Gas Referencing ™

Gas Referencing ™ is a proprietary standard for measuring and analyzing formation gas in the drilling fluid. A non-indigenous gas such as propylene is injected into the drilling fluid to create a Reference Gas with a known concentration. Upon returning to the surface, the Reference is used to: normalize gas measurements, monitor measurement system performance and measure lag.
