Valhall and Hod have passed one billion barrels of oil equivalents (oil, gas and NGL) produced – thus more than three times what was expected at the opening of the field in 1982.
Hod, which produces via Valhall, has delivered over 75 million barrels of oil equivalents and this is more than twice the estimated oil at field start-up in 1990.
Valhall’s oil and gas is produced from chalk reservoirs sitting ~2500 meters below seabed in the southern part of the North Sea.
The activity level on the field has been high, with almost continuous drilling since start-up. Seismic and well technologies are key leavers for developing the field. The current well stock comprises 55 active wells out of a total of nearly 150 productive wells drilled since field discovery. 18 seismic 4D seabed surveys have been acquired since 2003.
“In 1995, work was performed with the goal to extend the field lifetime and recover more than one billion barrels of oil equivalents. We have now achieved this goal 15 years ahead of what was thought at the time. Our new ambition is to further produce at least another 500 million barrels of oil equivalents”, says Eldar Larsen, Senior Vice President of Operations in Aker BP.
Valhall is and has been a big and important workplace. Thousands of jobs are directly and indirectly dependent on field operations. Our goal is safe and profitable production from Valhall for several decades ahead.
Facts about Valhall
- Licensees: Aker BP 35.9% (operator), Hess Norway AS 64.1%.
- Valhall field was discovered in 1975 and put into production in 1982 with a process / production platform, a drilling platform and an accommodation platform. Production from the new process / accommodation platform started in January 2013.
- Today the Valhall complex consists of six separate steel platforms. The platforms are connected by footbridges. In addition the field has two unmanned flank platforms, one in south and one in the north, both ca. 6km from the field center.
- Production capacity for oil is 120,000 barrels per day. Average daily production level in 2016: about 45,000 barrels of oil equivalents per day.
- Gas handling capacity of 4 million standard cubic meters per day.
- The field is powered from shore via a 294 km long DC cable with 78MW capacity from Lista.
Facts about Hod
- Licensees: Aker BP 37.5% (operator), Hess Norway AS 62.5%.
- Hod is a normally unmanned wellhead platform. It is remotely controlled from Valhall 13 km away, and was the North Sea’s first unmanned platform when production started in August 1990.
- Production ceased from the Hod Platform in 2012. Today the Hod licence produces from wells drilled from Valhall Flank South Platform.
- Decommissioning plan for the Hod platform is submitted to the Ministry of Petroleum and Energy (MPE).
