Since the 2022 workshop, induced seismicity continues to occur in Texas (Permian Basin, EagleFord) and in numerous locations across the globe. The first session of the workshop will set the scene by highlighting recent induced seismicity studies in context of earlier examples over the last decade.

Chairs: Shawn Maxwell, Ovintiv; Cody Comiskey, Chevron              

Keynote Presentation: A Systematic Review of the Life Cycle of Injection Induced Seismicity

Research and Learnings in the Montney Trend: Impacts to the Regulatory Landscape

Since the first injection-induced earthquakes were recognized, the research community has developed a strong understanding of their causal mechanisms. However, questions remain about the relative importance of triggering factors such as poroelastic stressing and loading by aseismic slip on faults. In addition, the occurrence of induced earthquakes associated with carbon storage and enhanced geothermal systems raise questions about triggering mechanisms in a range of operational environments. This session summarizes research on these triggering factors for induced earthquakes, with the goal of improving understanding of the governing physics and relative significance of each causal mechanism in various operational settings.

Monitoring changes in reservoir pressure is key in understanding cases of injection-induced seismicity, and is particularly important in systems that are challenging to model such as those with anisotropic permeability fields and multiple injection locations. This session will be a panel discussion format covering topics such as progress in monitoring and understanding pressure changes in the subsurface, use of pressure data in calibration of models, changes in regulatory requirements of pressure data, and case studies showing best injection practices as determined from pressure data.

Moderators: Katie Smye, University of Texas at Austin; Hannah Chittenden, Diamondback Energy; Michelle Gaucher, BCER

Panelists:

• Jean-Philippe Nicot, Center for Injection and Seismicity Research, Bureau of Economic Geology, UT Austin    

• Murray Dighans, Endeavor Energy Resources

• Jeff Thompson, Oxy

• Jamie Rich, Coterra

   

This session will feature posters on injection-induced seismicity topics invited and contributed from researchers, operators, regulators, and service companies. Posters will include a broad range of topics, including operational site characterization, causal factors of induced earthquakes, case studies of induced earthquake sequences, operator and regulator responses and mitigation strategies, and others.
