Abstract: A method for estimating values of well log measurements of a first selected type in wellbore sections wherein the measurements of the selected type are determined not to be valid includes establishing a linear relationship between measurements of a first selected type and measurements of a second selected type. The measurements of the second selected type are substantially valid over an entire measured axial section of the wellbore. Correct values of the measurements of the first type in the wellbore sections using measured values of the second type and the linear relationship.

Abstract: A method for selecting core points in subsurface formations includes selecting a zone from at least one subsurface formation. At least one statistical measure of at least one petrophysical measurement with respect to position along the selected zone is calculated. A predetermined number of core points at randomly selected positions along the selected zone is selected The at least one statistical measure is calculated for the randomly selected positions. Using a Monte Carlo iteration, the positions along the selected zone are randomly reselected and the at least one statistical measure is recalculated for the randomly reselected points until the at least one statistical measure for the randomly selected points is a maximum for a user selected statistical criterion applied to the at least one statistical measure of at least one petrophysical measurement with respect to position along the selected zone.
