A ported housing that may be connected along a casing string and the method for use of the ported housing in fracturing and/or treating multiple zones in a well. A sleeve is connected to the ported housing and may be moved between an initial position that prevents fluid flow through the ports of the housing and second position that permits fluid flow through the ports. A bottom hole assembly may be connected to the sleeve by an anchor. A packer element may create a seal between the bottom hole assembly and the sleeve permitting a pressure differential across the packer element to move bottom hole assembly down the casing moving the sleeve to the second position. In the second position, the formation adjacent to the ported housing may be stimulated and/or treated.
