Predictive Maintenance · ESP

ESP failures. Caught days early.

One unplanned ESP failure on a 500 BO/d well costs $200K-1M+ all-in. Per-well ML on motor amps, intake pressure, and vibration catches bearing wear, motor-temp drift, and gas locking days before fixed-threshold SCADA would. One deferred failure pays for the annual license.

Four ESP signatures.

Signature

Bearing wear

ML detects

Vibration creeping above per-unit historical envelope

Root cause

Sand, gas slug, alignment, mechanical wear

Action

Schedule pull at 7-14 day window; not after motor seizure

Signature

Motor temperature drift

ML detects

Motor temp creeping above historical envelope

Root cause

Coolant flow loss, intake gas, downhole motor cavity gas

Action

Investigate intake first; motor pull only if downhole cooling confirmed lost

Signature

Gas locking

ML detects

Intake pressure spiking + discharge pressure falling

Root cause

GOR increase, packer leak, formation gas breakthrough

Action

Cycle VSD; investigate gas source; consider gas separator

Signature

Motor amp drift

ML detects

Amps rising at constant frequency

Root cause

Scale, bearing wear, increased fluid viscosity

Action

Chemical or pull window depends on root cause; ML attribution narrows it

Frequently asked

What production foremen ask about ESP ML.

What ESP failures does WorkSync detect?

Bearing wear (vibration), motor temp drift, gas locking (intake-pressure spike + discharge fall), motor-amp drift at constant frequency. Each flagged days before fixed SCADA thresholds.

Cost of an ESP failure?

Replacement $50-200K + emergency rig premium. Deferred production $20-80K/day. Total exposure on unplanned failure $200K-1M+.

Lead time vs SCADA?

Vibration: 3-14 days advance. Motor-temp drift: 1-7 days. Gas locking catches event before well stops producing.

What data?

Motor amps, intake/discharge pressure, motor temperature, vibration. From Schlumberger Lift IQ, Baker Centrilift, Borets, standard ESP VSD telemetry.

ROI math?

One ESP failure caught 7 days early on a 500 BO/d well saves ~$280K deferred production + $100K+ rig premium. Annual license pays for itself on a single deferred failure.
