"The Montney Formation is a highly productive hydrocarbon reservoir that is of great economic importance to Canada, however production is often dogged by the presence of hydrogen sulfide (H₂S), a highly toxic and corrosive gas. Mapping H₂S distribution across the Montney basin in the Western Canadian Sedimentary Basin (WCSB) is fundamental to understanding the processes responsible for its occurrence. We derive a Montney-specific dataset of well gas and water geochemistry from the publically available archives of the Alberta Energy Regulator (AER) and British Columbia Oil and Gas Commission (BCOGC) conducting quality assurance and control procedure before spatial interpolation. Empirical Bayesian Kriging is used to interpolate H₂S across the whole Montney basin resulting in maps of H₂S from hydrocarbon gas, condensates, and water; along with maps of sulfate and chloride ions in water. These interpolations illustrate the heterogeneous distribution of H₂S across the basin with the highest concentrations in the Grande Prairie area along with several other isolated regions. Maps of H₂S in gas, condensates, and water exhibit similar trends in H₂S concentrations, which with future research may help elucidate the origin of H₂S in the Montney"--Abstract, page 1.
