Executive Summary

Gasoline starts its journey as crude oil thousands of feet underground. Crude is a mix of thousands of hydrogen-carbon compounds ranging from gases to solids as well as sulfur and other materials. "Black gold" began forming millions of years ago as plant and animal remains decayed in sediments at the bottoms of oceans, lakes and streams. Massive pressures and temperatures converted this organic matter into oil and gas. In rare circumstances, rock formations trapped large accumulations of crude oil that can be extracted in commercial amounts.
