Paul Lillis
Scientist Emeritus with the Central Energy Resources Science Center
Paul Lillis is a recently retired petroleum geochemist with 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.\

Characterization of Northern California petroleum by stable carbon isotopes Characterization of Northern California petroleum by stable carbon isotopes
The purpose of this study is to characterize natural occurrences of petroleum at the surface and in the subsurface within northern California in order to define and map petroleum systems for U.S. Geological Survey energy resource assessments. Furthermore, the chemical characterization and mapping of natural petroleum occurrences could also be used to discriminate natural occurrences from

Open File Report 01-480 was designed as a large format poster for the Annual Meeting of the American Association of Petroleum Geologists and the Society for Sedimentary Geology in Denver Colorado in June 2001. It is reproduced here in digital format to make widely available some unique images of mudstones. The images include description, interpretation, and Rock-Eval data that resulted...

Organic geochemistry of oils from Oil Spring and Florence oil field near Canon City, Colorado Organic geochemistry of oils from Oil Spring and Florence oil field near Canon City, Colorado
Oil Spring is an oil seep located approximately 6 miles north of Ca?on City, Colorado. The purpose of this study is to determine whether the oil from Oil Spring and the oil from nearby Florence oil field share a common source. Bulk and molecular geochemical analyses show that the oil seep is most likely derived from a group of geochemically similar Cretaceous source rocks including the...

Geochemistry of oils from the Junggar basin, northwest China Geochemistry of oils from the Junggar basin, northwest China
The Junggar basin of northwestern China is a structural basin containing a thick sequence of Paleozoic-Pleistocene rocks with estimated oil reserves of as much as 5 billion bbl. Analyses of 19 oil samples from nine producing fields and two oil-stained cores in the Junggar basin revealed the presence of at least five genetic oil types. The geochemistry of the oils indicates source organic...

Soda Lake-Painted Rock(!) Petroleum System in the Cuyama Basin, California, U.S.A. Soda Lake-Painted Rock(!) Petroleum System in the Cuyama Basin, California, U.S.A.
The Cuyama basin, located in the central California Coast Ranges, was formed by extension during early Miocene time and was filled with a variety of nonmarine, marginal marine, and neritic to bathyal marine sediments. Low sulfur oil is produced primarily from the lower Miocene Painted Rock Sandstone Member of the Vaqueros Formation along a structural trend parallel to the Russell fault...
