Seismic acquisition system for induced earthquake monitoring and analysis

最近在阿尔伯塔的福克斯溪发生的地震引发了一场关于水力压裂（简称“压裂”）提高石油和天然气采收率的风险和环境影响的全球辩论。 在这个以前平静的地区发生的三次地震超过了4.0级的矩震级，这是世界上最大的压裂引起的事件之一。 注入作业于2015年6月暂停，以符合加拿大第一个轻质地下法规。 然而，在页岩气增产威尔斯井附近缺乏地震接收器极大地妨碍了地震的检测和定位，特别是对于地下断层、临界性和应力条件的评估至关重要的2-4级地震。

Recent earthquakes in Fox Creek, Alberta have sparked a global debate on the risks and environmental impacts of hydraulic fracturing (for short, 'fracking') for enhanced oil and gas recovery. Three earthquakes in this previously quiescent region exceeded a moment magnitude of 4.0, which rank among the largest fracking-induced events in the world. Injection operations were temporarily suspended in June 2015, in compliance with the first Traffic-light subsurface regulation in Canada. The lack of seismic receivers in the vicinity of shale gas stimulation wells, however, greatly hamper the detection and location of earthquakes, especially the magnitude 2-4 events that are crucial to the evaluation of subsurface fault(s), criticality and stress conditions.
