Abstract:
Embodiments for determining a stuck pipe location include determining that a pipe is stuck in a wellbore due to an obstruction; deploying a fiber optic stuck pipe location detector inside the pipe, activating a first fiber optic sensor to detect a baseline reading, and manipulating the pipe. Some embodiments include detecting micro-noises caused by the stretching of the pipe, wirelessly acquiring data related to the micro-noises from the first fiber optic sensor, and determining a location of the obstruction by comparing the baseline reading with the data related to the micro-noises. Some embodiments include recovering the pipe at a predetermined point around the location of the obstruction while leaving the first fiber optic sensor inside the pipe.
