A majority of Canada's 1.5 million water wells4 and +200,000 producing oil and gas wells would benefit from in increase in production rate. Stimulation is used to improve fluid flow in under-performing reservoirs. Wavefront Technology Solutions (WFT) created the unique stimulation technology WaveAxe, which is used in the energy sector to increase production of hydrocarbons and in the environmental sector for remediation. Whereas standard stimulations are slow and steady, WaveAxe generates dynamic pressure pulses which mobilize inertia forces in both the fluid and in the rock causing pores to expand and the rock mass to fragment - resulting in superior permeability and production. However, successful application of WaveAxe requires careful tuning of process variables to achieve synchronization of the complex waves generated in both the fluid and the rock mass; otherwise, the treatment may fail. To meet the needs of its domestic and international clients, WTS, desires to develop a framework to quickly determine optimal process parameters that maximize treatment effectiveness. The project is divided into four key objectives: (1) Development WaveAxe model and integration into hydraulic fracture simulator, (2) dimensionless analysis, (3) parameter study, and (4) development of design charts. This research will provide a more complete understanding of the complex multiphysics of the reservoir response to dynamic stimulation and enable the rapid design of treatments for a wider range of field conditions. These results are important for WTS and for the decision-making process of companies interested in using this technology in Canada and internationally. To increase creativity and innovation in this research project, consideration of equity, diversity, and inclusion (EDI) are core principles for the research team. The project will fund one Post-doctoral fellow who will receive training in computational mechanics and industry practises. In addition, they will be supported by mentoring programs offered through Women in Engineering and the Glow Centre.

加拿大150万口水井4和20多万口生产油气的威尔斯井中的大多数将受益于产量的增加。增产措施用于改善表现不佳储层中的流体流动。Wavefront Technology Solutions（WFT）创造了独特的增产技术WaveAxe，该技术用于能源部门以增加碳氢化合物的产量，并用于环境部门以进行修复。标准增产措施缓慢而稳定，而WaveAxe产生动态压力脉冲，调动流体和岩石中的惯性力，导致孔隙膨胀和岩体破碎，从而实现上级渗透率和产量。然而，WaveAxe的成功应用需要仔细调整过程变量，以实现流体和岩体中产生的复杂波的同步;否则，治疗可能会失败。 为了满足国内和国际客户的需求，WTS希望开发一个框架，以快速确定最佳工艺参数，最大限度地提高处理效果。该项目分为四个主要目标：（1）开发WaveAxe模型并集成到水力压裂模拟器中，（2）无量纲分析，（3）参数研究，以及（4）开发设计图表。这项研究将提供一个更完整的了解复杂的多物理的储层响应动态刺激，并使更广泛的现场条件下的治疗的快速设计。这些结果对于WTS以及有兴趣在加拿大和国际上使用该技术的公司的决策过程非常重要。 为了提高本研究项目的创造力和创新性，考虑公平，多样性和包容性（EDI）是研究团队的核心原则。该项目将资助一名博士后研究员，他将接受计算力学和工业实验室的培训。此外，他们将通过妇女在工程和辉光中心提供的辅导方案的支持。
