Sucker Rod Pump Card Analysis
In one sentence
Reads the dynamometer card automatically and names the downhole condition — gas interference, fluid pound, worn valve, parted rod.
The problem
Card interpretation is a specialist skill applied to a sample of wells a few times a year. On a field of several hundred beam-pumped wells, most cards are never looked at and problems run for months.
How it works
Surface cards are converted to downhole cards through the wave equation, then a classifier trained on labelled card shapes identifies the condition and the pump fillage. Because the physics step is explicit, the classifier operates on a normalised representation and transfers between fields far better than a model trained on raw surface cards.
Data required
- Surface dynamometer cards, ideally at least daily per well
- Rod string design, pump specification and setting depth
- Fluid properties and tubing anchor status
- Labelled historical cards or pull reports for validation
What you get
- Automatic card classification and pump fillage per well per day
- Alerts for fluid pound, gas interference, valve leak and rod failure
- Pump-off controller setpoint recommendations
What it cannot do
Downhole card conversion depends on an accurate rod string description and damping factor. Where the rod tally in the records does not match what is actually in the well — which is common after several workovers — the converted card is distorted and classification confidence drops. The system flags wells where the computed card is physically inconsistent rather than classifying them anyway.
Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
