Abstract: Ranking Operation Scenarios for Effective Mitigation of Hydraulic Fracture-Induced Seismicity
As a preview to our April 2018 RECORDER featuring the focus topic: Induced Seismicity, we present the following abstract for one of the featured articles.
A magnitude-based, traffic light protocol is the most common mitigation approach to injection-induced seismicity, adopted by both regulators and operators throughout North America (Table 1). Despite challenges associated with a protocol based on an estimate of seismic source strength, magnitude-based protocols still prevail over alternatives such as using measured ground motions. Regardless of the attribute adopted to trigger alert levels, the resultant question becomes what operational change should be made to best mitigate seismic hazard. In this paper, a workflow is discussed which uses a combination of field monitoring data and a geomechanical model to evaluate and rank the effectiveness of different operational scenarios.
