Unconventional Shale Gas Development (SGD) has the potential to contribute trillions of dollars to Canada's GDP over the next 30 years; however, significant questions remain about the environmental and public health risks associated with Hydraulic Fracturing (HF)-the enabling technology of SGD. The "Hydraulic Fracture Simulation and Risk" (HF-SR) research and training program will a) develop new knowledge about the mechanics of HF and b) establish the foundations for a comprehensive Risk Assessment and Risk Management (RA/RM) framework for Canada. Together these goals will inform public policy, enable effective risk assessment, and lead to innovative HF practices, which are more economically and environmentally sustainable.******The proposed Discovery Grant "Hydraulic Fracture Simulation for Shale Gas Development" will develop computational mechanics knowledge to increase the computationally efficiency of eXtended Finite Element Method (XFEM) HF simulators based by several orders of magnitude. This will be achieved through four milestones: 1) higher-order XFEM approximations; 2) novel Operator Splitting methods; 3) local-global XFEM tip enrichments; and 4) Reduce Order Models. The simulation technology developed through these milestones will be mobilized, in part, through the industry collaborator of a NSERC Strategic grant and other industry partnerships. Knowledge will be mobilized for academics through publications, conferences, and stakeholder workshops. The achievement of these milestones will lead to a suite of simulation technologies that are both sufficiently realistic and fast enough to be used in engineering design and risk assessment.******The Discovery Grant will train 24 Highly Qualified Personnel (HQP)-3 Doctoral, 1 Masters, 5 undergraduate cooperative education, and 15 undergraduate research assistant students-each HQP will be an integral member of a multi-disciplinary and multi-institutional research and training program. This is a key transformative feature of the HF-SR program. Since HF activities will substantially increase worldwide over the next five years, non-profit organizations, regulators, and industry will need a qualified workforce with expertise from the social sciences and engineering. Furthermore, extensive shale gas resources exist worldwide and are not yet being developed and so Canada will be strategically aligned to leverage HF research and knowledge in developing foreign markets. Over the next five years, this program will inject, at a critical time in SGD, technology, knowledge, and experts needed to realize the economic potential of SGD, while ensuring environmental sustainability and public health.********

在未来30年内，非常规页岩气开发（SGD）有可能向加拿大的GDP捐款数万亿美元；但是，关于与液压压裂（HF）的环境和公共卫生风险（SGD的促成技术）有关的重要问题。 “液压断裂模拟和风险”（HF-SR）研究和培训计划将a）开发有关HF和b的新知识。 这些目标共同为公共政策提供了信息，实现有效的风险评估并导致创新的HF实践，在经济上和环境上更可持续。****** ******拟议的发现赠款“针对页岩气体开发的水力裂缝模拟”将开发计算机械知识，以提高基于元素的扩展有限元元素方法（XFEM）基于元素的扩展有限元元素方法的计算效率。 这将通过四个里程碑来实现：1）高阶XFEM近似值； 2）新型操作员分裂方法； 3）局部全球XFEM尖端富集； 4）减少订单模型。 通过这些里程碑开发的模拟技术将通过NSERC战略赠款和其他行业合作伙伴关系的行业合作者动员。知识将通过出版物，会议和利益相关者讲习班动员学者。这些里程碑的实现将导致一系列模拟技术，这些技术既足够现实又足够快，可以在工程设计和风险评估中使用。****** ******探索赠款将培训24名高度合格的人员（HQP）-3博士学位，1名大师，1名大师，5个不足的研究助理教育和15个不足的研究助理成员，是一个杂货生的成员，是一体的杂物 - each-each-each-each-each-each-each the Eake-HQP HQP HQP，多机构研究与培训计划。这是HF-SR程序的关键变革功能。 由于HF活动将在未来五年内大幅增加，因此非营利组织，监管机构和行业将需要合格的劳动力，并具有社会科学和工程学的专业知识。此外，全球存在广泛的页岩气资源，尚未开发，因此加拿大将在战略上保持一致，以利用发展国外市场的HF研究和知识。 在接下来的五年中，该计划将在SGD，技术，知识和专家的关键时期内注射，以实现SGD的经济潜力，同时确保环境可持续性和公共卫生。**********
