Claim 9:
10. A bottomhole assembly, configured for coupling to a conveyance system for downhole deployment within a wellbore, wherein the conveyance system defines a fluid passage, comprising:
an uphole passage for disposition in flow communication with the fluid passage of the conveyance system while the bottomhole assembly is coupled to the conveyance system;
a downhole passage;
a valve for controlling flow communication between the uphole passage and the downhole passage; and
a wellbore tool; and
a clean-out flow communicator, disposed in flow communication with the downhole passage for discharging fluid, that is being conducted via the downhole passage externally of the bottomhole assembly, and for receiving fluid flow externally of the bottomhole assembly;, wherein:
the valve is configurable in at least a flow-through configuration and an actuation-facilitating configuration;
while the valve is disposed in the flow-through configuration:
bypass of the downhole passage, by fluid flow that is being conducted downhole via the uphole passage, is prevented, such that the fluid flow is conductible downhole, via the downhole passage, to the clean-out flow communicator; and
bypass of the uphole passage, by fluid flow that is being conducted uphole via the downhole passage from the clean-out flow communicator, is prevented, such that the fluid flow is conductible uphole, via the uphole passage;

and
while the valve is disposed in the actuation-facilitating condition, flow communication between the uphole passage and the downhole passage is sufficiently occluded with effect that the wellbore tool is responsive to a fluid pressure force, that is communicated via the fluid passage of the conveyance system, for effecting a hydraulically-actuated wellbore operation,
the valve being configurable from the flow-through configuration to the actuation-facilitating configuration, and further configurable from the actuation-facilitating configuration to the flow-through configuration.
