Abstract
Methods, systems, and computer program products for correcting cased hole neutron porosity logs provide a 'residual' correction that substantially accounts for potential coupling between casing thickness and other environmental parameters. The residual correction may be used to derive a casing thickness response function that is customized for the particular well under consideration. The customized casing thickness response function may then be used to adjust cased hole neutron porosity logs for the well in a manner that more accurately accounts for potential coupling of the effects of casing thickness and other environmental parameters, in contrast to existing solutions that tend to ignore such potential coupling.
