Abstract
A tool for fracking a formation at spaced intervals, which has an actuatable 'dump' port to flush an annular space surrounding the tool when in a wellbore to thereby flush sand and reduce tendency for 'sanding-in' of the tool in the wellbore. An uphole and downhole packer is provided, intermediate of which is a frac port. The dump port is located uphole thereof. Locking jaw members and a 'j' slot subassembly downhole of both the dump port and frac port are together used to set and unset the tool in the wellbore. A slidable sleeve opens and closes the dump port, which sleeve may be actuated by movement of the tool in the wellbore or alternatively by an actuating tool inserted in the bore of the tool. A method of carrying out fracking of the formation and flushing of the tool after each fracking operation is further disclosed.
