Drilling starts at Eldfisk

ConocoPhillips kicked-off the drilling campaign on its Eldfisk II project with Maersk Innovator. Five wells have been pre-drilled, and the drilling operations of the remaining 35 wells has now begun.

Eldfisk II is one of four fields that comprise the Greater Ekofisk Area, located in the southern North Sea 300km off Stavanger. The other associated fields in the complex are the Ekofisk, which ConocoPhillips says was the first field discovered on Norwegian Continental Shelf, Embla and Tor fields, all of which are operated by CononoPhillips on production license 018.

Eldfisk operates the remote Embla field, which is tied in via pipeline.

The large Eldfisk field was originally discovered in 1970 and brought online in 1974. In 2011, the development program for Eldfisk II began, with the goal being to both increase recovery and maintain stable production, ConocoPhillips said in a statement. The Eldfisk II development sees, among other changes, the addition of the 15,5000-ton Eldfisk 2/7 S platform, which has a total of 40 well slots for both production and water injection, which is expected to come online in 2015. ConocoPhillips places the production rate at 5000boe/d.

It is predominantly an oil field, although it also has some gas reserves.  Located in less than 70m of water, the Houston-based exploration and production giant says that the reservoir consists of naturally-fractured chalk (Cretaceous) located at depths of between 2700 and 2900m. The field and has been developed through five platforms, four of which are connected and known as the Eldfisk Complex.

As part of Eldfisk II, the existing Eldfisk 2/7 A platform will be converted into a wellhead platform, and pipeline infrastructure is being constructed.

ConocoPhillips places Eldfisk II’s expected recovery rate at 28.5% by the end of 2028, which is when its renewed license expires. However, it says that production is capable of continuing past that.

The platform’s topside was constructed at Kvaerner’s yard in Stord and installed in the field in May. Kvaerner is also completing the offshore hook-up work, which is planned to be completed by years end. Dragados Offshore constructed the jackets and Aker Solutions commissioned and modified Eldfisk’s installations.

ConocoPhillips operates the Eldfisk project (35.11%) on behalf of Total (39.9%), Eni (12.39%), Statoil (7.6%) and Petoro (5%).
