The Government of Dubai and Dubai Petroleum Company (DPC) announced a joint agreement that will change the operating arrangements for Dubai offshore oilfields. Effective April 2007, DPC will end its role as operator, marking the end of Dubai's first offshore oil concession and the beginning of a new phase in which the Emirate of Dubai will directly control its offshore oil resources. DPC is wholly owned by ConocoPhillips and part of the DPC/Dubai Marine Areas Limited (DUMA) consortium involving interests from Total (France), Repsol YPF (Spain), RWE Dea AG, a subsidiary of RWE AG (Germany) and Wintershall AG, a subsidiary of BASF (Germany).
