ABSTRACT:
Embodiments of methods and systems for detecting conditions inside a wellbore according to the invention are disclosed. One embodiment of the invention of the system includes a pipe (150) that is configured to rotate in a wellbore (140). A first detector (120) is located near the surface and is configured to measure a first parameter that correlates to rotation of the pipe (150). A second detector (160C) is located at a first depth away from the surface and is configured to measure a second parameter that correlates to rotation of the pipe (150). A circuit (130) is coupled to the first detector (120) and the second detector (160C) and is configured to compare the first and second parameters.
