1. A system for detecting a downhole condition in a wellbore during a non-drilling wellbore operation, the system comprising:
- a tool string to be disposed within a wellbore;
a workpiece within the tool string for performing a non-drilling wellbore operation within the wellbore; and
a condition sensing tool within the tool string for sensing a downhole condition.

Abstract
Methods and devices for sensing operating conditions associated with downhole, non-drilling operations, including, fishing and retrieval operations as well as underreaming or casing cutting operations and the like. A condition sensing device is used to measure downhole operating parameters, including, for example, torque, tension, compression, direction of rotation and rate of rotation. The operating parameter information is then used to perform the downhole operation more effectively.

11. A condition sensing tool for use within a wellbore during a non-drilling operation to detect at least one downhole condition within the wellbore, the condition sensing tool comprising:
-
an outer housing defining an axial fluid flowbore therethrough;
a sensor section defined within the housing; and
at least one sensor for detecting at least one non-drilling downhole condition from the set of conditions consisting essentially of torque, weight, tool string compression, tool string tension, speed of tool string rotation, vibration, and direction of tool string rotation. - View Dependent Claims (12, 13)
