Special Geophysics Seminar 2017 SEG Lecture
October 19, 2017 @ 3:00 pm - 4:00 pm
Speaker: Mirko van der Baan, University of Alberta
“How Widespread is Human-Induced Seismicity in the USA and Canada?”
There has been significant public and scientific interest in the observation of changed seismicity rate in North America since 2008, possibly due to human activities. We find that the seismicity rate in Oklahoma between 2008 and 2016 is strongly correlated to increased hydrocarbon production. The possibility of systematic correlations between increased hydrocarbon production and seismicity rate is a pertinent question since the United States became the world’s largest hydrocarbon producer in 2013, surpassing both Saudi Arabia’s oil production and Russia’s dry gas production. In most areas, increased production is due to systematic hydraulic fracturing which involves high-pressure, underground fluid injection.
