Monitoring seismicity and crustal structure of the Canoe Reach geothermal field

Canoe Reach地热田的开发将提供一个理想的发电资源，可以为周围地区和其他地区的社区提供电力。作为Canoe Reach能源项目的一部分，为了实现这一目标，Borealis GeoPower正在进行一系列研究，以更好地了解地热场的结构及其与邻近断层的关系。为了这个项目，Borealis计划在Canoe河段附近钻一口勘探井，以更好地评估温泉区域的热条件和浅层地壳结构。申请人将利用NSERC Engage基金与borealis GeoPower合作，开展一项新的地震调查，以确定地热田开发初期当地断层对钻井和流体注入的反应方式。该项目为期6个月，时间跨度从钻探前到注入后，这将突显该地区在地热开发的初始阶段是如何被改造的。作为该项目的一部分，我们将获得一个新的地震数据集，我们将监测Canoe Reach地热田，绘制地震地图并描述断层特征。我们的观测将以以前无法获得的细节揭示该地区地震活动和断层分布的细节。识别地震活动或断层的变化将为Borealis提供数据，以监测它们的活动如何改变该地区。该项目将为研究生提供支持：(1)探测当地地震活动，(2)表征与这些地震相关的断层方向，(3)检查地震波的到达并评估它们的传播是否受到各向异性地震速度的影响，以及(4)测量这些观测结果是否表现出时间变化，以及这些变化与地热开发过程中发生的活动时间的关系。整合这些结果将为Borealis提供对区域地震活动和断层的深入了解，从而使Canoe Reach能源项目能够得到最佳开发。

The development of the Canoe Reach geothermal field will provide an ideal resource for generating power thatcan be delivered to communities in the surrounding area and beyond. To achieve this goal, which is part oftheir Canoe Reach Energy project, Borealis GeoPower is conducting a series of studies to better understand thestructure of the geothermal field and its relation to the neighboring faults. For this project Borealis plans to drillan exploration well near Canoe Reach to better assess the thermal conditions and the structure of the shallowcrust in the area of the hot springs. Utilizing NSERC Engage funding, the applicant will collaborate withBorealis GeoPower by conducting a novel seismic investigation to identify the manner in which local faultsrespond to drilling and fluid injection during the initial development of a geothermal field. The six-monthduration of this project is timed to span from prior to drilling to post-injection, which will highlight how theregion has been modified during the initial stages of geothermal development. Using a new seismic dataset thatwill be acquired as part of this project, we will monitor the Canoe Reach geothermal field to map its seismicityand characterize its faults. Our observations will reveal details about the distribution of seismicity and faultswithin the region at previously unattainable detail. Identifying changes in seismicity or faults will provide datato Borealis to monitoring how their activities modify the region.This Engage grant will provide support for graduate students to: (1) detect local seismicity, (2) characterize theorientation of faulting associated with these earthquakes, (3) examine arrivals of seismic waves and assess iftheir propagation appears to have been affected by anisotropic seismic velocities, and (4) measure whetherthese observations exhibit temporal variations and how those relate to the timing of activities taking placeduring geothermal development. Integrating these results will provide Borealis with insights into the regionalseismicity and faults so that the Canoe Reach Energy project can be optimally developed.
