Seismic Soundoff

Leo Eisner discusses his Honorary Lecture, "Mapping pore pressure with beach balls." The stress field of the Earth's crust has been studied for many decades as a part of seismology and geomechanics. Traditional stress inversion methods utilize focal mechanisms of earthquakes as this is typically the only data available at a regional scale and lower crust. With earthquake mechanisms, it's possible to reconstruct principal stress directions and a ratio of principal stress magnitudes but not the full stress tensor. However, combining data from reservoir injections and focal mechanisms from induced microseismicity overcomes this limitation. In this talk, Leo will show how they applied joint stress inversion to a geothermal and unconventional dataset and illustrate how microseismicity can be used to map pore pressure. In this conversation with host Andrew Geary, Leo breaks down the perfect audience for this lecture and the insights attendees will take away. Leo highlights how the bad attitude of a manager inspir
