   abstract: Paul Lillis is a recently retired petroleum geochemistwith the Central
     Energy Resources Science Center of the U.S. Geological Survey (USGS) in Denver,
     Colorado. He received a B.A. in geology from San Jose State University, an M.S.
     in geology from San Diego State University, and a Ph.D. in geochemistry from
     Colorado School of Mines. He was a petroleum exploration geologist with Atlantic
     Richfield for eight years (1978 to 1986) in Colorado, California, and Texas,
     and has been with the USGS in Denver since 1987. His research focuses on the
     application of petroleum and source-rock geochemistry to identifying, characterizing,
     and mapping petroleum systems.\
