How to Use This Calculator
  1. Enter reservoir permeability (md), formation thickness (ft), and target fracture half-length (ft).
  2. Enter fracture conductivity (md-ft) and wellbore radius (ft).
  3. Read dimensionless fracture conductivity (CfD) and estimated folds of increase (FOI) in productivity.
  4. Review optimal proppant volume and pump rate recommendations.
  5. Compare pre-frac vs. post-frac productivity index to evaluate stimulation effectiveness.
