The invention provides a downhole initiator tool (10, 210, 410, 610) for use in initiating a downhole operation, and a method of use. The downhole initiator tool comprises a mandrel (34, 234, 434, 634), an initiator assembly (26, 226, 426, 626), and an anchor assembly (28, 228, 428, 628) mounted on the mandrel. The anchor assembly comprises a radially extendable anchor member (26, 226, 426, 626) for engaging an outer bore structure. The anchor assembly and the mandrel are axially moveable relative to each other in a first axial direction to sequentially extend the anchor member and activate the initiator assembly. |
