  • Publication number: 20170363088
    Abstract: A method for monitoring operation of an electric submersible pump. The method includes receiving data signals indicating values for a plurality of parameters regarding operation of the electric submersible pumping system; establishing, for at least some of the plurality of parameters, an associated reference signal; and detecting a deviation of one of the parameters from the reference signal associated with that parameter. As a result of the deviation having a rate of change below a predetermined threshold, the method includes updating the value of the reference signal to reflect the deviation. As a result of the deviation having a rate of change above the predetermined threshold, the method includes detecting an event and generating an indication of the event. The indication of the event further depends on a type of the parameter and a direction of the deviation from the reference signal.

  • Publication number: 20170356286
    Abstract: A leak-detecting assembly can include an array of hydrophones. The array can be moved within a hydrocarbon well. A variation in the Doppler shift caused by a stationary acoustic source (such as a leak) while the array moves towards and away from that source can be determined based on information from the array of hydrophones. The assembly can be associated with a passive system that captures acoustic signals directly from the source or leak and estimates a location of the source or leak based on measurement of Doppler shift in each receiver.

  • Patent number: 9716618
    Abstract: A scheduler may run a script. The script may have a plurality of configuration commands for a network device. A first configuration command of the plurality of configuration commands may be called to begin. A script engine may determine whether a termination request has been received. The script engine may run the first configuration command when it is determined the termination request is not received. While the first configuration command is running, the script engine may receive the termination request. Instead of terminating immediately upon detection of a termination request, the first configuration command may complete.
