CONOCOPHILLIPS has selected Australian group WorleyParsons to provide front end engineering design (FEED) definition and advanced procurement services for its Jasmine Area Development project.
This is WorleyParsons’ first major offshore platform award in the North Sea.
The Jasmine gas condensate project straddles UK blocks 30/6 and 30/7 in the Central North Sea. It lies about nine kilometres west of the Judy production platform, to which it is to be tied back.
WorleyParsons said the contract includes an option for the detailed engineering of the Jasmine field and follows its successful performance of the Jasmine FEED optimisation services.
The company is performing the work from its offices in London, Woking and Kuala Lumpur.
The Jasmine development will utilise the existing processing capacity on the nearby Judy platform and, in summary, comprises the following:
Accommodation and utility platform bridge-linked to the wellhead unit.
Judy riser and separation platform with additional Judy well slots bridge-linked to the existing Judy platform.
Multi-phase pipeline from the wellhead unit to the Judy riser platform.
Although the seabed footprint of this option is greater than the subsea option also contemplated, ConocoPhillips says the seabed footprint will be minimised by reducing the size of the accommodation platform.
It is claimed that associated CO emissions will also be lower than the wellhead platform with the integrated drilling rig and living quarters.
This development concept allows for well interventions to be carried out without the requirement for a jack-up rig by using coiled tubing and wireline equipment, and also provides the ability to deal with any production-assurance and reservoir-management issues locally. A jack-up rig will be used, as required, for major well intervention works. ConocoPhillips is the operator of the Jasmine project with 36.5% interest, in partnership with Eni UK, holding 33%, and BG Group, with 30.5%.
