| Résumé | (disponible en anglais seulement)
A technical meeting was held on October 6, 2015, at the downtown campus of the University of Calgary to discuss the effectiveness of the traffic light protocol
(TLP) approach for management of risks from induced seismicity. The meeting was attended by 64 participants from industry (55%), various government agencies (25%), academia (10%), and professional societies (5%). The role of TLP in the mitigation of
seismic hazards from induced seismicity and its challenges were examined. Three major issues with the current magnitude-based TLPs were identified: (1) possible confusion due to the magnitude uncertainty for an induced seismic event, (2) lack of a
link to the impact/consequences of reported seismic event(s), and (3) need to integrate other potential hazard indicators. To improve the effectiveness of existing TLPs, the following changes are recommended: (1) incorporate ground motion information
into TLPs such that decisions can be made based on better assessment of the actual risk, (2) develop a standardized approach for earthquake magnitude calculation, and (3) make the TLPs more adaptive to local hazard conditions through research and
incorporation (as appropriate) of other hazard indicators. A number of action items were brought forward at the workshop: (1) establishing a uniform standard for seismic data collection and assessment, (2) establishing a coherent framework of data
sharing for induced seismicity monitoring and research, (3) sharing other types of data, such as locations of known faults, and (4) taking more proactive approaches to establish best practices and to mitigate seismic risk from induced seismicity.
These actions will greatly strengthen the reputation of the hydrocarbon industry with respect to proactive, sensitive and responsible development of unconventional sources. If these steps can be implemented in a timely and effective manner, Canada
has the potential to be a world leader in monitoring, understanding and mitigating hazards and risks from injection-induced seismicity. |
| Résumé | (Résumé en langage clair et simple, non publié)
Une réunion technique a eu lieu le 6 Octobre 2015, sur le campus du centre-ville de l'Université de Calgary pour discuter de l'efficacité du
protocole type "feux de circulation" (TLP) pour la sismicité induite. La réunion avait un total de 64 participants de l'industrie (55%), de divers organismes gouvernementaux (25%), d'universités (10%), et de Lindustrie (5%). Le rôle du TLP dans
l'atténuation des risques sismiques de la sismicité induite et ses défis ont été examinés. Trois grandes lacunes des TLP actuels ont été identifiées. Pour améliorer efficacement les TLP actuels, il a été recommandé (1) d'incorporer des informations
de mouvement du sol aux TLP de telle sorte que les décisions soient prises en fonction de l'évaluation du risque réel, (2) de normaliser le calcul de la magnitude du tremblement de terre, et (3) rendre les TLP plus adaptés aux conditions locales des
risques. Un certain nombre de points d'action a également été soulevé pour définir la voie à suivre. |
