Characterizing Curvilinear Features Using the Localized Normal-Score Ensemble Kalman Filter

Table 1

Parameters defining the multiGaussian random function used to generate the log conductivities within each of the two facies.

Facies	Variogram type	Mean (ln(m/d))	Variance (ln(m/d)^2)	𝜆^∗𝑥 (m)	𝜆^∗𝑦 (m)
Sand	Exponential	2.1	0.7	144	72
Shale	Exponential	−1.4	0.7	72	72

∗Correlation ranges in the 𝑥 and 𝑦 directions.
