报告摘要：
Induced seismicity accompanying fluid injections is a topic of increasing interest because of the information that can be obtained from studying it and because of the risk it occasionally brings to surrounding populations and infrastructure. I will present a case study of induced seismicity into a depleted oil reservoir located offshore Spain. The seismicity began soon after injection started and continued well after the injection was terminated. It culminated in a series of Magnitude 3.8 – 4.2 earthquakes that occurred several weeks after injection was terminated. I will discuss new analysis of the seismic data and the modeling of the geomechanical response of accompanying flow and subsequent shut in period that allow us to better understand the nature and possible causes of the seismicity.
报告人简介：
Michael Fehler received his Ph.D. in seismology from MIT in 1979. He is currently a Senior Research Scientist in the Department of Earth, Atmospheric, and Planetary Sciences at Massachusetts Institute of Technology. He was Project Manager for two projects of the SEG Advanced Modeling consortium that are focused on geophysical modeling. He was Editor-in-Chief of the Bulletin of the Seismological Society of America for nine years beginning in 1995 and president of the Seismological Society of America from 2005-2007. He has coauthored a book on seismic wave propagation and scattering that was published in 1998 and a second edition of the book in 2012. His interests include seismic imaging, reservoir characterization, seismic scattering, geothermal energy, and induced seismicity.
