AbstractThe Montney resource play has evolved from a peripheral conventional play to one of the most important hydrocarbon-producing unconventional resource plays in North America and has remained resilient throughout the economic challenges of recent years. Despite maturing as a resource play as a result of more than 15 years of unconventional development and research there are still aspects of the play that are not fully de-risked and prediction of fluid quality remains haphazard due to the complex interplay of geological and engineering factors. Among these are the delineation of structural and stratigraphic barriers and conduits, identification of enigmatic source rocks, which defy traditional methods, evaluating effects of fluid migration and the difficulty in predicting phase behavior in a tight, but open system. This study uses a combined approach leveraging geochemical tools combined with spatial and stratigraphic analysis in an attempt to improve current understanding of these issues.
Summary(Plain Language Summary, not published)
The origin and distribution of hydrogen sulfide (H2S) - a highly toxic and corrosive gas in conventional and unconventional resources of the Western Canada Sedimentary Basin - was the subject of many studies. The Early Triassic Montney Formation, one of the major North American unconventional gas resources, contains a significant amount of H2S in some areas. Several research teams in western Canada including the Geological Survey of Canada, the University of Calgary, and the University of British Columbia are investigating this complex issue. This workshop will provide a venue to discuss the latest scientific advancements on this topic in order to reach a better understanding of the distribution, origin, and mitigation strategies to overcome the associated economic and environmental issues. This open file report presents the proceedings of the online workshop 'Hydrogen sulfide (H2S) in the Montney Formation - investigating a complex issue' on February 9th, 2022 in Calgary Alberta, organized by the Canadian Society for Unconventional Resources (CSUR), Natural Resources Canada (NRCan), and University of Calgary.
