Abstract
A wellbore drilling system utilizes optical fibers to measure parameters of interest and to communicate data. One or more electrical conductors are used to provide power to the components of the drilling system. The acquisition electronics for operating fiber optic sensors can be positioned at the surface and/or in the wellbore. In some embodiments, one optical fiber includes a plurality of sensors, each of which can measure the same or different parameters. A multiplexer multiplexes optical signals to operate such sensor configurations. Optical fiber sensors for acoustic measurements can include a cylindrical member wrapped by one or more optical fibers. The sensors can be configured as needed to provide a 3D representation of the pressure measurements.
