Intro
Fixed water-injection platform in the Eldfisk area of the Norwegian North Sea, installed in 1999 to support reservoir pressure maintenance and water injection. It also supplies treated water to Ekofisk K via a dedicated subsea pipeline. It has no primary production processing role but is bridged to Eldfisk S for utility and reservoir support functions.
Field
Eldfisk Field – Oil and gas accumulation in block 2/7 of the Norwegian central North Sea, producing from Chalk formations of the Ekofisk, Tor and Hod Formations. Discovered in 1970, production started in 1979; the field has multiple structural segments (Alpha, Bravo, Øst) with complex reservoirs requiring pressure support. The Embla satellite is tied to the Eldfisk complex.
Facilities
Eldfisk E is primarily a reservoir support and injection facility, not a central processing hub. It receives produced water from other Eldfisk platforms, treats it, and injects it into reservoirs via high-pressure pumps. The platform is connected by bridge to Eldfisk S which hosts process support functions (water handling, utilities) and control systems. Downhole injection wells extend from the deck, and there are subsea tie-backs for water transfer to Ekofisk K for cross-field reservoir support. Utilities include gas turbine power generation, treated water systems, injection pumps, chemical injection skids, control/data acquisition systems, and flaring connections as necessary for safe operation. No long-term export separation or hydrocarbon processing is conducted on Eldfisk E; liquids and gas flows from Eldfisk and Embla are processed via the Eldfisk S complex and exported via pipelines through the Ekofisk Centre.
