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.

加拿大的能源行业在国内外受到的威胁在国际和国际上受到了推动变化的可持续性和经济力量的威胁。该研究计划将为大幅度改进现有技术（例如液压压裂（HF）），并推动新的地热能量和碳固存运行提供工具。 高速脉冲注射到多孔和/或断裂的岩石中具有巨大的潜力；但是，将过程输入输入到流体岩石骨折系统的复杂波行为所需的现有仿真工具是完全不足的。现有的分析工具在（i）多孔培养基和（ii）裂缝中的流体流动中不适当地忽略了流体惯性和动量。此外，（iii）这些传统工具通常在计算上太昂贵（即时间），无法用于行业。 该计算能源进步研究计划将开发新型计算工程（CE）工具，以创新为加拿大能源领域的地质力学和断裂过程创新模拟技术。该程序的目标是发展：i）用于模拟多孔岩石中动态现象的创新数值方法； 2）适合非态和动态条件的新型断裂流和HF模型； 3）克服许多多物理学模拟模拟的计算可比性的高级技术。为了在模拟技术中取得这些必要的进步，必须实现所有这三个目标。该研究计划不仅会创建新的知识，理论和技术，还将为加拿大能源行业的未来提供计算工程和高素质人员（HQP）的地质力学的重要培训。该课程将支持6位博士学位和10名本科生。研究将在公平且包容的环境中进行，在该环境中，多样化的团队将通过在国际会议上的顶级期刊和演讲中发布HQP-Lead手稿来动员知识。 该计算能源进步研究计划的持续10年愿景是扩大多孔和自然破裂岩石中热 - 氢化机械过程所需的CE基础，以使发现创新，优化和运营加拿大能源项目所需的新的地质力学知识。该研究计划的目的是使加拿大能源行业在运营上更加有效，并且越来越可持续。
