Predictive Maintenance · Rod Pump

Rod pump failures. Caught 24–72 hours early.

Per-well dynamometer ML detects pump fillage degradation, gas interference, parted rod, and fluid pound. Each signature flagged before the production rate moves enough to cross a fixed SCADA threshold. Workover avoidance ($15-30K) plus deferred production recovery ($5-15K/day) is the math that justifies the annual license.

Four rod-pump signatures.

Signature

Pump fillage degradation

ML detects

Card area shrinking >15% over 7 days

Root cause

Wear, gas interference, formation issue

Action

Schedule pump pull at 14-21 days, not after parted-rod event

Signature

Gas interference

ML detects

Card shape: filled → gas-interfered at top-of-stroke

Root cause

GOR increase, separator failure, formation gas breakthrough

Action

Investigate separator before scheduling pump work

Signature

Parted rod

ML detects

Sudden bottom-load drop with maintained top-load

Root cause

Rod failure, typically at coupling or transition joint

Action

Pull immediately; production at risk every hour

Signature

Fluid pound

ML detects

Characteristic late-stroke spike pattern

Root cause

Pump-off / over-pumping (rate exceeds inflow)

Action

Adjust SPM via controller before mechanical damage compounds

Frequently asked

What rod-pump foremen ask.

What rod pump failures does WorkSync detect?

Pump fillage degradation, gas interference, parted rod, fluid pound. Each flagged with dollar-impact + intervention cost + ranked into the work plan.

What is the lead time vs fixed SCADA?

24-72 hours advance warning. Card-shape signatures change before production rate does. ~$3,750/day avoided deferred production at 50 BO/d, $75/bbl.

Workover math?

Reactive workover $15-30K + 24-72hr deferred production at $5-15K/day. Scheduled catch 48hrs pre-failure: same workover cost, near-zero deferred, no emergency rig premium.

What data does it need?

Dyno cards from pump-off controller, production rate from SCADA/run tickets, well-test data. Trains on 90-180 days of historical card data per well.

Pump-off controller brands?

Lufkin SAM, Weatherford WellPilot, eProduction, Theta SmartCard. Any controller exporting standard dyno card formats.
