Summary Information

  • Operator: Maersk
  • Country: Denmark
  • Location: North Sea
  • Production start: 1993
  • Partners: North Sea Fund - 20%, Maersk - 31.2%, Shell - 36.8% and Chevron - 12.0%
  • Type: Oil / Gas
  • Estimated Reserves:
  • Production Volume:


  • The North Jens area of the Valdemar Field has been developed as a satellite to the Tyra Field with two bridge-connected, unmanned wellhead platforms, Valdemar AA and AB, without helidecks. Production is separated at the Valdemar AB platform.
  • The liquids produced are piped to Tyra East for processing and export ashore, while the gas produced is piped to Tyra West. The Valdemar AA/AB complex is provided with chemicals from Tyra East and with power from Tyra West.
  • The Bo area of the Valdemar Field has been developed with an unmanned wellhead platform, Valdemar BA, without a helideck. A 16” multiphase pipeline transports the production from Valdemar BA to Tyra East, via Roar.

  • 1977 - Valdemar Oil Field, Bo area discovered
  • 1985 - Valdemar Oil Field, North Jens area discovered
  • 1993 - First oil production from North Jens
  • 2007 - First oil production from Bo


  • The Valdemar Field consists of a northern reservoir called North Jens and a southern reservoir called Bo, which are both anticline chalk structures associated with tectonic uplift.
  • The Valdemar Field comprises several separate accumulations. Oil and gas have been discovered in Danian/Upper Cretaceous chalk, and large volumes of oil have been identified in Lower Cretaceous chalk. The extremely low-permeable layers in the Lower Cretaceous chalk possess challenging production properties in some parts of the Valdemar Field, while the Bo area has proven to have better production properties. The properties of the Upper Cretaceous reservoirs are comparable to other Danish fields like Gorm and Tyra.
  • The Upper and Lower Cretaceous reservoirs have been developed in both the Bo and North Jens areas.
