Abstract

See full text

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.
