Apparatus having a fiber optic tether disposed in coiled tubing for
communicating information between downhole tools and sensors and surface
equipment and methods of operating such equipment. Wellbore operations
performed using the fiber optic enabled coiled tubing apparatus includes
transmitting control signals from the surface equipment to the downhole
equipment over the fiber optic tether, transmitting information gathered
from at least one downhole sensor to the surface equipment over the fiber
optic tether, or collecting information by measuring an optical property
observed on the fiber optic tether. The downhole tools or sensors
connected to the fiber optic tether may either include devices that
manipulate or respond to optical signal directly or tools or sensors that
operate according to conventional principles.
