Rod Pump Production
Calculate theoretical pump displacement and production rates
The Rod Pump Production calculator determines theoretical production rates based on pump geometry, stroke length, and pumping speed.

Outputs
Results Table
For each crank hole position, shows:
- SPM for target production - Required SPM to achieve desired bbl/day
- Production at target SPM - Expected production at desired SPM
