Chevron selects MARS system for Subsea production optimization in Angola

Published Oct 7, 2008

Cameron has confirmed an order of 14 MARS™ (Multiple Application Re-injection Systems) for the long-term subsea production optimization strategy on Chevron’s Lombito Tomboco Field in Angola. The order is initially valued at $16M and represents another significant commitment by a major operator to the MARS production interface which has been described as “a USB port for wellheads.”

MARS has been previously used by BP for subsea multiphase pumping in the Gulf of Mexico and is scheduled to be deployed by Total in Angola and Shell in the North Sea for subsea multiphase metering and well stimulation respectively.

The patented MARS system is a Cameron technology, supplied by DES Operations of Aberdeen, a wholly owned subsidiary of Houston-based Cameron. The technology enables multiple processing technologies to be retrofitted onto subsea Christmas trees and is being applied by Chevron to perform subsea chemical squeeze
operations on existing wells in Angola. Chevron and DES have integrated the MARS system into an existingsubsea infrastructure enabling chemical scale squeeze operations from an ROV support vessel, eliminating the need for MODU support.

Ian Donald, Cameron’s vice president at DES said, “We are delighted at the adoption of the MARS system by Chevron. The MARS interface is adaptable to any subsea tree enabling the integration of a variety of processing equipment to an operator’s asset.”

A Chevron representative for the project added, “We have worked closely with DES to develop a cost effective well intervention system which allows us to significantly minimize the downtime and maximize the production associated with subsea chemical stimulation operations.”

In addition to the 14 MARS systems, DES will provide the chemical delivery system for Chevron’s project.
