Distribution, origin and implications of producible liquids and hydrogen sulphide in Canadian unconventional reservoirs with insights into lateral and stratigraphic variability

加拿大西部的非常规页岩储层拥有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。 这些储层不含硫化氢和烃类液体，甚至含量不定，且难以预测。 为了预测硫化氢和非常规油气藏可采流体的分布、丰度和预期产率，提出了一项多方面的三年期研究，旨在满足短期和长期勘探和工业、环境管理和资源管理的开发需求。 这项研究将进一步确定井场和中游处理低浓度硫化氢气体的最佳方法，并确定最佳的杀菌剂或其他处理方法，以抑制原地形成酸性气体。研究结果将有助于皇家提供资源管理，并评估和减轻酸性气体和液体开发对环境的影响。这项研究将向利益攸关方提供有关风险和危害的事实数据。 该研究的成果将是包括硫化氢在内的生产气体和液体的详细绘图。 预测图将以实地研究、地球化学建模和实验室测试为基础，其中将包括对硫化氢在其他流体存在下的选择性扩散、溶解和吸附的分析。这些数据和模型将为行业和监管机构设计勘探和开发计划提供关键信息，包括危险气体的环境管理。

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.
