Testing Gassmann fluid substitution: sonic logs versus ultrasonic core measurements
Although Gassmann fluid substitution is standard practice for time-lapse studies, its validity in the field environment rests upon a number of underlying assumptions. The impact of violation on the predictions of Gassmann equations can only ultimately be validated by in situ testing in real geologic...
