COPENHAGEN, Denmark – Two companies have submitted proposals for new platform-based developments in the Danish North Sea, according to the Danish Energy Agency (DEA).
In April, Wintershall Noordzee presented a plan for Phase 1 of the Ravn field development. This calls for a platform with two wells, and export of production through a multi-phase pipeline to Wintershall’s A6 platform in the German North Sea for processing.
Production could start in late 2015, with the wells delivering 2.9 MMcm of oil during their lifespan. Estimated cost is around $260 million.
In July Mærsk Olie og Gas submitted its Phase 1 plan for development of the Adda field, involving a new 16-slot, four-legged unmanned platform and drilling of eight wells. Production, due to start in late 2016, would head through an 8-in. liquids pipeline and a 12-in. gas line to Tyra East for processing.
Maersk estimates Phase 1 costs at $868 million, and expects the initial eight wells to produce around 5 bcm (3.6 tcf) of gas and 2 MMcm of condensate during their lifetime.
According to analysts ScanBoss, Maersk previously attempted to develop Adda in 2010 via an extended-reach well from the Tyra East platform. Adda’s lower Cretaceous reservoir presents production problems, which Maersk has been looking to address via the same slotted liner completion technology that it has applied through lower Cretaceous chalk in the Valdemar field.
