PETROLEUM PLAY DISTRIBUTION, NORTH SEA GAS PROVINCE
NORTH SEA GAS PROVINCE Lower Permian discoveries still being made. The NW Europe fairway has ultimately recoverable reserves of 159 tcf Seven Carboniferous fields contribute 5% of UK gas production - fairway is in early stage of exploration
CARBONIFEROUS PLAYS, NORTH SEA GAS PROVINCE
CARBONIFEROUS PLAYS Majority of discoveries have been made in simple structural traps Recent successes in combined structural / stratigraphic plays, e.g. hanging wall traps Stratigraphic and deeper traps unexplored

HISTORICAL PREDICTIONS OF UK OIL PRODUCTION
UK daily production averaging 3MMBOE to 2010 Buoyant NW Europe economy Exciting potential for small, medium and large companies Government committed to facilitating innovative thinking, cost reduction and licence trading
ATLANTIC MARGIN
Around 65% of undiscovered reserves lie within 50 km of existing infrastructure Frontier basins of Atlantic Margin offer greatest potential for major new reserves - gas potential not yet assessed by DTI
