Simulation Comparisons
Compare up to five rod pump simulation designs side-by-side in PetroBench. Evaluate rod strings, loads, production rates, and equipment configurations.
Compare up to 5 rod simulations with different configurations to identify the optimal design.
Create a Comparison
- Navigate to your well's RodSim tab
- Select two or more simulations using checkboxes
- Click Compare
- Review the auto-generated name and description
- Click Create Comparison
The first simulation becomes the base simulation - your reference point. It always appears first and can't be deleted.
Add & Manage Simulations
Add a Scenario
Click Add Scenario to add another scenario. It's created as a duplicate of the base case, which you then edit.
Delete a Scenario
Click the trash icon on a scenario card to remove it. The base scenario can't be deleted.
Configure Each Scenario
Expand a scenario card to modify:
- Pumping Unit - Select different units per scenario
- Rod String - Modify grades, sizes, taper sections
- Tubing - Adjust anchor settings, pump depth
- Parameters - Set stroke rate, production targets
Run the Comparison
- Click Run Comparison
- Monitor progress for each scenario
- Wait for all scenarios to complete
Scenarios run sequentially (base simulation first). Each typically takes 10-30 seconds.
If a scenario fails, others continue processing. Failed scenarios show error messages in results.
View Results
The results page shows side-by-side metrics:
| Metric | Description |
|---|---|
| Max / Average Rod Loading (%) | Peak and average rod loading vs limit |
| Gearbox Loading (%) | Gearbox loading vs rating |
| Structural Loading (%) | Unit structural loading vs rating |
| Fluid Production | Produced fluid rate |
| SPM | Strokes per minute |
| PPRL / MPRL | Peak and minimum polished rod load |
| Pump Diameter / Stroke Length / Gross Pump Stroke | Pump and stroke geometry |
| Manufacturer / Model | The pumping unit |
Values outside recommended ranges are highlighted.
Re-Running
After modifying scenario configurations:
- Return to Comparison Inputs
- Make changes to any scenario
- Click Run Comparison
Re-running overwrites previous results for all scenarios.
