Patent ID: 7979240

Claim:
A method of monitoring an electrical submersible pump disposed downhole in a subterranean wellbore including: storing a plurality of first measurement values in a management system that comprises at least one computer, each first measurement value associated with one of a plurality of operating parameters of the electrical submersible pump, said plurality of first measurement values obtained during downhole operation of the electrical submersible pump over time; the management system being at least partially connected with the electrical submersible pump remotely by way of a data communications network; obtaining a plurality of user-supplied stable operating values corresponding to said plurality of operating parameters and inputting the user-supplier stable operation parameters to the management system; generating a failure prediction value with the management system by calculating a percentage change of the respective first measurement values and the corresponding user-supplied stable operating values, the failure prediction value representing likelihood of failure of the electrical submersible pump; and storing said failure prediction value in the management system for subsequent output and monitoring of the electrical submersible pump.
