Allison and B. Mandler for AGI, 2018 Foreword The American Geosciences Institute (AGI) represents and serves the geoscience community by pro- viding collaborative leadership and information to connect Earth, science, and people. In 2003, AGI, in cooperation with our member societies and several federal agencies, released a publication called Petroleum and the Environment to give the general public, educators, and policy makers a better under- standing of environmental concerns related to petroleum resources. In the years that followed, the shale boom yielded a huge increase in domestic energy production, which came with new environmental challenges, opportunities, and uncertainties. We realized that our 2003 publication no longer provided the breadth or depth of information needed to understand how today’s oil and gas operations interact with the environment. This update to the original Petroleum and the Environment provides a completely rewritten overview of many environmental considerations associated with current practices as of 2018 in oil and gas explo- ration, production, processing, refining, transportation, and use. Designed as a series of factsheets that can be read individually or as a single publication, online or in print, this update is an accessible and impartial explanation of a complex subject. It can serve as a starting point for someone interested in learning more about petroleum and the environment, or as a reference work. We gratefully acknowledge funding from the American Association of Petroleum Geologists Founda- tion, which made this publication possible. I would also like to recognize Edie Allison, an experienced petroleum geologist and writer, and Ben Mandler, from AGI, who collaborated to write and produce this revised version of Petroleum and the Environment.

Allison and B. Mandler for AGI, 2018 Foreword For more than fifty years the American Association of Petroleum Geologists (AAPG) Foundation has focused on advancing the science of geology, particularly petroleum geology, by supporting educa- tional and research programs to benefit the geoscience profession and the public. Petroleum, both oil and natural gas, form the base of our energy infrastructure, which provides the foundation for modern society. There is a strong correlation between energy consumption and eco- nomic growth. And as nations seek to provide better lives for their citizens and coming generations, it’s essential that they have access to affordable, reliable energy supplies developed and produced in an environmentally-responsible manner. The AAPG Foundation is pleased to support this publication by the American Gesociences Institute that seeks to enhance public understanding of petroleum resources and their relation to environmental, human, and societal health.
