Wood Group has been granted a multi-million dollar, three-year contract by Chevron U.S.A. Inc. to commission the Big Foot extended tension leg platform (E-TLP) in the deepwater Gulf of Mexico. Work will be performed by DSI, Wood Group PSN's commissioning services business.

DSI's scope of work covers the full commissioning process, from development of procedures, through inspection and testing of every operational component at the South Texas fabrication yards and offshore, to the final hand-over of systems to Chevron.

Big Foot is the eighth TLP/ETLP DSI has commissioned worldwide and is the fifth facility commissioned for Chevron, including the Jack & St. Malo semi-submersible platform in the deepwater Gulf of Mexico, which DSI is currently commissioning.

"Commissioning is critical to the safe start-up of a production facility, proving the integrity and reliability of all safety and operating systems," stated Trey Lambert, president of DSI. "Chevron can rely on DSI to provide safe, consistent and quality commissioning services across its projects."

GE O&G' Drilling & Production business has received a contract of approximately $45 million to supply and service the industry's largest tension leg platform (TLP) marine riser Tensioner Systems to Chevron for deployment in its Big Foot oil and gas field in the deepwater Gulf of Mexico.

A TLP is a vertically moored floating structure suited for use in a wide range of water depths. GE is making key design modifications to develop 'push-up' style marine riser Tensioner equipment to enable the Chevron Big Foot oil and gas field TLP to deal with the challenging wave and current movement conditions of deepwater applications. To date, TLPs have been successfully deployed in water depths approaching 5,000 feet. The GE-Chevron Big Foot unit will be the first to operate in depths of 5,200 feet.

Manuel Terranova, senior vice president—global regions and sales, Drilling & Production, GE Oil & Gas said, "For this deepwater application, we are utilizing innovative technology to deliver customized 'push-up' style TLP Tensioners that offer Chevron an efficient and reliable solution for their challenging deepwater requirements. We are pleased to be supporting this important Chevron project which will contribute to the stability of future U.S. energy supply."

The Big Foot TLP will be Chevron's sixth operated facility in the deepwater Gulf of Mexico and will be located approximately 225 miles south of New Orleans. The TLP will include an on-board drilling rig and will have a production capacity of 75,000 barrels of oil and 25 million cubic feet of natural gas per day. Installation of the TLP is scheduled to begin in November 2012 and first oil is expected in 2014.

Baker Hughes Awarded Deepwater ESP Gig at Chevron's Big Foot Proj.

Chevron has awarded Baker Hughes a contract to supply electrical submersible pumping (ESP) systems and production packers for seven producing wells, plus mud line packers for three injection wells for their Gulf of Mexico deepwater Big Foot Project. This award marks the first deployment of ESP systems inside the wellbore in the deepwater Gulf of Mexico. The ESP systems will be placed at a true vertical depth of approximately 16,000 feet.

Discovered in 2006, Big Foot is in 5,200 feet of water in the Walker Ridge area of the Gulf of Mexico. The Big Foot production facility will be an extended tension leg platform with an onboard drilling rig and production capacity of 75,000 barrels of oil and 25 million cubic feet of gas. Deployment of the ESP systems is scheduled to begin in 2014.

ESP systems were selected to boost the production stream and maximize asset recovery while extending production life and accelerating recovery. Improved ESP technology and manufacturing controls has extended ESP run times for critical well applications. The 1200 horsepower dual ESP systems will be the highest horsepower in-well systems ever deployed in an offshore environment. The ESP systems are deployed on dual by-pass systems, allowing for reservoir access and the ability to switch between ESPs without intervention.

"Longer-term, the experience and knowledge gained from Big Foot can potentially be applied to other developments in the deepwater market to extend field productivity," said Richard Williams, president of the Gulf of Mexico for Baker Hughes. "We are happy to be working with Chevron on this groundbreaking project to extend the application of ESP technology in the deepwater environment."
