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.
Valhall field, located in the south part of the Norwegian North Sea, 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. 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 at about 6km from the field center. Aker BP is the operator with a 35.9% stake Hess holding 64.1%.
