932 giant oil and gas fields account for about 50±10% of the world's petroleum reserves. In the period of 2000-2006, 33 new oil giants and 36 new gas giants were added to the existing 863 oil and gas giants discovered in the interval of 1868-1999. We have identified several dominant clusters of giants occupying specific tectonic settings. Most clusters of 2000-06 discoveries occupy established provinces like the rift/collisional setting of the Persian Gulf (6 oil/5 gas giants, or 15% of the new discoveries), the passive margin setting of northwest Australia (8 gas), the passive margin of west Africa (5 oil/2 gas), the passive margin of the deepwater GOM (6 oil), and the passive margin of Brazil (7 oil/3 gas). However, new emerging clusters include the passive margin setting of India and Mynamar (3 gas) and the collisional basins of western China (1 oil/3gas). Other giant clusters include: rift setting of the Western Siberian basin (1 gas), rift and collisional setting of the Caspian Sea (3 oil/2 gas), collisional and strike-slip setting of northern South America (1 oil/1 gas), subduction setting of Indonesia (2 gas), rift setting of the North Sea (1 oil) and northern Africa (1 oil), and passive margin setting of Norway (1 gas). Despite the steady decline in the discovery of new giants since 1970, we predict 33 future oil and gas giant discoveries will be made during the remainder of this decade. This tally would make 2000-2009 the third highest discovery decade in history.
