Unconventional shale reservoirs in Western Canada, host the majority of Canada's known natural gas resources as well as significant volumes of hydrocarbon liquids. These reservoirs include no to variable, and poorly predictable amounts of hydrogen sulphide and hydrocarbon liquids. In order to predict the distribution, abundance and anticipate production rates of hydrogen sulphide and producible fluids from unconventional reservoirs, a multi-faceted, three year study is proposed that is designed to meet both short and longer term exploration and development needs of industry, environmental management, and resource stewardship. The study will further identify optimum methods for well site and mid-stream treatment of low concentration hydrogen sulphide gas and identify optimum biocides or other treatments to inhibit in situ formation of sour gas. The results of the study will assist the Crown in providing stewardship of the resources and for evaluating and mitigating the environmental impact of sour gas and liquids development. The study will provide factual data to stake holders on risks and hazards.The deliverables of the study will be detailed mapping of produced gases including hydrogen sulphide, and liquids. The predictive maps would be based on fields studies, geochemical modeling and laboratory tests that will include analyses of the selective diffusion, solution, and adsorption of hydrogen sulphide in the presence of other fluids. The data and models will provide both industry and regulators critical information for the design of exploration and development programs including environmental management of hazardous gases.

加拿大西部的非常规页岩储层蕴藏着加拿大大部分已知的天然气资源以及大量的碳氢化合物液体。 这些储层中含有的硫化氢和碳氢化合物液体的量不可变且难以预测。 为了预测非常规油​​藏中硫化氢和可采流体的分布、丰度并预测产量，提出了一项为期三年的多方面研究，旨在满足工业、环境的短期和长期勘探和开发需求。管理和资源管理。 该研究将进一步确定低浓度硫化氢气体的井场和中游处理的最佳方法，并确定抑制酸性气体原位形成的最佳杀菌剂或其他处理方法。研究结果将协助政府提供资源管理以及评估和减轻酸性气体和液体开发对环境的影响。该研究将为利益相关者提供有关风险和危害的事实数据。该研究的成果将是所产生的气体（包括硫化氢）和液体的详细绘图。 预测图将基于现场研究、地球化学建模和实验室测试，其中包括对其他流体存在下硫化氢的选择性扩散、溶解和吸附的分析。这些数据和模型将为行业和监管机构提供设计勘探和开发计划（包括有害气体环境管理）的关键信息。
