Abstract
A downhole running tool (10) for use in positioning an item, such as a length of tubing (12) , in a bore comprises a body (11, 22) defining a fluid passage, an arrangement (20, 30) for creating a flow restriction, to create an increase in fluid pressure in the passage, and a fluid actuated retaining member (34) mounted on the body for engaging an item (12) to be carried into a bore on the tool (10). The retaining member (34) is in fluid communication with the body fluid passage above the flow restriction arrangement (20, 30) and is movable to a retracted position to release the item (12) by application of fluid pressure forces.
