This tranche of blocks was awarded as part of the UK 32nd licensing round. The acreage contains the Bowmore discovery, which was discovered by the 15/24a-4 well in 1990 and appraised by the 15/24a-9 well in 2009. The producing reservoir comprises Upper Jurassic Galley Sandstone turbidites within a combination structural/stratigraphic trap, although hydrocarbons were also present within deeper Claymore and Piper sandstones. A significant number of additional leads have been mapped across the acreage, including structural fault-bound terraces and stratigraphic pinch-out plays, primarily at Piper Sandstone level.
