Intro
Ekofisk B is a fixed steel-jacket platform forming part of the original Ekofisk field development in the southern Norwegian North Sea. Installed in the early 1970s and first producing in the 1970s, it served as one of the primary production, drilling and accommodation structures in the Greater Ekofisk Area complex. The platform is tied physically and operationally into the broader Ekofisk infrastructure.
Field
The Ekofisk field lies in ~70-m water depth in the central North Sea and was discovered in 1969. It produces oil from naturally fractured chalk reservoirs of the Ekofisk and Tor Formations at ~3000-m depth. The field has a long history of development with multiple platforms and subsea installations serving production and injection functions.
Facilities
Ekofisk B originally featured production and injection wells, drilling modules and accommodation, forming part of the primary production complex feeding into central processing facilities. In its operational life it supported multi-phase separation, gas dehydration and crude handling before routing hydrocarbons to processing hubs like Ekofisk J. Produced oil and gas from Ekofisk B was exported via the Norpipe oil and gas pipelines to Teesside (UK) and Emden (Germany). Utilities included onboard power, produced water handling and control systems integrated with the Ekofisk Area supervisory suite. Over time many original Ekofisk I platforms have been decommissioned or had topsides removed as Ekofisk II facilities (e.g., Ekofisk J, X, M) assumed core processing functions.
