A non-pressure sensitive (“NPS”) module. The NPS module may include a mandrel, a lug assembly, a release sleeve, and a retention mechanism. The mandrel may have fluid pathways that balance pressure uphole of the mandrel and downhole of the mandrel when the NPS module is positioned within the borehole. The lug assembly may extend at least partially through the mandrel, a lug of the lug assembly extendable through a port in the liner hanger to prevent setting of the liner hanger when the lug assembly is in a run-in position. The release sleeve may be coupled to the lug assembly and operable to shift the lug assembly from a run-in position to an intermediate position that allows the liner hanger to be set. The retention mechanism may be operable to prevent the lug assembly from shifting to a retracted position until run-in tool is pulled uphole.
A non-pressure sensitive (“NPS”) module for use with a liner hanger installable within a borehole via a run-in tool, the NPS module comprising:
A liner hanger system for use in a borehole, the liner hanger system comprising:
A method of positioning a liner hanger within a well, the method comprising:
