Statoil's deepwater Bay du Nord oil discovery in the Flemish Pass basin off Newfoundland & Labrador could hold up to 600 MMbbl recoverable. The company upped its estimate following a side track well drilled by the semisubmersibleWest Aquarius in 1,100 m (3,609 ft) of water, which encountered 34°API oil in good-quality Jurassic reservoirs. Along with the nearby Harpoon and Mizzen oil finds there is potential for a major deepwater production hub, Statoil claimed.
Pemex has signed a memorandum of understanding with Keppel Offshore & Marine to jointly develop and operate a yard in Mexico, at an estimated cost of $400 million. Their plan is to initially equip the site to construct components of six Keppel-designed KFELS B jackups for the Mexican sector. Under future phases its capability could be expanded to repairs of deep-draft semis and drillships, topsides fabrication, and FPSO/FLNG vessel conversions. The full program would create up to 4,000 jobs.
Shell has started production from the second-phase development of the Parque das Conchas (BC-10) project offshore southeast Brazil. Phase 1, which came onstream in 2009, involved subsea tiebacks of the Abalone and Ostra fields and the Argonauta B-West reservoir to theEspirito Santo FPSO. Under Phase 2, the newly connected Argonauta O-North will boost overall production by 35,000 boe/d. Shell has also installed what it claims is the world's most extensive deepwater 4D life-of-field seismic monitoring system, in 1,800 m (5,905 ft) of water. Two more subsea tiebacks are under way in the current third-phase development, which will add a further 28,000 boe/d.
