Introduction to April Focus: Induced Seismicity

Wendell Pardasie

Microseismic monitoring in the oil and gas industry is the process whereby typically low magnitude seismic events (below ~1 moment magnitude) are detected and located in the subsurface during hydraulic fracturing utilizing downhole, surface or shallow subsurface arrays. Many definitions have used wording such as small scale or micro earthquakes… continue reading.

Injection-Induced Seismicity: End of the Beginning?

Shawn Maxwell

For the last several years there have been numerous technical workshops on injection-induced seismicity which, looking back, serve as snapshots documenting the rapid evolution in our understanding of this important topic. With time, the tone of these workshops has changed in step with advancement by industry, regulators and academics managing… continue reading.

Ranking Operation Scenarios for Effective Mitigation of Hydraulic Fracture-Induced Seismicity

Shawn Maxwell, Devin Garrett, Paige Mamer and Atena Pirayehgar

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. 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… continue reading.

Economics of Induced Seismicity: Trying to identify faults in the horizontal well planning stage

Brian Wm Schulte

“Induced seismicity” refers to a seismic event that is caused by pore pressure and stress change associated with human activity (Boroumand and Maghsoudi, 2016). The maximum magnitude of induced earthquakes is smaller than what is seen with natural earthquakes (Metz et al., 2017); they tend to occur in swarms (Metz et… continue reading.
