Field Development

Although the field was discovered 20 years ago, the plan for field development and operation wasn't agreed upon by licensees until 2006. Approved by the Norwegian Parliament in June 2007, Gjoa is the first development in the Sogn area, a new portion of the North Sea.

For a total investment of US $4.7 billion (NOK 29.3 billion), Gjoa is being developed by a semisubmersible production platform tied-back to five subsea templates. Field development plans for Gjoa include the satellite development of the Vega and Vega South fields nearby.

To reduce development costs, recovered hydrocarbons is transported through existing pipelines. Gas is transmitted via the British pipeline Flags to St. Fergus in Scotland. Oil is transported through a tie-in to the Troll II pipeline to the Mongstad refinery.

Semisubmersible Production Platform

There are three components related to construction and installation of the semisubmersible production platform. First, Aker Solutions was tapped in 2006 to fabricate and conjoin the topsides for the platform. The contract includes the detail engineering, procurement, construction and assembly of the topside and the connection with the platform hull.

Next, the partners awarded Leirvick Module Technology a $65 million (NOK 450 million) contract for the living quarters on the platform, comprising of a helideck, lifeboat station, living cabins and offices. Spanning nearly an acre, the 1,653-ton (1,500-tonne) living quarters will be able to accommodate 100 personnel.

In 2007, Samsung Heavy Industries was awarded the third supplier contract for the Gjoa platform. For a consideration of $150 million (NOK 900 million), Samsung is building the 15,432-ton (14,000-tonne) Gjoa platform hull. Assembly of the platform, including the hull, topsides and living quarters, will take place in Aker Stord, Norway.

Additionally, the Gjoa platform is the first floating platform to receive electricity from the mainland. A subsea cable, running from the Mongstad power plant north of Bergen, Norway, will supply the facility with electricity, reducing carbon dioxide emissions from the field.

Subsea Integration

The three-year, $427 million contract for the development drilling on Gjoa was awarded to Transocean Offshore in 2006. With a solid 13 wells on the schedule (nine oil wells and four gas wells), there are options for another three wells to be drilled during the contract. The Transocean Searcher semisub began Gjoa operations in January 2009.

Awarded in December 2006, FMC Technologies will provide 14 xmas trees and five subsea templates with manifolds for the development of Gjoa. The scope of the contract encompasses the production control systems, workover systems for well interventions and an umbilical option.

Italian Saipem was awarded the export pipeline installation contract in October 2007. Using the Castoro Sei pipe-laying vessel and starting in April 2009, Saipem installed a total of 115 miles (185 kilometers) of pipe from the Gjoa and Vega fields. A 28-inch-diameter gas pipeline will span 81 miles (130 kilometers) from Gjoa to the Flags pipeline. A 16-inch-diameter, 34-mile (55-kilometer) pipeline will connect Gjoa to the Troll II pipeline.

In December 2007, Danish NKT agreed to supply the engineering, procurement and fabrication of seven flexible risers for a consideration of $72 million (NOK 500 million). The 14- to 16-inch-diameter risers will measure between 2,264 and 2,395 feet (690 and 730 meters) long.

Technip is providing the fabrication and installation of subsea structures, as well as tie-in of the pipeline systems. In a $72 million (NOK 500 million) contract awarded in June 2008, Technip was chosen to perform fabrication and installation of tie-ins and expansion loops and guards, as well as the tie-in of risers, in-field and export pipelines. Technip will also perform water filling, cleaning, dimension control and pressure testing of pipelines. The Scandi Arctic vessel will perform structural installations, while the Normand Progress and Fugro Saltire will perform the pipeline tie-in and prep.

The five subsea templates were installed in October 2008, and development drilling commenced in November 2008. Tow out of the platform is expected to be in 2010 and production should commence from the field in September 2010.

Satellite Fields

Vega, located in the northern part of the North Sea, is located 50 miles (80 kilometers) west of Floro on Blocks 35/8 and 35/11.

Consisting of the Camilla, Belinda and Fram B discoveries in the early 1980s, the Vega field is in 1,247 feet (380 meters) of water. With a daily peak production rate of 247 MMcf (7 MMcm) of gas and 25,000 barrels of condensate, Vega boasts recoverable reserves of 636 Bcf (18 Bcm) of gas and 26 million barrels of condensate. The satellite field was developed via two subsea templates tied-back to the Gjoa semisubmersible platform, and production commenced on Dec. 2, 2010.

Discovered in 1987, Vega South is a gas and condensate field located in about 1,214 feet (370 meters) of water on Block 35/9. Another satellite field in the Gjoa field development plan, Vega South will be developed by a subsea template that will be connected to Vega and, ultimately, to the Gjoa platform. Production from Vega South commenced on Dec. 2, 2010.

Additionally, plans call for the eventual tie-in of the Aurora field.

Production is expected to commence in September 2010 on Gjoa and in October 2010 from the two satellite fields, Vega and Vega South.

Gjoa
Producing - Nov 07, 2010 to -

Under Development - Jul 11, 2010 to Nov 06, 2010

On July 11, Statoil turned on Gjoa's power, making it Norway's first floating platform to get its electricity from the mainland.

Under Development - Jun 14, 2007 to Jul 2010

Gas will be transported in the British pipeline Flags to St. Fergus in Scotland. Oil will be piped via a tie-in to the Troll II pipeline and further to the StatoilHydro-operated Mongstad refinery near Bergen. Start-up of oil and gas production is expected in 2010.

Discovery (Appraised) - Aug 14, 1998 to Jun 13, 2007

The well was permanently abandoned on 12 August 1998 as a dry well.

Appraisal Drilling - Jul 13, 1998 to Aug 13, 1998

Well 35/9-4 S was spudded with the semi-submersible installation Transocean Leader on 13 July 1998 and drilled to TD at 1261 m in the Paleocene Lista Formation. Well 35/9-4 SR was spudded immediately after.

Discovery (Appraised) - Apr 04, 1991 to Mar 31, 1996

Well 35/9-2 was permanently abandoned on 3 April 1991 as a gas/oil discovery.

Appraisal Drilling - Jan 01, 1991 to Apr 03, 1991

Wildcat/Appraisal well 35/9-2 was spudded with the semi-submersible installation Vildkat Explorer on 1 January 1991 and drilled to TD at 2885 m in Caledonian basement. Due to hole angle problems, the well had to be re-spudded twice before drilling proceeded.

Discovery (Drilled) - May 08, 1989 to Dec 31, 1990

Well 35/9-1 was prepared for testing. It was suspended as an oil and gas discovery on 7 May 1989. Well testing was postponed for a re-entry after the TOGI assignment.

Exploratory Drilling - Apr 01, 1989 to May 07, 1989

Well 35/9-1 was drilled on the M ål øy Slope north of the Horda Platform with Transocean's Polar Pioneer. The well was drilled to a total depth of 2350 m in crystalline basement rock.

Vega South
Producing - Dec 02, 2010 to -

Under Development - Jun 14, 2007 to Dec 01, 2010

Vega South will be developed by a subsea template that will be connected to Vega and, ultimately, to the Gjoa platform. Production from Vega South is expected to start in October 2010.

Discovery (Appraised) - Apr 21, 1992 to Jun 13, 2007

Wildcat well 35/11-6 was permanently abandoned on 20 April 1992. The well contained a limited accumulation of live oil. It is classified as well with shows.

Appraisal Drilling - Jan 30, 1992 to Apr 20, 1992

Wildcat well 35/11-6 was spudded with the semi-submersible installation Sovereign Explorer on 30 January 1992 and drilled to TD at 3990 m in the Early Jurassic Statfjord Formation.

Discovery (Drilled) - Dec 05, 1987 to Jan 29, 1992

Wildcat well 35/11-2 was plugged and abandoned on 4 December 1987 as a gas and condensate discovery.

Exploratory Drilling - Jul 20, 1987 to Dec 04, 1987

Wildcat well 35/11-2 was spudded with the semi-submersible rig Treasure Scout on 20 July 1987 and drilled to TD at 4025 m in Early Jurassic rocks.

Vega
Producing - Dec 02, 2010 to -

Under Development - Jun 14, 2007 to Dec 01, 2010

Field development plans for Vega include two subsea templates tied back to the Gjoa semisubmersible platform. The PDO was submitted to the authorities on Dec. 15, 2006. The start up of production at the Vega field is planned for October 2010.

Discovery (Drilled) - May 22, 1982 to Jun 13, 2007

Exploratory Drilling - Jul 27, 1980 to May 21, 1982

Two wildcat wells were drilled and both reported discoveries. Wells 35/8-1 and 35/8-2 were drilled by the Sedco 704 to a depth of over 4300 m.
