Abstract
A thru-tubing recover string () and method of moving a stuck object () in tubing in a well (). A bottom hole assembly () is connected to a work string and includes a first () and a second tool (), each tool configured to apply a force to the object in order to move the object (), the first force being an impulse force, the second force being a static force, and the tools being operable independently so that an operator can apply either force in the event that application of one type of force on the object fails to move the object. Embodiments are described for the first tool () being a hammer tool or a jar and the second tool being a pulling tool such as a jack. The invention finds application in removing stuck objects such as plugs or actuating elements on tools such as sliding sleeves in production tubing.
