The invention relates to techniques, such as a system for generating a density of a cased wellbore. The system includes at least one downhole tool deployable into the cased wellbore, a radiation source supportable by the downhole tool for passing radiation through the subterranean formation, at least one detector supportable by the downhole tool for measuring the radiation, and a measurement tool for generating at least one apparent density log from the measured radiation. The measurement tool has at least one quality indicator tool for generating at least one quality indicator and for generating at least one compensated density log based on the apparent density log and the quality indicator whereby error is removed therefrom.
