Compound-specific S isotope anal. (CSSIA) of volatile organic sulfur compounds (VOSC) in petroleum gases was applied for the first time to two natural gas samples from the Triassic section of the Alberta Basin in Canada. For comparison, CSSIA was conducted for five condensate samples from adjacent wells. The anal. of VOSC in the gas samples revealed similarity in the sulfur isotope composition for thiols, sulfides, and H2S suggesting an isotopic equilibrium during the reaction between H2S and hydrocarbons in the reservoir. In contrast, one of the gas samples contained alkyl thiophenes with distinct δ34S values that suggest a different source, probably from oil or bitumen. The mol. and isotopic anal. of condensates revealed several phases of thiol interaction with H2S bearing similar δ34S value as the H2S in Gas A and B. Thermally stable OSC such as alkyl-, benzo- and dibenzo- thiophenes of all condensate samples kept their previous δ34S values and not the ones expected in isotopic equilibrium, indicating a recent migration of H2S to the reservoirs. The δ34S value of the H2S reacting with the gas and condensate samples is isotopically similar to H2S which could have generated during complete microbial or thermochem. sulfate reduction of the Charlie Lake anhydrite in the Triassic section, therefore making this process the likely source of the H2S. This study demonstrates the potential of sulfur isotope anal. of VOSC to interpret origin, migration pathways and provide a relative time frame for in-reservoir processes impacting present day natural gas properties. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Synthetic Route of C6H8S).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It is also used in the manufacturing of dyes such as thioindigo.Synthetic Route of C6H8S
