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.

kg

Measured gas permeability in millidarcies.

b

Klinkenberg slippage factor b in kilopascals.

Pm

Mean pore pressure in kilopascals.

Apply the Klinkenberg gas-slippage correction kL = kg / (1 + b/Pm) to a steady-state core gas measurement. 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]

kL

Klinkenberg-corrected liquid-equivalent permeability in millidarcies.

Correction

Dimensionless slip correction factor 1 + b/Pm.

• Aquifer calculations assume a geometry, boundary condition, flow regime, hydraulic properties, well construction, and observation response. Heterogeneity, anisotropy, leakage, storage, partial penetration, recharge, and pumping history can invalidate simple analytical solutions.
• 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.

Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.
