Development
Valhall is a field in the southern part of the Norwegian sector in the North Sea. The water depth is 70 metres. Valhall was discovered in 1975, and the initial plan for development and operation (PDO) was approved in 1977. The field was originally developed with three facilities for accommodation (QP), drilling (DP) and processing (PCP). Production started in 1982. A PDO for a wellhead facility (WP) was approved in 1995 and for a water injection platform (IP) in 2000. Bridges connect the platforms. A PDO for two wellhead platforms on the northern and southern flanks was approved in 2001. A PDO for Valhall Redevelopment was approved in 2007, and included an accommodation and processing platform (PH) to replace aging facilities on the field. The PH-platform is supplied with power from shore. A PDO for Valhall Flank West was approved in 2018. It includes a normally unmanned wellhead platform.

Reservoir
Valhall produces oil from chalk in the Upper Cretaceous Hod and Tor Formations. Reservoir depth is 2,400 metres. The Tor Formation chalk is fine-grained and has good reservoir quality. Considerable fracturing allows oil and water to flow more easily than in the underlying Hod Formation.
03.03.2018
Recovery
The field was initially produced with pressure depletion and compaction drive. Water injection in the centre of the field started in 2004. Chalk compaction as a result of pressure depletion and water weakening has led to seabed subsidence. Gas lift is used to optimise production in most of the production wells.
28.02.2017
Transport
Oil and NGL (Natural Gas Liquids) are routed via pipeline to the Ekofisk field and further to Teesside in the UK. Gas is sent via Norpipe to Emden in Germany.
17.03.2019
Status
The Valhall field has passed one billion barrels of oil equivalents produced, which is three times more than what was anticipated in the original PDO. A long-term strategy for the field is being developed. Several wells were drilled in 2018, and drilling will continue in the foreseeable future. The development of the western flank is advancing. The accommodation facility (QP) is no longer in use and is awaiting disposal. Plug and abandonment of wells is ongoing on the DP facility.
