is an oil field in the Norwegian
sector of the North Sea
. Discovered in 1975, production began in 1982 and is expected to continue until 2050. Valhall is located in 70 metres of water.
The field was originally developed with three facilities (QP, DP and PCP) but now the complex consists of five separate steel platforms
that are bridge-connected. There are also two unmanned flank platforms, one in the south and one in the north, both around 6 kilometres from the field centre.
Quarters Platform (QP)
The QP was built in 1979 and started being used in July 1981. It has accommodation for 208 people.
Drilling Platform (DP)
The DP is situated centrally and has 30 well slots. The platform started operation on 17 December, 1981 with the first covered derrick
Production Platform (PCP)
The PCP is built to process of oil
and of gas
per day. The platform is 65 metres high and weighs 21,000 tons. The oil production is piped to 2/4-J at the Ekofisk Center
and goes to Teesside
. The gas is transported directly via the Norpipe pipeline
. The platform also processes oil and gas that comes from the Hod oil field
Wellhead Platform (WP)
The WP was installed in April 1996 and first oil production started in June the same year. WP has 19 well slots. A central location and spare available capacity make it possible for the Valhall complex to also receive oil and gas from several adjacent fields.
