VFM (SRP) Package

This package estimates the liquid production rate of wells equipped with sucker rod pumps (SRPs) pump data.

Usage

Run the workflows from this package to perform the calculations. The schedules may be adapted to use different contexts.

The script VFM Error Estimation can be used to estimate the error of the calculated values compared to measured data.

Details

The liquid production rate is calculated using pump data as:
