Analysis of the sulfur content and type using the Rock-Eval 7S method did not indicate elevated contents of total sulfur and total organic-linked sulfur in organic-rich rocks selected...

... Abstract Hydrogen Sulfide (H 2 S) is a hazardous gas commonly found during drilling and production of crude oil and gas. H 2 S can be naturally generated in reservoirs through microbial sulfate reduction (MSR), thermochemical sulfate reduction (TSR), and kerogen cracking. H 2 S can also...

.... A kinetics model was derived to model the co-generation of sulfur bearing species from kerogen with hydrocarbons and the subsequent evolution during secondary cracking, from which the total sulfur content in oil and the H 2 S content in gas at different maturities were predicted. Results Across...

... Abstract The wettability of organic-rich mudrocks has significant impacts on multiphase fluid flow and hydrocarbon recovery. Since kerogen can constitute a significant volumetric fraction of mudrocks, the wettability of kerogen can considerably affect the wettability of organic-rich mudrocks...

..., but also its relationship with pyrite and how these minerals can influence the chemistry of kerogen and ultimately its hydrocarbon generation. Introduction Pyrite's ability to chemically sequester the sulfide created from microbial activity can have profound effects on the kerogen chemistry (Hughes et...
