds 24.50%; and Eni Norge holds the remaining 11.50% interest.
Field development for Urd embraces two satellites, Staer and Svale, and a total of five oil producers and three water injectors connected to the Norne FPSO. Staer is located 3 miles (5 kilometers) north of the main field and was developed by a single seabed template tied-back to the Norne FPSO. Svale is situated 6 miles (10 kilometers) to the north of Norne and produces through two subsea templates tied-back to the vessel.
Estimated to hold 70 million barrels of oil and a small amount of gas, the Urd field commenced production on Nov. 8, 2005.
Alve
The Alve gas and condensate field is located 10 miles (16 kilometers) southwest of the Norne field in the Norwegian sector of the North Sea in Production License 159B. Statoil serves as the operator, holding an 85% interest; Dong E&P Norge holds the remaining 15% interest.
Discovered in 1990, the Alve development combines the Garn, Not Iie and Tilije formations, and holds an estimated 6.78 Bcm of gas and 8.3 million barrels of condensate.
A plan of development was submitted to the Ministry of Petroleum and Energy in January 2007, and approved by the ministry in March of that same year. Alve was developed as a subsea tieback to the Norne FPSO. Gas is exported through the pipeline systems established at Norne.
Commencing production on March 19, 2009, Alve produces roughly 4 MMcm/d. Output from Alve will extend Norne's lifetime from 2016 to 2021.
Additional Discoveries
Marulk
Situated on Blocks 6507/2, 6507/3, 6607/12 and 6607/11 in a water depth of 1,250 feet (381 meters) is the Marulk field. Eni holds a 20% operating interest of Marulk; Statoil holds 50%; and DONG holds the remaining 30% interest.
Discovered in 1992, the Marulk field will consist of two wells tied-back to the Norne FPSO.
In March 2010, FMC Technologies received a contract to manufacture and supply subsea production equipment for the field's development. FMC's scope of work includes manufacturing two subsea trees, one manifold, one template, subsea control modules and associated topside controls and connection equipment. Initial equipment deliveries commenced in the second quarter of 2011.
The field came online on April 5, 2012 at a production rate of about 20,000 boep/d.
Fossekall
Located in 1,155 feet (352 meters) of water is the Fossekall field, situated in Production License 128 on Block 6608/10 in the Norwegian sector of the North Sea. Serving as the operator of the license is Statoil, holding a 63.95% interest; Petoro holds 24.54%; and Eni Norge holds the remaining 11.50% interest.
In April 2010, Statoil discovered oil and gas in the 6608/10-14 S well. Drilled by Diamond Offshore's Ocean Vanguard semisub, the well reached a total vertical depth of 9,019 feet (2,749 meters), ending in the Are formation in the lower Jurassic. The proved recoverable resources are provisionally estimated at 37 and 63 MMbbl, and associated and free gas is estimated at 1 to 3 billion standard cubic meters.
A field development option the operator is considering is tying the well back to existing Norne infrastructures.
Dompap
The Dompap discovery is located on Block 6608/10 in 1,109 feet (338 meters) of water. Statoil holds a 64% interest; Petoro holds a 24% interest; and Eni holds the remaining 12% interest.
An oil discovery was made on the Dompap prospect, just north of the Norne field in January 2009. The exploration well 6608/10-12 was drilled to a vertical depth of 10,361 feet (3,158 meters), terminating in the Lower Jurassic rocks of the Are formation. Then a drilled sidetrack well, 6608-12 A, went down to a vertical depth of 9,616 feet (2,931 meters), terminating in the same formation. The Ocean Vanguard performed drilling operations. The field is estimated to hold roughly 25 to 50 million barrels.
Dompap will also be subsea tied-back to the Norne FPSO.
Skuld
The Skuld satellite field is located on Block 16/2 in the Norwegian sector of the North Sea. Statoil serves as the operator of the field with a 64 percent stake; Eni holds 11.5%; and Petoro holds 24.5%.
Skuld, a fast-track development, will be developed by three subsea templates with six production wells and three water injectors connecting to the Norne FPSO through a 14-inch-diameter production flowline and umbilical.
The field is scheduled to come online by late 2012. Recoverable reserves in Skuld are estimated at 90 MMboe, primarily oil.

| Alve reserves upgraded |
Date: Apr. 2004
Type: Appraisal Operations |
| Proven reserves of gas and condensate in Statoil’s Alve discovery in the Norwegian Sea have been upgraded following the completion of an appraisal well.
This find lies 10 kilometres south-west of the group’s Norne development.
The 6507/3-4 appraisal was drilled in 372 metres of water to a total measured depth of 4,092 metres below sea level and terminated in early Jurassic rocks.
Cores were taken during the drilling operation, which lasted for 47 days, and extensive well logging was carried out.
“It’s too early to say anything about the size of recoverable reserves proven so far in Alve,” says Roger Inge Johansen, sector manager in the exploration Norway cluster for Halten/Nordland.
“We’ll be evaluating all the information obtained from this well to clarify the potential of the discovery.”
Alve will primarily be assessed for a tie-back to the Norne production ship, but this will depend on its size. Statoil also intends to evaluate another appraisal well.
When Alve was proven in 1990, it put the group on the track of the Norne discovery.
The present well was drilled from the West Navigator drill ship, which left the location yesterday, 29 April, to spud a wildcat on the Linerle prospect 20 kilometres north-east of Norne. |

| New well on Alve |
Date: Mar. 2004
Type: Appraisal Operations |
| An appraisal well on Alve was spudded yesterday, 14 March, by operator Statoil. This small gas and condensate discovery in the Norwegian Sea lies close to the group’s Norne field.
“We’re hoping to establish that the field is considerably larger than has already been proven,” explains Knut Chr Grindstad, exploration manager for the Halten/Nordland cluster.
“In our view, there’s a good chance that possible additional resources in Alve will be oil.”
The partners must identify more oil or gas in the discovery if they are to achieve a profitable development, he explains.
Maturing and harnessing smaller fields located close to existing infrastructure is also important for Statoil, Mr Grindstad adds.
The Alve well is being drilled by the West Navigator drill ship (formerly West Navion), with six weeks assigned for the operation.
Once this appraisal has been completed, the vessel is due to drill a further exploration well in the Halten/Nordland area.
Statoil has a 50 per cent interest in Alve. The other owners are Shell with 40 per cent and Norsk Hydro with 10 per cent. |

| Drilling Near Norne |
Date: Dec. 1998
Type: Status Update |
| An exploration well was spudded by Statoil over the Christmas period in Norwegian Sea block 6507/3, south-west of its Norne field.
Located 220 kilometres west of Brønnøysund, this acreage yielded a gas and condensate discovery in 1990 which has been named Alve. Two dry wells have also been drilled in the area.
It was the Alve find which put Statoil on the track of its Norne find, and Amoco recently made an oil and gas discovery just to the south of 6507/3.
Being drilled by Byford Dolphin, the well is due to take about 70 days to complete. It will go down to a depth of about 3,800 metres in 392 metres of water.
Statoil has a 50 per cent interest in production licence 159, including 20 per cent for the state's direct financial interest. The other partners are Enterprise with 40 per cent and Saga 10 per cent.
Block 6507/3 lies 30 kilometres from Norne and 50 kilometres from Statoil's Heidrun field. A possible development of the area could accordingly utilise existing infrastructure. |
