41. 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

42. ATLANTIC MARGIN

43. 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
