The Gannet G discovery was the third made in the early Eocene Tay Formation on block 22/21 . This block is located in the southern part of the West Forties Basin. Large-scale, basin fl oor, Tay submarine fan sandstones sourced from the north-west and directly from the west via the Dandy-Fyne-Guillemot West channel are well developed across the block. An axial dip-closure provides the trap for the Gannet D field in the northern part of the block and a large pinchout onto the western basin margin the stratigraphic trap for the Gannet A oil and gas fi eld.
