Relative Permeability Gas Oil Calculator: Compute Corey gas-oil relative permeabilities from gas saturation with residual saturations, Corey exponents and endpoint values.
When to use Relative Permeability Gas Oil
Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.
- Sg
- Gas saturation as a fraction.
- Sgr
- Critical/residual gas saturation as a fraction.
- Sorg
- Residual oil saturation to gas as a fraction.
- krg end point
- Gas relative permeability endpoint krg°.
- kro end point
- Oil relative permeability endpoint kro°.
- ng
- Gas Corey exponent ng.
- no
- Oil Corey exponent no.
How Relative Permeability Gas Oil works
Compute Corey gas-oil relative permeabilities from gas saturation with residual saturations, Corey exponents and endpoint values. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Sg*
- Normalized gas saturation between zero and one.
- krg
- Gas relative permeability.
- kro
- Oil relative permeability.
Limitations and assumptions
- Petroleum correlations are fluid-, pressure-, temperature-, and region-dependent. PVT sampling, phase behavior, relative permeability, capillary pressure, heterogeneity, aquifer support, well constraints, history match, and units affect forecasts and reserves.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.
