A collaborative research and development project is proposed between BitCan Geosciences & Engineering Inc. (BitCan) and Dr. Gracie of the University of Waterloo (UW). The goal of the project is to take the first meaningful steps towards the development of a commercial simulator for Steam-Assisted Gravity Drainage (SAGD) suitable for use in the fast-paced iterative environment of engineering design. BitCan is the developer an advance Simulation Systems capable of capturing multi-physic phenomena including fluid flow, deformations, and heat transfer under both transient and dynamic conditions. However, the utility of these simulations, specifically in fast-pace and iterative engineering design environments, is greatly hampered by the Tyranny of Scales (ToS) - the difficulty of achieving computationally tractable simulations of complex processes like SAGD that inherently span multiple length and time scales. The ToS has not yet been overcome with High Performance Computing (HPC). A 3-year project to develop Reduce of Models (ROM) for multi-physics problems in geosciences and engineering is proposed, as a paradigm shifting and disruptive technology with the potential of addressing the ToS. ROMs are surrogate models which are highly efficient and derived from more complex and computationally expensive model using a range of Model Order Reduction (MOR) techniques. This project will evaluate existing MOR techniques for simulations of geomechanical phenomena and develop new MOR techniques for multi-physics problems. These objectives will be achieved in an equitable and diverse environment, supporting an inclusive team and superior outcomes. There's a large environmental, economic, and social impetus to see a significant reduction in the GHG emissions and water use associated with SAGD and Oil Sands development in Canada. Simulations can provide important insights and new knowledge into subsurface processes during SAGD leading to process innovations; however, the cost of such models is often prohibitive. Should the ToS be overcome, the environmental impact can be reduced and the competitiveness of Canada's industry can be increased.

在BitCan Geosciences＆Engineering Inc.（BitCan）和滑铁卢大学（UW）的Gracie博士（UW）之间提出了一个合作研究与开发项目。该项目的目的是采取第一个有意义的步骤，开发用于蒸汽辅助重力排水（SAGD）的商业模拟器，适合于工程设计的快节奏迭代环境。 BITCAN是开发人员的预先模拟系统，能够捕获瞬态和动态条件下的流体流，变形和传热，包括流体流，变形和传热。但是，这些仿真的实用性，特别是在快速和迭代工程设计环境中的实用性，受到量表的暴政（TOS）的极大阻碍，这是实现固有长度和时间尺度的SAGD（如SAGD）进行计算可触及的复杂过程的难度。高性能计算（HPC）尚未克服TOS。提出了一个为期三年的项目（ROM），以解决地球科学和工程中多物理问题的模型（ROM），作为一种范式转移和破坏性技术，具有解决TOS的潜力。 ROM是替代模型，使用一系列模型订购（MOR）技术源于更复杂且昂贵的模型。该项目将评估现有的MOR技术，以模拟地质力学现象，并为多物理问题开发新的MOR技术。这些目标将在公平和多样化的环境中实现，支持包容性团队和卓越成果。有一个巨大的环境，经济和社会动力，可以看到与加拿大的SAGD和油条开发相关的温室气体排放和用水量大大减少。模拟可以在下垂过程中提供重要的见解和对地下过程的新知识，从而导致过程创新；但是，这种模型的成本通常是过于望而却步的。如果克服TO，可以减少环境影响，并可以提高加拿大行业的竞争力。
