The pre-Devonian shales are important natural archives, preserving extensive information
on paleobiology, paleoenvironment, and paleoecology, and also acting as important …

The ratio of dibenzothiophene to phenanthrene and the ratio of pristane to phytane, when
coupled together, provide a novel and convenient way to infer crude oil source rock …

The fluorescence spectra of crude oils, synthesized as hydrocarbon fluid inclusions (hcfi) in
NaCI crystals, have been recorded and correlated with crude oil chemical analysis. The …

Abstract The Bakken Formation of the Williston Basin is a prime example of an
unconventionally produced petroleum system, with a low-permeability reservoir that requires …

Abstract The Late Devonian and Early Mississippian Bakken and Exshaw formations are a
continuum of regionally correlated, organic-rich (up to 35% total organic carbon), black …

The petroleum system concept was first applied in 1974 (Dow/Williams) to identify three oil
systems in the Williston Basin, and recent studies have expanded the number to at least …

The Upper Devonian Nisku Formation reservoirs of the Brazeau river area of west-central
Alberta, Canada, produce oil and sweet and sour gas condensate. Generally, oil pools are …

Source-and age-related biomarker and isotopic data were measured for more than 1000
crude oil samples from wells and seeps collected above approximately 55 deg N latitude. A …

Abstract The Bakken Formation is a major unconventional shale play in North America,
which lacks an independent calibration for accurately correlate thermal maturity from …

Low δ18O values of formation waters, collapse structures related to salt dissolution,
hydrodynamic blowout structures, and biodegradation of oils all suggest a significant influx …
