Advanced gas-in-mud analysis puts reservoir in sharper focus

HOUSTON -- Halliburton has introduced the GasFact service to deliver continuous real-time gas-in-mud analysis at the wellsite.

Halliburton’s GasFact service employs the EAGLE gas extraction system and the Dq1000 mass spectrometry gas analyzer to overcome limitations of conventional extraction systems, and to provide analyses that are far superior to other available mud logging technologies in the market.

Combined with geological sampling and drilling parameter observations, timely mud gas analysis can improve reservoir understanding and inform real-time drilling decisions to avoid nonproductive time in a range of applications.

The EAGLE system addresses deficiencies of conventional gas traps with a design that extracts a consistent fixed-volume mud sample, prevents contamination of gas-in-air measurements, and ensures a constant degassing temperature that makes it possible to extract heavy hydrocarbons, even in deepwater environments where returns are typically cooled.

The GasFact service then analyzes the high-quality samples using the Dq1000 mass spectrometer, which offers unmatched wellsite analysis capabilities, including effective measurement of more than 40 compounds and less than two-minute cycle times between scans.

In executing the GasFact service, Halliburton’s highly trained geologists employ Gas Analysis Studio™ software, which provides the rapid and flexible data manipulation required for real-time interpretation of reservoir features as well as improved estimates of petroleum type and quality.

The GasFact service is offered at a number of service levels, and the EAGLE extraction system and Dq1000 spectrometer can be used separately with conventional equipment.
