Description
Gas well deliverability analysis comparing Darcy flow (low rate) with non-Darcy flow that includes turbulence effects at high rates. The non-Darcy coefficient D accounts for inertial resistance near the wellbore.
Parameters:
- Pres: Reservoir pressure (psia)
- k: Permeability (md)
- h: Net pay thickness (ft)
- T: Temperature (°R)
- D: Non-Darcy coefficient (1/Mscf/d)
