註釋The deep-water Rockall Basin extends from southwest Ireland to north-west Scotland and constitutes the exploration frontier for oil and gas on the continental margin to the west of the British Isles. Up to the present time, oil company interest has focused on shallower areas of the UK continental shelf and west of Shetland. Hence the Rockall Basin has not been extensively explored and geological understanding of the basin is limited. Whereas over 10 000 commercial wells have been drilled on the UK continental shelf as a whole, only 12 of these have been drilled within, or on the margin of, the Rockall Basin. The earliest pioneering exploration of the basin was undertaken in the late 1960s and early 1970s. Exploration was encouraged by the UK government designating ownership of the Hebrides Shelf in 1971 and of the Rockall Trough and Rockall Bank in 1974. This provoked the acquisition of commercial nonexclusive 'speculative' seismic datasets. The first hydrocarbon exploration licence was granted in 1974 and the first deep well, a stratigraphical test, was drilled in 1980. The first potential oil well was drilled in 1988.
