Claim:
A completion tool for deployment within a wellbore on tubing string, the assembly comprising: upper and lower sealing members defining a straddle zone between the upper and lower sealing members; one or more treatment ports within the straddle zone, the treatment ports continuous with tubing string to allow fluid delivery to the wellbore from surface; a valve housing mounted beneath the lower sealing member, the valve housing defining a fluid passageway continuous with the tubing string and with the wellbore annulus beneath the lower sealing member to allow pressure equalization therebetween; a bypass plug slidable within the valve housing between an open position in which fluid passage through the housing is permitted, and a sealed position in which fluid passage through the housing is prevented, the plug actuable to open or to seal the passageway upon application of mechanical pressure to the tubing string; and a resettable anchor device operatively mounted beneath the lower sealing member for setting against the casing of a wellbore, the anchor device operable by application of mechanical force to the tubing string.
