Intro
Eldfisk A is a fixed platform on the Eldfisk field in the southern Norwegian North Sea, originally installed as an integrated wellhead and process structure in the late 1970s. It sits within the Greater Ekofisk Area and was part of the field’s original trio of facilities alongside Eldfisk B and FTP. Over time its role has shifted toward primarily wellhead functions with other processing largely migrated to Eldfisk S.
Field
The Eldfisk field lies ~10-km south of Ekofisk in ~70-m water depth and was discovered in 1970. It produces oil (with associated gas) from chalk reservoirs of the Hod, Tor and Ekofisk Formations. Eldfisk was developed with bridges linking its platforms and subsea tie-backs, with production starting in 1979.
Facilities
Eldfisk A originally integrated drilling, production and early processing modules, receiving hydrocarbons from wells on the field’s structural highs. With the Eldfisk II development including Eldfisk S, many primary separation and dehydration functions have been superseded; A now acts principally as a wellhead support platform, maintaining well connections to processing trains on Eldfisk S or FTP where needed. Its infrastructure comprises manifolds, flowlines, and basic control systems for routing fluids toward central processing. Utilities include platform power, safety and communications systems that interface with the larger Eldfisk complex and connected Ekofisk export infrastructure. Oil and gas from Eldfisk are exported via pipelines tied back through Ekofisk’s export routes (Norpipe) to Teesside (oil) and Emden (gas).
