... to be in the millidarcies range (Harpalani, 2006). The values estimated for samples 1 and 2, as presented table 1, are in the millidarcies range. However, samples 3 and 4 report significantly lower permeability values, in the micro/nano- darcy range. Given the low permeability for these two samples, values for step-wise...
