Description
Injection gas pressure profile calculations. Determines gas gradient in the annulus and calculates injection pressure at various depths for gas lift system design.
Parameters:
- Ps: Surface injection pressure (psi)
- SG: Gas specific gravity (air = 1.0)
- P_avg: Average pressure (psi)
- T_avg: Average temperature (degR)
- Z: Gas compressibility factor
