Passive Seismic Monitoring of CO2 Storage at Weyburn
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010Co-Authors: James P Verdon, J.-michael Kendall, Quentin J. Fisher, Don White, Doug Angus, Theodore I. UrbancicAbstract:Passive Seismic Monitoring has been ongoing at the IEA GHG Weyburn-Midale Project since 2003. We present the microSeismic activity recorded during a 5 year period, showing event timings and locations, and discussing the implications for storage integrity. We link passive Seismic observations with predictions about event locations and Seismic anisotropy made by a simple geomechanical model, demonstrating the importance of combining observation with modelling in order to guarantee successful storage.

Passive Seismic Monitoring of carbon dioxide storage at Weyburn
The Leading Edge, 2010Co-Authors: James P Verdon, Don J. White, Doug A. Angus, J.-michael Kendall, Quentin J. Fisher, Theodore I. UrbancicAbstract:Passive Seismic Monitoring of carbon dioxide storage at Weyburn-Midale Field is in the Williston Basin of southern Saskatchewan, Canada has been reported. Passive Seismic Monitoring provides a different kind of information to controlled-source techniques. Controlled-source 4D Seismic Monitoring has been largely successful in imaging the plumes of CO2 migrating away from the injection wells, with negative time-lapse amplitude differences marking zones of CO2 saturation. Passive Monitoring at Weyburn has focused on a single pattern within the field. The distribution of injection- related event locations also appears to correlate with the regions of CO2 saturation that have been identified using 4D Seismic. Geomechanical modeling shows that the evolution of stress during injection is likely to preferentially open the set, making it dominate the splitting results. Simple geomechanical modeling reveals that areas around and above production wells will be at greater risk of failure than around the injection well.

Recent advances in Seismic Monitoring technology at Canadian mines
Journal of Applied Geophysics, 2000Co-Authors: Theodore I. Urbancic, Cezar Ioan TrifuAbstract:We provide an overview of the current status of Seismic Monitoring instrumentation employed in Canadian underground mines. Based on several case studies, we outline how passive Seismic Monitoring techniques are being used to evaluate fractures and stress conditions associated with ore extraction at depth. It is shown that induced microSeismicity allows for the remote Monitoring of active fractures, delineating modes of failure with advancing excavation fronts, and identifying variations in principal stress orientations during sequential stages of mining. Advances into the characterization of excavation zone of influence through deformation state analysis and the use of Seismic hazard analysis to evaluate the potential for ground instability are also discussed.

Seismic Monitoring System of Marmaray Submerged Tube Tunnel
Journal of Earthquake and Tsunami, 2016Co-Authors: S. Umit Dikmen, Erdal Safak, Ali Pinar, Ayse Edincliler, Mustafa ErdikAbstract:Monitoring the behavior of the structures is essential to identify changes in behavior and/or response of structures. It is also important that certain critical systems are safely shutdown during a potentially destructive earthquake. The objective of this study is to present the Seismic Monitoring and early warning systems set in the recently commissioned Marmaray Submerged Tunnel and report on the observations made during the May 24, 2014 Northern Aegean Earthquake (Mw = 6.9).

Seismic Monitoring in underground mines: A case of mufulira mine in Zambia: Using wireless sensor networks for Seismic Monitoring
2010 International Conference on Electronics and Information Engineering, 2010Co-Authors: Nchimunya Chaamwe, Hongbo JiangAbstract:Sudden earth tremors (Seismic events) and the accompanying ground falls constitute a major threat to underground mining operations in most underground mines in Zambia. Seismic Monitoring is therefore an important exercise that ensures not only a safe working environment for workers but ensures the safety of communities living nearby the mines. This paper discusses Seismic events Monitoring at one of the biggest mines in Zambia called Mufulira Copper mine. A study on Seismic Monitoring was carried out at the mine through observations, interviews and record inspections. The study revealed the different methods used over a period of time and it also revealed some major causes of Seismicity at the mine. The paper then proposes the use of Wireless Underground Sensor Networks (WUSNs) to monitor Seismic events in underground mines. Wireless sensor networks uses sensors that are capable of not only sensing, but processing and transmitting data, hence reducing on the wiring that is characterized by the current-system.
