Abstract

A method for mud logging includes making first gas measurements of a first gas sample obtained from circulating drilling fluid on a drill rig using a first gas chain; making second gas measurements of a second gas sample obtained from circulating drilling fluid on a drill rig using a second gas chain; defining a quality control window for the first gas measurements from the second gas measurements; and cross quality controlling the first and second gas measurements by comparing the first gas measurements with the quality control window.
