1. A bottom hole assembly for use within a borehole that extends from surface into a subterranean formation, comprising:
a resettable plug, an actuator tool, a gripping tool, a power tool and a locating tool;
wherein the resettable plug may be activated and deactivated at one or more locations within the borehole without removal from the borehole;
the resettable plug including a central body, a selectively deployable sealing element about a periphery of the central body, and a fluid passageway that extends through the central body from at least one first opening in the central body on a first side of the deployable sealing element to at least one second opening in the central body on a second side of the deployable sealing element;
a valve disposed to control fluid flow through the fluid passageway;
a pressure sensor secured to sense fluid pressure within the borehole on the first side of the deployable sealing element;
a valve actuator coupled to the valve for controlling operation of the valve;
the at least one first opening in fluid communication with the surface via only the borehole on the first side of the deployable sealing element and via the fluid passageway, the at least one second opening on the second side of the deployable sealing element; and
the at least one second opening in fluid communication with the borehole on the second side of the deployable sealing element, the borehole below the bottom hole assembly and via the fluid passageway, the at least one first opening on the first side of the deployable sealing element.
