Petrobras Strikes Oil in U.S. Gulf of Mexico


Petrobras last week announced a new oil discovery in the extreme southwestern part of the Walker Ridge concession area, located in America’s Gulf of Mexico ultra-deep waters. The discovery confirms the Lower Tertiary’s potential in this area.

The Logan discovery is approximately 400 km (250 miles) southwest of New Orleans, at a water of around 2,364 meters (7,750 feet). The discovery was made by drilling operations of well WR 969 #1 (Logan #1), in block WR 969. Further exploration activities will define Logan’s recoverable volumes and its commercial potential.

Statoil is the consortium’s operator, with 35% stake. Petrobras America Inc. (a subsidiary of Petrobras headquartered in Houston, Texas) holds 35% of the stake, while Ecopetrol America and OOGC hold 20% and 10%, respectively.

Petrobras in the Gulf of Mexico

As a world leader in deepwater operations, Petrobras benefits from the experience and technology the company developed in its offshore operations in Brazil.

In the Gulf of Mexico, Petrobras is the operator of Cascade (100%) and Chinook (66.7%) oilfields and holds stakes in the Saint Malo (25%), Stones (25%) and Tiber (20%) discoveries, all with significant oil reserves in the Lower Tertiary. Additionally, Petrobras has stakes in the very recent Hadrian South (23.3%), Hadrian North (25%) and Lucius (9.6%) discoveries, all with significant oil reserves and in the Mio-Pliocene.

Petrobras holds other exploratory concession areas in this region, which will be tested later on, growing the Company’s operations in the Gulf of Mexico.

USA: Chevron Selects McDermott for Jack and St. Malo Fabrication and Installation Work


McDermott International, Inc. , announced today that one of its subsidiary companies was awarded fabrication and installation work from Chevron U.S.A. Inc. to support the development of the Jack and St. Malo fields in the Gulf of Mexico. The project will be included in McDermott’s first quarter 2011 bookings.

Work will begin in 2013, with the start of fabrication of 21 rigid jumpers at McDermott’s Morgan City fabrication facility in Louisiana. Offshore installation will begin in early 2014 using McDermott’s subsea construction vessel North Ocean 102 (“NO102”) and the DB16.

“We are pleased to be able to support Chevron’s deepwater developments in the Gulf of Mexico and believe that our combined solution of NO102’s high payload and top tension capacity coupled with our ability to fabricate the high spec jumpers in house provides a unique benefit for this project’s delivery,” said Stephen M. Johnson, President and Chief Executive Officer of McDermott.

The NO102 and its crew will transport and install more than 60 miles of umbilicals, including three control and two power umbilicals. The jumpers and remaining subsea controls system components, including more than 80 flying leads, will be installed by the DB16.

Located in up to 7,150 feet of water in the US Gulf of Mexico Walker Ridge lease blocks, the Jack South and St. Malo North and South subsea drill centers tie back to the Jack and St. Malo floating production platform.

More about North Ocean 102

The 427-foot NO102 enables McDermott to offer versatile installation capabilities in the flexible pipe and product market worldwide. The vessel has two cranes and a moon pool to support deepwater subsea construction work and has a fast transit speed. It is currently equipped with a 7,000-ton capacity cable and umbilical and flexible pipe carousel with horizontal lay system. Plans are underway to upgrade the vessel’s capability by installing a high-capacity flexible-lay system for ultra deepwater installation work. The upgrade will include installation of a new 250-ton crane.

North Ocean 105 (NO105), the sister ship to NO102, is currently under construction at a Spanish shipyard. The 427-foot vessel will be outfitted with a high capacity rigid-reeled pipe-lay system with top-tier payload capacity. The system will also accommodate installation of flexible products including submarine cables and umbilicals and flexible pipelines. The anticipated delivery date of the NO105 is 2012.

USA: Chevron Selects MyCelx for Jack/St. Malo Water Treatment System Delivery


MyCelx, experts in produced water treatment both onshore and offshore for discharge to very low discharge limit, the ISO-9001 company certified for oil removal to less than 5 ppm by Lloyd’s Register, signed a contract with Chevron U.S.A. Inc. to design and deliver a produced water treatment system for the Jack/St. Malo floating production facility in deepwater Gulf of Mexico that will remove oil and water soluble organics (WSO) to below 10 parts per million (ppm).

The design requirements for the Jack/St. Malo floating production facility calls for an overboard discharge limit that Is lower than the current EPA limit of 29 ppm, and MyCelx is one of the few companies providing the technology that can guarantee low levels of oil and grease discharge levels in a consistent manner through an economically viable process. The WSOs contained in offshore produced water have proved difficult for conventional technologies to reliably meet the overboard discharge specifications set by the EPA.

“MyCelx system guarantees oil-free water and no sheen discharge into the environment,” said Andy Narayanan, Manager of Operations and Technical Services at MyCelx.The Jack/St Malo will be implementing MyCelx produced water treatment system specifically designed to handle the difficult WSO’s from deep water drilling operations. We are currently in the process of design discussion with Chevron and Mustang. Current schedule is to deliver the system to Mustang Engineering by May 2011.”

The Jack and St. Malo fields are being developed in the Lower Tertiary trend in deepwater Gulf of Mexico. The fields are estimated to contain total recoverable resources equivalent to more than 500 million barrels of oil. MyCelx produced water treatment system will treat up to 70,000 barrels per day.
