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.\

Chapter 3: Geologic Assessment of Undiscovered Oil and Gas Resources in the Phosphoria Total Petroleum System of the Wind River Basin Province, Wyoming Chapter 3: Geologic Assessment of Undiscovered Oil and Gas Resources in the Phosphoria Total Petroleum System of the Wind River Basin Province, Wyoming
The Phosphoria Total Petroleum System (TPS) encompasses the entire Wind River Basin Province, an area of 4.7 million acres in central Wyoming. The source rocks most likely are black, organic-rich shales of the Meade Peak and Retort Phosphatic Shale Members of the Permian Phosphoria Formation located in the Wyoming and Idaho thrust belt to the west and southwest of the province. Petroleum...

Upper cretaceous microbial petroleum systems in north-central Montana Upper cretaceous microbial petroleum systems in north-central Montana
Cenomanian to Campanian rocks of north-central Montana contain shallow economic accumulations of dry natural gas derived from microbial methanogenesis. The methanogens utilized carbon dioxide derived from organic matter in the marginal marine sediments and hydrogen from in situ pore water to generate methane. The most recent USGS assessment of the shallow gas resources of eastern Montana...

Executive Summary — Assessment of undiscovered oil and gas resources of the San Joaquin Basin Province of California, 2003 Executive Summary — Assessment of undiscovered oil and gas resources of the San Joaquin Basin Province of California, 2003
In 2003, the U.S. Geological Survey (USGS) completed an assessment of the oil and gas resource potential of the San Joaquin Basin Province of California (fig. 1.1). The assessment is based on the geologic elements of each Total Petroleum System defined in the province, including hydrocarbon source rocks (source-rock type and maturation and hydrocarbon generation and migration), reservoir...

Petroleum systems of the San Joaquin Basin Province, California -- geochemical characteristics of oil types: Chapter 9 in Petroleum systems and geologic assessment of oil and gas in the San Joaquin Basin Province, California Petroleum systems of the San Joaquin Basin Province, California -- geochemical characteristics of oil types: Chapter 9 in Petroleum systems and geologic assessment of oil and gas in the San Joaquin Basin Province, California
New analyses of 120 oil samples combined with 139 previously published oil analyses were used to characterize and map the distribution of oil types in the San Joaquin Basin, California. The results show that there are at least four oil types designated MM, ET, EK, and CM. Most of the oil from the basin has low to moderate sulfur content (less than 1 weight percent sulfur), although a few...

Source-rock thickness and organic richness are important input parameters required for numerical modeling of the geohistory of petroleum systems. Present-day depth and thickness maps for the upper Miocene Monterey Formation, Eocene Tumey formation of Atwill (1935), Eocene Kreyenhagen Formation, and Cretaceous-Paleocene Moreno Formation source rocks in the San Joaquin Basin were...
