Data compiled from 5300 sidewall core samples indicate that sidewall cores from low permeability formations have an indicated permeability greater than that determined from conventional core analysis. Sidewall cores from formations with more than 20 md permeability consistently have a measured permeability that is lower than that from conventional analysis. (After Craft and Keelan, 1985; data from Jenkins, 1987.)
