Microseismic events are very small earthquakes that can be associated with fracturing and fluid flow inreservoirs. These events are rarely, if ever, felt at the surface due to their low magnitudes. Microseismicity is used by the oil and gas industry to monitor hydraulic stimulation of "tight" hydrocarbon reservoirs. As such, it is one of the technologies underpinning the recent revival of conventional oil production in Western Canada, as well as the development of new tight-hydrocarbon fields. Increased hydrocarbon production generally also leads to increased water production, which must either be treated, recycled or disposed of underground. In some cases, hydraculic fracturing treatments and/or salt-water disposal has led to fault reactivation, causing seismicity felt at the surface. The current state of microseismic technology is ripe for accelerated discovery within an established university-industry partnership (Microseismic Industry Consortium). The objectives of this collaborative research and development program are: 1) to continue ongoing research on how to best process and interpret microseismic data; 2) to create new knowledge to improve our understanding of geomechanical aspects of earthquake processes; 3) to investigate if causal links exist between felt seismicity, hydraulic fracturing treatments and salt-water disposal, and if so how to reduce the hazard of induced seismicity; 4) to train highly-qualified personnel (HQP) to meet the demands of industry within this important technical field; and, 5) to enhance knowledge transfer between academia and industry. In particular, this project will provide support for at least 18 B.Sc. 4 M.Sc., 6 Ph.D. students, and 5 postdoctoral fellows.The university-industry synergies established through this partnership will create an innovation platform that promises to yield game-changing advances in the monitoring, modeling and interpretation of felt and non-felt induced (micro)-seismicity.

微丝膜事件是非常小的地震，可能与破裂和流体流动性相关。这些事件很少（如果有的话）由于其低幅度而在表面上感觉到。石油和天然气工业使用微吸毒性来监测“紧密”碳氢化合物的液压刺激。因此，它是加拿大西部传统石油生产以及新的紧密碳酸盐领域的发展的基础的技术之一。碳氢化合物产生的增加通常还会导致水生产增加，这要么必须进行地下处理，再生或处置。在某些情况下，水力压裂处理和/或盐水处置导致断层重新激活，从而导致表面的地震性。在建立的大学 - 行业伙伴关系（微震震行业财团）内，微观震荡技术的当前状态已成熟。该协作研究与开发计划的目标是：1）继续研究如何进行最佳处理和解释微震源数据； 2）创建新知识，以提高我们对地震过程的地质力学方面的理解； 3）调查感受的地震性，水力压裂处理和盐水处置之间是否存在因果关系，如果是这样，如何减少诱发地震性的危害； 4）培训高度合格的人员（HQP），以满足这一重要技术领域的行业需求； 5）增强学术界与工业之间的知识转移。特别是，该项目将为至少18 B.Sc提供支持。 4 M.Sc.，6博士学位学生和5个博士后研究员。通过这种合作伙伴关系建立的大学 - 行业协同作用将创建一个创新平台，有望在监视，模型和非毛毡和非诱发（微型）（Micro）的观察性的监视，建模和解释中产生改变游戏规则的进步。
