  • Calculation Guide
  • Overview
    • The pressure above which the fluid essentially remains in the liquid phase and all volatile components are dissolved in the liquid.
  • Equations
    • Standing Correlation
    • Pb = 18.2[(Rs/Sg) 0.83 10 a - 1.4
    • a = 0.00091 (T) - 0.0125 Sapi
    • --------------------------------------------------
    • Pb - Bubble Point Pressure (psi)
    • Rs - gas solubility at bubble point (scf/stb)
    • Sg - Specific Gravity of Gas under surface conditions
    • T - Reservoir temperature (deg.F)
    • Sapi - Oil API Gravity
