Abstract: A system and technique for obtaining two or more distributed measurements from an optical sensing fiber deployed along a desired measuring path are disclosed. Interrogating probes from two or more different distributed measuring systems are combined and launched into the sensing fiber. Backscattered light generated in response to the combined interrogating probes is separated into portions and each portion is provided to a respective distributed measuring instrument. In this manner, distributed measurements corresponding to different parameters of interest, such as temperature and pressure, along the measuring path can be measured simultaneously using the same sensing fiber.

Abstract: The disclosure relates to a method of evaluating characteristics of an earth formation, comprising deploying a packer assembly in a borehole penetrating an earth formation, the packer assembly comprising an instrumented inflatable packer element including fiber optic sensors; inflating the instrumented inflatable packer elements; detecting, using the fiber optic sensors, events occurring in the earth formation; and transmitting data corresponding to the detected events to a surface processing system. The disclosure also relates to a packer element and a instrumented packer assembly system. The disclosure may enable to derive formation characteristic in several configurations such as a stress test or a hydraulic fracturing configuration.

Abstract: A method includes running a cable into a first wellbore. A fluid diversion process is initiated in the first wellbore. A first downhole measurement is captured in the first wellbore using the cable or a first sensor coupled thereto concurrently with or after the fluid diversion process. An additional measurement is captured concurrently with capturing the first downhole measurement. The first downhole measurement and the additional measurement are compared or combined. A location where fluid is flowing through perforations in the first wellbore is determined based upon the combining or comparing the first downhole measurement and the additional measurement.

Abstract: A method can include, during a treatment process, receiving vibration data acquired over a length of a fiber cable sensor disposed in a well that includes perforations; filtering the vibration data as to traveling waves to generate filtered data; analyzing the filtered data to generate fluid flow information; and adjusting the treatment process based at least in part on the fluid flow information.

Abstract: A method, downhole tool, and system, of which the method includes deploying a perforation charge into a wellbore, signaling the perforation charge to detonate, deploying a cable into the wellbore, determining a fluid flow rate at a predetermined location in the wellbore using the cable, and determining whether the perforation charge detonated at the predetermined location based on the fluid flow rate.

Abstract: A method includes varying a temperature of a treatment fluid. The treatment fluid is pumped into the first wellbore as part of a fluid diversion process or a fluid treatment process after the temperature of the treatment fluid is varied. A first downhole measurement is obtained in the first wellbore using a cable in the first wellbore or a first sensor coupled to the cable concurrently with or after the fluid diversion process or the fluid treatment process. An additional measurement is obtained concurrently with obtaining the first downhole measurement. The first downhole measurement and the additional measurement are combined or compared. A location where the treatment fluid is flowing through perforations in the first wellbore is determined based upon the combining or comparing the first downhole measurement and the additional measurement.

Abstract: A technique facilitates monitoring of flow conditions with respect to flow through a tubing. A distributed sensor is routed along an interior of the tubing to monitor flow conditions. For example, the distributed sensor may be routed over a length of the tubing having a lateral opening. Fluid is flowed along the distributed sensor and within the interior of the tubing. The distributed sensor is operated to measure strain which results from flow of the fluid along the distributed sensor. The strain may then be evaluated to determine a change in a flow condition, such as a change in a flow condition related to the lateral opening.
