Origin of Non-Hydrocarbon Gases in Petroleum Reservoirs Origin of Problematic Non-Hydrocarbon Gases


This course provides a primer on the origin of problematic non-hydrocarbon gases in petroleum reservoirs, specifically hydrogen sulfide, carbon dioxide, and nitrogen. Emphasis is on using integrated petroleum geochemical and geological techniques, especially stable isotopes, noble gases, and petrology to characterize and interpret the generation and accumulation of H2S, CO2, and N2 within a petroleum systems context. The presentation provides both the necessary theoretical background needed to understand the material and specific case studies that illustrate how geoscientists and engineers can determine the origin of non-hydrocarbon gases in conventional and unconventional plays.

The course includes material for one full day of independent study.

Since its founding in 1917, the American Association of Petroleum Geologists has been a pillar of the worldwide scientific community. The original purpose of AAPG, to foster scientific research, to advance the science of geology, to promote technology, and to inspire high professional conduct, still guides the Association today.

AAPG provides publications, conferences, and educational opportunities to geoscientists and disseminates the most current geological information available to the general public.

As the world’s premier professional association for explorationists, AAPG is about the science of petroleum geology.

It’s also about the people.

AAPG’s membership is made up of more than 40,000 members in 129 countries in the upstream energy industry who collaborate – and compete – to provide the means for humankind to thrive.

AAPG provides the network of communications that allow those professionals to succeed.

We invite you to see who we are, what we are about and to contact us for membership information or details about the many services we provide.
