摘要:
Fiber optic enabled casing collar locator systems and methods include a wireline sonde or a coil tubing sonde apparatus configured to be conveyed through a casing string by a fiber optic cable. The sonde includes at least one permanent magnet producing a magnetic field that changes in response to passing a collar in the casing string, a coil that receives at least a portion of the magnetic field and provides an electrical signal in response to the changes in the magnetic field, and a light source that responds to the electrical signal to communicate light along an optical fiber to indicate passing collars.
