Intro
Ekofisk X is a fixed drilling and wellhead platform in the Ekofisk oil and gas complex in the southern Norwegian North Sea. Installed in 1996 and operational from 1998 as part of Ekofisk-II, it serves drilling and wellhead functions feeding hydrocarbons into the central Ekofisk processing hub and export systems. The platform is bridge-linked to Ekofisk-C and Ekofisk-J process facilities.
Field
The Ekofisk field lies in the central North Sea, discovered in 1969 and in production since the early 1970s. The reservoir is predominantly chalk of the Ekofisk and Tor Formations at ~3-km depth. Ekofisk is one of Norway’s first giant oil fields with significant recoverable oil and associated gas, developed through multiple platforms and extensive water-injection for pressure support.
Facilities
As a wellhead and drilling platform, Ekofisk-X hosts multiple production and injection well slots tied into the Greater Ekofisk reservoir. It facilitates drilling services and routes wellstreams via bridges to the Ekofisk-J processing platform where three-phase separation, dehydration and export compression occur. Produced oil and gas are exported via the Norpipe oil and gas pipelines to Teesside (UK) and Emden (Germany) respectively. Utilities include platform power generation, water handling and integrated control systems tied into the larger Ekofisk complex. It is designed for significant seabed subsidence due to chalk compaction and supports long-term injection programmes.
