Abstract: A method for monitoring an electric submersible pump. The method includes acquiring a baseline signature for the electric submersible pump in a first environment, acquiring a downhole signature for the electric submersible pump in a downhole environment while the electric submersible pump is confirmed to be healthy, applying an operator to the baseline signature and the downhole signature that results in a downhole noise component, acquiring a vibration signature for the electric submersible pump in the downhole environment while the electric submersible pump is in an operating mode, removing the downhole noise component from the vibration signature to produce an isolated electric submersible pump signature, and determining a health status of the electric submersible pump based on the isolated electric submersible pump signature.

Abstract: A seismic survey system for performing offset borehole seismic survey measurement operations. The system may include a first seismic survey subsystem having a first wireless digital communication device and a second seismic survey subsystem having a second wireless digital communication device and remotely located from the first seismic survey subsystem. The first and second digital communication devices may be configured to provide a digital communication link for transporting digital information between the first seismic survey subsystem and second seismic survey subsystem. The system may be configured to enable a user at the first seismic survey subsystem to remotely modify at least a portion of a first plurality of operating parameters associated with at least one source signal device located at the second seismic survey subsystem. The system may also be configured to utilize GPS information in order to improve accuracy of source signal firing timing synchronization.
