Claim 19:
20. A method according to claim 18 wherein the method includes the further steps of locking open the sub-surface safety valve for running and installing an insert valve, by: pressurizing tubing of the work string and recording the pumped volume to indicate when the pressure across the sub-surface safety valve is equalized and fluid is being pumped through the flapper valve; run in the apparatus and engage the first and second profiles; jar up strongly to shear release screws of the sub-surface safety valve; jar down strongly to push the flow tube through flapper and to lock the flow tube in open position; pump down the valve control line to verify that fluid is pumping into the tubing of the work string via a bore of the sub-surface safety valve; pick up to disengage the apparatus and pull out of hole.
