Although this is not an assessment of the resource volume of hydrocarbons, the table serves to identify those coastal states with ELCS areas that have some hydrocarbon resource potential. The top ten ranked countries, according to those with the greatest ELCS areas (cited in brackets by million km 2 ) containing sedimentary sequences in excess of 1 km thick and hence having potential hydrocarbon resources are: Antarctica (2.23), Canada (0.95), Brazil (0.95), USA (0.75), Sri Lanka (0.65), India (0.58), Argentina (0.52), Madagascar (0.49), Russia (0.41) and Morocco (0.33). The bottom ranked countries are: Kenya (0.02), Sierra Leone (0.02), the Congo Republic (0.015), Zaire (0.013), Guinea (0.012), Bangladesh (0.005), Mauritania (0.003), Equatorial Guinea, Tonga and Venezuela (each with ~0.001). In their report (Ranking Of The World's Oil And Gas Provinces By Known Petroleum Volumes), Klett et al., (1997), identify hydrocarbon resources for forty-one offshore provinces that contain known reserve volumes. These areas are shown on Figure 21 in green and listed on Table 4, which also show their oil and gas volume potentials. Although none of these provinces coincide with the ELCS regions, their proximity to those regions, accumulated thickness of sediment, and the basement type are combined to indicate hydrocarbon potential from high to low (Figure 25). On the basis of known hydrocarbon volume reserve, the top ten ranked offshore provinces identified by Klett et al. (1997) are identified in Table 7 below (by province number – referred to on Figure 21, and billion barrels oil equivalence (BBOE) of oil and gas). Also identified are the ELCS regions (by number, referred to on Figure 7) and their coastal states, that lie closest to each of the USGS identified hydrocarbon provinces. The top ten ranked provinces are given in Table 7. Table 7 gives an indication of the relationship between known reserve volumes and the adjacent ELCS regions where there is significant hydrocarbon potential. IINTERNATIONAL SEABED AUTHORITY 724
