PKN Fracture Geometry Analysis
Description
Calculate PKN (Perkins-Kern-Nordgren) fracture geometry for vertically confined fractures.
Key Considerations:
- PKN model applies when fracture height is much less than length (Hf << Lf)
- Assumes elliptical cross-section with plane strain in vertical planes
- Valid for Newtonian fluids in laminar flow
- No fluid loss version assumes early time (t_D < 0.01)
