<p>A method of locating a wellbore feature, comprising delivering a mechanical position determination tool (100) into the wellbore, selectively causing an undulating curvature (110, 112, 114) of the mechanical position determination tool in response to a change in a fluid pressure, moving the mechanical position determination tool (100) along a longitudinal length of the wellbore, and sensing a change in resistance to continued movement of the mechanical position determination tool. A mechanical position location tool (100) for a wellbore, comprising pressure actuated elements configured to cooperate to selectively provide an unactuated state in which the mechanical position location tool lies substantially along a longitudinal axis (102) and the pressure actuated elements further configured to cooperate to selectively lie increasingly deviated from the longitudinal axis (102) in response to a change in pressure applied to the mechanical position location tool.</p> |
