TL;DR: In this article, a time-series of Rock-Eval and thermal desorption-gas chromatography (TD-GC) analyses have been carried out on an organic-rich Devonian Duvernay Formation shale core sample from the Western Canada Sedimentary Basin (WCSB) and an organiclean Ordovician Lotbiniere Formation (Lotbiniere) core sample, which still contains high relative concentrations of C7-C9 hydrocarbons.

TL;DR: The biological marker compounds 17α(H) and 17β(H), 23,28-bisnorlupane have been identified in a coaly interval at about 3300-3320 m depth within the lower Taglu Sequence (early Eocene) in the Immiugak A-06 well in the Beaufort-Mackenzie Basin this article.

TL;DR: In this article, an integrated chemical and petrographic approach for distinguishing solid bitumens formed by thermal cracking and by thermochemical sulfate reduction (TSR) was presented, which suggests that sulfate supply appears to be a major limiting factor for the TSR reactions involving gaseous alkanes.

TL;DR: In this article, a well-documented case history in Western Canada sedimentary basin using two-dimensional gas chromatography has produced a useful tool for fingerprinting thermochemical sulfate reduction (TSR)-affected petroleum fluids.

TL;DR: In this paper, the degree of physicochemical transformation of dispersed organic matter (DOM) and zooclasts in BRF petroleum source rock after artificial maturation was quantitatively and quantitatively assessed, and the relationship between graptolite, chitinozoan, vitrinite-like particle and bitumen reflectance was determined with increasing pyrolysis temperature and the thermal maturity.
