Modeling assumptions
PKN-flavoured half-length scaling L ∝ (V·q / (E·h²))^(1/4) with SRV height growth from net pressure.
Assumed
- Single planar fracture per stage; SRV width ≈ 0.18 × half-length (Barnett complex network).
- SRV height capped at 1.6 × pay; grows weakly with net pressure (0.038 ft / psi).
- Constants fitted once against Fisher et al. P50 reports — no per-stage retune.
- Slurry and rate enter via energy proxy V·q; viscosity and proppant loading not resolved.
Out of scope
- Stress shadow / parent-child interference
- Natural fracture branching and proppant transport
- Microseismic moment-tensor inversion
