Xodus Enhance Technology Offering in Bream Project

28 September 2012

International energy consultancy Xodus Group recently completed one of its largest subsea contracts worth more than £2 million with BG Norge, a BG Group business, on the Bream development project, offshore Norway.

The Bream field is in block 17/12 of the Norwegian sector of the North Sea, approximately 110 kilometers west of Egersund and about 50 kilometers northwest of the Yme field.

The 10-month scope of work involved a Front End Engineering Design study (FEED) for the entire subsea system from the FPSO to the wells. This included subsea engineering, pipeline design and riser analysis as well as developing functional specifications and scopes of work for the execute phase. The project involved a number of complex issues within the subsea system including flow assurance and riser system work.

Production is from five producer wells and deploys downhole Electrical Submersible Pumps (ESP). In addition Simultaneous Water and Gas (SWAG) injection will be used via two additional injection wells. Xodus was also tasked to develop the associated tree specifications, a new area of technical expertise for the company.

Xodus also deployed its new computational fluid dynamics technology to analyse the commingling of the water and gas prior to entering the injection wells.

A dedicated team of more than 20 people from Xodus’ subsea engineering team based in London, Aberdeen and Oslo have carried out more than 18,000 man hours to date on the project. Andrew Wylie, project manager from Xodus, oversaw the project. "Our flow assurance and subsea teams across our London, Aberdeen and Oslo offices have collaborated on one of the most significant subsea projects Xodus has completed. This not only allowed the team to demonstrate its in-depth expertise and skills but also the successful deployment of some of our newest technology.”
