REGIONAL UPDATE AFRICA Z Chariot Oil & Gas acquired operatorship and 75% equity interests in two exploration blocks some 30 miles offshore Morocco— Loukos and Casablanca/Safi—from Maghreb Petroleum Exploration in return for taking on work commitments and obligations in the initial exploration phase of each license. The Moroccan Office National des Hydrocarbures et des Mines holds the licenses’ remaining 25%. in the UK central North Sea. The Kinnoull field is one of three reservoirs being developed as part of the rejuvenation of the Andrew area, with the aim of extending production a further decade. In order to access the new reservoir, the project has installed a new subsea system and caisson onto the Andrew platform.

Z BP capped and plugged an abandoned piece of subsea equipment known as a cofferdam believed to be the source of a recent surface oil sheen observed near Mississippi Canyon 252 Block in the GOM off Louisiana. The cofferdam is a 40-ft-tall, 86-ton, steel container that was lowered in 2010 over a leaking drill pipe during oil-spill response efforts following the deepwater Macondo well blowout.
