Electric submersible pump event detection

A system for monitoring operation of an electric submersible pump, comprising:

• a plurality of sensors configured to generate data indicative of a plurality of observable parameters regarding operation of the electric submersible pumping system;
• a processor coupled to the sensors configured to:
• receive the data from the sensors;
• establish, for at least some of the plurality of parameters, an associated reference signal;
• detect 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, update the value of the reference signal to reflect the deviation;
• and
• as a result of the deviation having a rate of change above the predetermined threshold, generate an indication of an event;
• wherein the indication of the event further depends on a type of the parameter and a direction of the deviation from the reference signal.

A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to:

• receive data indicative of a plurality of observable parameters from one or more sensors;
• establish, for at least some of the plurality of parameters, an associated reference signal;
• detect 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, update the value of the reference signal to reflect the deviation;
• and
• as a result of the deviation having a rate of change above the predetermined threshold, generate an indication of an event;
• wherein the indication of the event further depends on a type of the parameter and a direction of the deviation from the reference signal.
