/Downhole Fiber Optic Cable Designed With Improved Strain Response And Designed For Long Life In The Well
Abstract
Implementations of an apparatus, a system, and a method are disclosed herein. In one implementation, an apparatus comprises an optical fiber cable configured for use in a wellbore proximate to one or more subsurface formations, wherein the optical fiber cable is configured to attach to a supporting structure in the wellbore, wherein the optical fiber cable includes one or more optical fibers configured in a state of axial compression at room temperature, and wherein the one or more optical fibers are configured to remain in the state of axial compression during a thermal expansion of the supporting structure in the wellbore.
