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.

加拿大的能源工业在国内和国际上都面临着可持续发展和推动变革的经济力量的威胁。该研究计划将提供工具来显着改进水力压裂（HF）等现有技术，并推进新的地热能和碳封存作业。 向多孔和/或裂隙岩石中进行高速脉冲注入具有巨大的潜力；然而，调整过程输入以适应流体-岩石-断裂系统的复杂波动行为所需的现有模拟工具完全不够。现有的分析工具不适当地忽略了（i）多孔介质和（ii）裂缝中的流体流动中的流体惯性和动量。此外，（iii）这些传统工具在计算（即时间）上通常过于昂贵，无法在工业中实际使用。 该计算能源进步研究计划将开发新型计算工程（CE）工具，以创新加拿大能源部门的地质力学和断裂过程模拟技术。该计划的目标是开发： I) 用于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裂缝流和HF模型； 3）先进技术克服了许多多物理场地质力学模拟的计算困难性。为了在仿真技术方面取得这些必要的进步，所有这三个目标都必须实现。该研究项目不仅将创造新的知识、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地质力学方面高素质人才 (HQP) 的重要培训。该项目将支持 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，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的演讲来调动知识。 该计算能源进步研究计划的持续 10 年愿景是扩大模拟多孔和自然裂隙岩石中的热-水-机械过程所需的 CE 基础，从而能够发现创新、优化所需的新地质力学知识，并经营加拿大能源项目。该研究计划的目的是使加拿大能源行业的运营更加高效且更加可持续。
