Abstract: A dual use cable includes at least one fiber optic cable encased in a metallic component that is encased in a layer of polymer material. The polymer material is surrounded by a tube or armor wire strength members embedded in one or two additional polymer material layers. A final assembly can include an outer metallic component or an outer layer of polymer material. The at least one fiber optic cable transmits data and the armor wire strength members and/or metallic components transmit at least one of electrical power and data.

Abstract: A sensing optical fiber includes multiple waveguides or cores to allow sensing of multiple measurands using a single fiber. The fiber can be a dual clad fiber having a single mode core and a multi-mode core disposed radially or circumferentially about the single mode core. A dual clad fiber coupler couples source light from a DAS interrogator and a DTS interrogator into the dual clad fiber in use.

Abstract: Systems and methods for monitoring and control in downhole well applications are provided. The system and methodology may be combined with a variety of completions or other types of well equipment deployed downhole to enable both electrical and fiber optic communication with downhole components. For example, the system enables both electrical and fiber optic communication for operating and monitoring of downhole completion systems or other systems.
