STAVANGER, Norway – Statoil (OSE:STL) has submitted a plan for development and operation (PDO) for the Dagny field in the Norwegian North Sea.
The concept is based around a steel jacket platform connected to the Sleipner field complex for gas export. Dagny’s oil will be transported by tankers.
Recoverable reserves are estimated at 225 MMboe.
Dagny, discovered in 1974, previously has been under consideration for development. Further appraisal during 2008-2011 confirmed a connection between Dagny and Dagny East, with large oil volumes below the structure.
The partners have agreed to pre-invest in equipment to facilitate a direct power link from the Norwegian mainland. One gas-fired turbine will be installed on the platform for power generation, but only will be used in the period until power from shore becomes available.
Statoil estimates the overall cost of the project at NOK 31 billion ($5.7 billion).
Following design studies by Norwegian and international supply companies, main contracts will be awarded during 2013. Earlier this year, Statoil contracted Maersk Drilling for the production well installations.
Plans call for Dagny to come onstream during 1Q 2017, and remain in service for 20 years.
As Dagny extends into license PL 029b, where Det norske oljeselskap is a partner, Statoil has agreed that Det norske can take a 3.3% stake in the Dagny field. Total is the other partner.
The PDO for the nearby Eirin gas field should be submitted next year. Here plans call for a template to be tied in to the Dagny platform.
