Abstract: Aspects of the disclosure include an optical fiber sensing system and apparatus that provide for free rotation of fiber optic cables containing multiple cores. For example, the disclosure presents a fiber optic rotary joint, comprising a stator housing a non-rotating portion of a dual-core fiber optic cable and a rotor housing a rotating portion of the dual-core fiber optic cable. In such an example, the rotor is mounted to the stator to allow rotation of at least a portion of the rotor about at least a portion of the stator. Further provided is an optical fiber sensing system, comprising one or more multiplexor/demultiplexors configured to multiplex and demultiplex one or more signals, a dual-core fiber optic cable communicatively coupled to the multiplexor/demultiplexor and configured to carry one or more signals on an inner core and an outer core disposed about the inner core, and a dual-core fiber optic rotary joint.

Abstract: A subsurface electric field monitoring system includes one or more electric field sensors deployed external to a casing in a borehole formed in a downhole formation. The system also includes a multi-layer cement arrangement external to the casing, where the multi-layer cement arrangement focuses emitted current to a target region of the downhole formation. The system also includes a data processing system that receives measurements collected by the one or more electric field sensors in response to the focused emitted current, wherein the data processing system models the subsurface electric field based on the received measurements.

Abstract: A method for using the depth derivative of distributed temperature sensing data to identify fluid levels, gas production intervals, water production intervals, and other fluid flow activities inside or near the well-bore during the production process comprises providing a fiber optic based distributed temperature sensing measurement system through a production region; gathering the temperatures through the production region as a function of the depth in the subsurface well and as a function of the elapsed time; calculating from the gathered data the depth derivative of the temperature changes as a function of depth in the subsurface well and of the elapsed time; and displaying the depth derivative data for analysis of the fluid levels by operators to identify fluid levels, gas production intervals, water production intervals, and other fluid flow activities inside or near the wellbore during the production process.

Abstract: A method of monitoring a flood front. The method may comprise installing at least one optical electromagnetic sensor in a wellbore which penetrates an earth formation. The sensor may be a part of an interferometer selected from the group consisting of a Mach Zehnder interferometer and a Michelson interferometer. The method may further comprise inducing an electromagnetic field in the earth formation. A first optical path length in a first optical waveguide of the sensor may increases in response to exposure to the electromagnetic field, and a second optical path length in a second optical waveguide of the sensor may decreases in response to exposure to the electromagnetic field. Additionally, the method may comprise monitoring the flood front by detecting via the sensor the electromagnetic field in the earth formation as the flood front progresses through the earth formation.
