ABSTRACT:
A well pipe string joint locator for attachment to the end of a length of coiled tubing and moved within the pipe string as the coiled tubing is lowered or raised therein is provided as well as methods of using the joint locator. The joint locator is comprised of an elongated tubular housing having a longitudinal fluid flow passageway therethrough and having at least one lateral port extending through a side thereof. Electronic means are disposed within the housing for detecting the increased mass of a pipe joint as said locator is moved through the joint and generating a momentary electric output signal in response thereto. Valve means are disposed within the housing responsive to the electric signal for momentarily opening or closing the lateral port of the housing to thereby create a surface detectible pressure drop or rise.
