Abstract Upper Permian Zechstein carbonate Ca2 gas reservoirs in the southern part of the
Pompeckj Block in the North German Basin locally contain up to 36 vol% hydrogen sulfide …

Natural gas in the Permian-Triassic Khuff Formation of Abu Dhabi contains variable amounts
of H 2 S. Gas souring occurred through thermochemical sulfate reduction of anhydrite by …

The stable carbon isotopic ratios (δ13C) of methane (CH4) and carbon dioxide (CO2) of gas-
rich fluid inclusions hosted in fracture-fill mineralization from the southern part of the Lower …

The accumulation of high H 2 S concentrations in oil and gas fields is usually associated
with deeply buried high-temperature carbonate reservoirs and is attributed to the abiological …

Sulfate rocks and organic sulfur from sedimentary organic matter are conventionally
assumed as the original sulfur sources for hydrogen sulfide (H2S) in oil and gas reservoirs …

The mechanism of thermochemical sulfate reduction (TSR) was investigated by separately
heating nC 24 with three different sulfates (CaSO 4, Na 2 SO 4, MgSO 4) in sealed gold …

Improved understanding of the reservoir mineral effects on the occurrence of
thermochemical sulfate reduction (TSR) and possible mechanisms is critical for petroleum …

Fluid inclusion gases in minerals from shale hosted fracture-fill mineralization have been
analyzed for stable carbon isotopic ratios of CH 4 using a crushing device interfaced to an …

Permian carbonate reservoir rocks (Stassfurt-Carbonate) of the CO2-province (Lower
Saxony Basin, NW Germany) are locally characterised by high amounts of CO2 leading to …

Fluid inclusions hosted in different stages of TSR-derived diagenetic minerals are expected
to record compositions and isotopes of paleo-fluids at the time of trapping during different …
