Fibercore offers a range of slickline fiber optic cables suitable for logging wells directly or to be incorporated into a coiled tube. The portfolio utilizes a fiber in metal tube to house and protect the optical fibers and to ensure that the excess fiber length is controlled appropriately. As with the permanent downhole fiber optic cables, these fibers can be used to sense temperature and listen to well bore activities along the entire length of the cable and can be used for telemetry to point fiber optic sensors, such as pressure sensors and strain sensors that are incorporated into a tool. This information provides key information to the reservoir engineer to better manage the well and the reservoir. Design variables include: type and number of optical fibers, metal types to deal with different corrosive environments and thicknesses of metal tubes to handle different pressure requirements.
