Patent ID: 8851175

Claim:
An instrumented tubular joint apparatus for use in a pipe string comprising: i. An upper tubular section with a threaded connection thereabove and an axial passage for fluid to flow through operatively connected to, ii. A lower tubular section with a threaded connection therebelow and an axial passage for fluid to flow through, iii. A sensor contained in the instrumented tubular joint to measure strain at the instrumented tubular joint, iv. A data recording and transmitting unit operatively connected to the sensor, v. A device to relay the data acquired by the sensor to a surface processing unit; vi. An extend and retract mechanism which extends against a borehole wall and retracts to loosen the instrumented tubular joint based on a signal received from the surface processing unit; vii. A plurality of circulating ports which are selectively opened to circulate fluid to loosen the instrumented tubular joint, the extend and retract mechanism and the plurality of circulating ports being located on at least one of the upper tubular section and the lower tubular section; and viii A mechanism to disconnect the upper tubular section from the lower tubular section after receiving a signal from the surface processing unit.
