Yves Guglielmi is a staff scientist at the Lawrence Berkeley National Laboratory. His principal interests cover fundamental research in the hydromechanics of fractured and faulted rock. He focuses on the in situ understanding of the relationships between hydraulic, elastic and strength properties, rheology and induced seismicity of faults and fractures through field observation.  Yves Guglielmi is developing downhole probes to measure fault movements as close as possible to the natural and artificial fluid injection sources. Applications of his research concern giant rock landslides, and geo-energy (nuclear waste disposal, reservoir seal integrity and deep geothermal energy). He has been the Principal Investigator of several national and international programs on CO2 storage in deep reservoirs and on giant landslides in the European Alps. Now at LBNL, he is involved in  induced seismicity analyses, in developing new downhole instruments to optimize stimulation protocols in Geothermal fields and in the better understanding and monitoring of fault leakage, dealing with the loss of integrity of reservoir/caprock systems and of host rocks for nuclear repository projects.

Abstract

Scientists have known since the late 1960s that injecting fluids underground can cause earthquakes if those fluids find their way into slip-prone fault zones. Evidence of fluid-induced quakes has continued mounting in recent years with observations of abnormally high levels of seismicity in the central U.S. and in many other countries, coincident with increased injection of wastewater — mostly related to oil- and gas-mining operations — into the ground. But understanding the inner workings of fluid-filled faults is challenging because researchers have largely been limited by how close they can get to study them. This talk is offering a glimpse into the future of induced-seismicity studies by monitoring fault motions on the spot and in real time.
