How to Use This Calculator
- Enter reservoir permeability (md), formation thickness (ft), and target fracture half-length (ft).
- Enter fracture conductivity (md-ft) and wellbore radius (ft).
- Read dimensionless fracture conductivity (CfD) and estimated folds of increase (FOI) in productivity.
- Review optimal proppant volume and pump rate recommendations.
- Compare pre-frac vs. post-frac productivity index to evaluate stimulation effectiveness.
How the result changes with Lateral Length
| Lateral Length | Number of Stages | Total Fluid |
|---|---|---|
| 2,900 | 14 | 112,000 bbl |
| 7,650 | 38 | 304,000 bbl |
| 13,350 | 66 | 528,000 bbl |
| 18,100 | 90 | 720,000 bbl |
What each input means
- Lateral Length
- Horizontal lateral length of the well.
- Stage Spacing
- Distance between fracturing stages.
- Clusters per Stage
- Number of perforation clusters per stage.
- Fluid per Stage
- Slurry volume pumped per stage.
- Proppant per Cluster
- Proppant weight per perforation cluster.
- Pump Rate
- Average pumping rate during the frac job.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersLateral Length = 10000, Stage Spacing = 200, Clusters per Stage = 4, Fluid per Stage = 8000 = 6 input(s) provided
- Calculate Number of StagesNumber of Stages50 = 50
- Calculate Total FluidTotal Fluid400000 = 400000
- Calculate Total ProppantTotal Proppant7500 = 7500
- Calculate Total Pump TimeTotal Pump Time83.3 = 83.3
