    Abstract: Various embodiments include methods and systems structured to transmit data from downhole sensors to the surface at a well site. The transmission can be implemented to overcome downhole connections that can act as obstructions to direct electrical and optical communication in a wellbore. Electrical signals from one or more sensors in a sensor unit, located on a side of a downhole connection in a wellbore opposite the surface of the wellbore, can be used to drive an acoustic transmitter to transmit an acoustic signal via a production string or casing or fluid in the production string or casing across the downhole connection, where the acoustic signal is received on the surface side of the downhole connection. Data correlated to the received acoustic signal can be provided to a surface location of the wellbore. Additional apparatus, systems, and methods can be implemented in a variety of applications.

    Abstract: A downhole optical sensing system can include an optical fiber positioned in the well, the optical fiber including multiple cores, and at least one well parameter being sensed in response to light being transmitted via at least one of the multiple cores in the well. The multiple cores can include a single mode core surrounded by a multiple mode core. A method of sensing at least one well parameter in a subterranean well can include transmitting light via at least one of multiple cores of an optical fiber in the well, the at least one of the multiple cores being optically coupled to a sensor in the well, and/or the at least one of the multiple cores comprising a sensor in the well, and determining the at least one well parameter based on the transmitted light.

    IPC: G05B19/416

    Abstract: A method of controlling a pumping sequence of a fracturing fleet at a wellsite. A managing application executing on a computer in the control van can retrieve the pumping sequence from a local or remote storage computer. The managing application can establish an electronic communication link to receive sensor data from a plurality of fracturing units. The managing application can control the plurality of fracturing units with a stage script with multiple sequential instructions for a pumping stage of a pumping sequence while receiving one or more periodic data sets from the plurality of fracturing units wherein the data sets are indicative of the current state of the pumping stage of the pumping sequence.

    Abstract: Systems and methods for distributed acoustic sensing based on coherent Rayleigh scattering are disclosed herein. A system comprises a pulse generator, optical fibers coupled to the pulse generator, an interferometer coupled to the optical fibers, a photodetector assembly coupled to the interferometer, and an information handling system configured to detect a difference in backscattered light from the optical fibers. A method comprises sending an optical pulses down optical fibers, receiving backscattered light from the optical pulses, combining the backscattered light from the optical pulses to form an interferometric signal, receiving the interferometric signal at a photodetector assembly, and determining a difference in the interferometric signal at an information handling system.
