SUMMARY:CAE Seminar- Dilatant Hydro-Shearing Fracture Growth - Theory & Observations- Brice Lecampion
UID:641296@northwestern.edu
TZID:America/Chicago
DESCRIPTION:Abstract- This talk explores the mechanics of fluid-driven frictional ruptures\, accounting for frictional weakening\, dilation\, and permeability changes. While primarily occurring during hydraulic stimulation of geothermal reservoirs\, these processes also impact fault stability\, landslides\, and glacier mechanics. Assuming a circular rupture geometry\, we examine how the rupture propagation behavior can widely varies with rock properties\, in-situ conditions\, and injection protocols. Finally\, we revisit the Basel-1 well stimulation\, presenting a dilatant hydro-shearing model that replicates the injection sequence. We discuss the model's agreement with observed pressure and microseismic evolution\, while addressing uncertainties in key parameters like horizontal stress and frictional properties.  Bio- Brice Lecampion is currently Associate Professor and the head of the Geo-Energy Lab at EPFL\, Switzerland. His research aims at understanding the interplay between the growth of localized discontinuities (in the form of fractures and faults) and fluid flow in geomaterials with applications in the field of environmental\, civil & resources engineering\, and earth sciences at large. Prior to joining EPFL\, Brice worked for Schlumberger in research and development from 2006 until May 2015 - serving in a variety of roles ranging from project manager to principal scientist in both Europe and the United States\, working on CO2 storage as well as unconventional hydrocarbon well stimulation. Dr Lecampion received his PhD in mechanics from Ecole Polytechnique\, France in 2002 and worked as a research scientist in the hydraulic fracturing research group of CSIRO division of Petroleum resources (Melbourne\, Australia) from 2003 to 2006.
