ABSTRACT:
Actuation of downhole tools is accomplished by inducing motion in the wireline. The downhole tool monitors such motion for predetermined patterns. Detection of a predetermined pattern actuates performance of a desired function. The pattern selected is sufficiently unique to avoid random or premature actuation. The tool may thus be actuated using ordinary nonconducting cable. In like fashion the tool can transmit stored information to the surface by a mechanical means such the resonant frequency of a mechanical signal in the cable.
