Monitoring An Electric Submersible Pump For Failures
First Claim
1. A method for monitoring an electric submersible pump, comprising:
- acquiring a baseline signature for the electric submersible pump in a first environment while the electric submersible pump is confirmed to be healthy;
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 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.

8. A system for monitoring an electric submersible pump, the system comprising:
-
a vibration sensor coupled to the electric submersible pump to measure a vibration signature of the electric submersible pump; and a processor coupled to the vibration sensor to; receive the vibration signature for the electric submersible pump in a downhole environment from the vibration sensor and while the electric submersible pump is in an operating mode; remove a downhole noise component from the vibration signature to produce an isolated electric submersible pump signature, wherein the downhole noise component is determined by applying an operator to a baseline signature for the electric submersible pump in a non-downhole environment and a downhole signature for the electric submersible pump in the downhole environment while the electric submersible pump is confirmed to be healthy; and determine a health status of the electric submersible pump based on the isolated electric submersible pump signature. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to:
-
receive a vibration signature for an electric submersible pump in a downhole environment from a vibration sensor and while the electric submersible pump is in an operating mode; remove a downhole noise component from the vibration signature to produce an isolated electric submersible pump signature, wherein the downhole noise component is determined by applying an operator to a baseline signature for the electric submersible pump in a non-downhole environment and a downhole signature for the electric submersible pump in the downhole environment while the electric submersible pump is confirmed to be healthy; and determine a health status of the electric submersible pump based on the isolated electric submersible pump signature. - View Dependent Claims (16, 17, 18, 19, 20)
