Permeability LAMBDAs
Carothers sandstone permeability from the formation factor.
1 lambda
PO.PP.Perm.Carothers.Sandstone(F)
Sandstone permeability from the formation factor, the correlation Carothers published in 1968. It is a statistical fit, not a pore-scale derivation, and it applies to sandstones. The limestone fit is a different equation and is not this one. k = 7×10^8 / F^4.5, with k in millidarcies and F dimensionless.
