The petroleum system concept is a reliable and logical way to judge and describe the petroleum potential and exploration risks of undrilled propects, plays, and basins. In 19 chapters on petroleum system basics and 18 case study chapters, this comprehensive volume provides an integrated look at the processes of petroleum generation in active source rocks, migration, and accumulation in traps.

Cataloging-in-Publication data is on fi le with the Library of Congress FRONT COVER Photograph of pump unit atop an oil well in Los Gatos, Calif. The pump unit and well are in a fenced enclosure in the parking lot of a commercial offi ce building on Los Gatos Boulevard near Garden Lane. According to the current owner, the well has not produced oil for many years, but unconfi rmed reports suggest that the well yielded about 8 barrels of oil per day in 1953. Geologic and organic-geochemical information from this and other historical oil wells in the Los Gatos area provide important insights into the subsurface geology and geologic history of the southwestern Santa Clara Valley ("Silicon Valley"); see text for further discussion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
