Computing Energy Advancement: Computational Engineering for Geomechanics and Fracture

加拿大的能源工业在国内和国际上都受到可持续性和经济力量的威胁，这些力量正在推动变革。该研究项目将为大幅改进水力压裂（HF）等现有技术提供工具，并推动新的地热能和碳封存技术的发展。高速率脉冲注入多孔和/或裂缝岩石具有巨大的潜力；然而，现有的模拟工具需要将过程输入调整为流体-岩石-破裂系统的复杂波动行为，这是完全不够的。现有的分析工具不恰当地忽略了(1)多孔介质中的流体惯性和动量，(2)裂缝中的流体流动。此外，（iii）这些传统工具通常在计算上（即时间上）过于昂贵，无法在工业中实际使用。该计算能源进步研究项目将开发新的计算工程（CE）工具，为加拿大能源部门的地质力学和裂缝过程创新模拟技术。本计划的目标是发展：1)模拟多孔岩石动态现象的创新数值方法；2)适用于非稳态和动态条件的新型断裂流动和高频模型；3)先进的技术来克服许多多物理场地质力学模拟的计算困难。为了使仿真技术取得这些必要的进步，必须实现这三个目标。该研究项目不仅将创造新的知识、理论和技术，还将为未来加拿大能源行业的高素质人才（HQP）提供重要的计算工程和地质力学培训。本项目将资助6名博士生和10名本科生。研究将在公平和包容的环境中进行，在这种环境中，多元化的团队将通过在顶级期刊上发表hqp主导的手稿和在国际会议上发表报告来调动知识。“计算能源进步”研究计划的10年愿景是，扩展模拟多孔岩石和自然破裂岩石中热-水-机械过程所需的CE基础，从而发现创新、优化和运营加拿大能源项目所需的新地质力学知识。这项研究计划的目的是使加拿大的能源工业运作更有效率，越来越更具可持续性。

Canada's energy industry is under threat both domestically and internationally from sustainability and economic force which are propelling change. This research program will provide the tools to dramatically improve existing technologies like Hydraulic Fracturing (HF) and to advance new Geothermal Energy and Carbon Sequestration operations. High rate pulsing injection into porous and/or fractured rock offers great potential; however, the existing simulation tools needed to tune process inputs to the complex wave behavior of the fluid-rock-fracture system are completely inadequate. Existing analyses tools inappropriately neglect fluid inertia and momentum in (i) porous media and (ii) fluid flow in fractures. Furthermore, (iii) these traditional tools are often too expensive computationally (i.e., time) for practical use in industry. This Computing Energy Advancement research program will develop novel computational engineering (CE) tools to innovate simulation technology for geomechanics and fracture processes for Canada's energy sector. The objectives of this program are to develop: I) innovative numerical methods for the simulating dynamic phenomena in porous rock; 2) novel fracture flow and HF models suitable for non-steady and dynamics conditions; 3) advanced techniques to overcome the computational intractability of many multiphysics geomechanic simulations. To make these necessary advancements in simulation technology, all three of these objectives must be realized. Not only will this research program create new knowledge, theory, and technology, it will also provide vital training in computational engineering and geomechanics of highly qualified personnel (HQP) for the future of Canada's energy industry. This program will support 6 PhD and 10 undergraduate students. Research will be conducted in an equitable and inclusive environment in which the diverse team will mobilize knowledge through the publication of HQP-lead manuscripts in top-tier journals and presentations at international conferences. The on-going 10 year vision of this Computing Energy Advancement research program is to expand the foundations of CE needed to simulation of thermo-hydro-mechanical processes in both porous and naturally fractured rock to enable discovery the new geomechanics knowledge needed to innovate, optimize, and operate Canadian energy projects. The aims of this research program are to make Canada's energy industry operationally more efficient and increasingly more sustainable.
