DESCRIPTION:Abstract\n\nEnhanced geothermal systems (EGS) differ from conve
 ntional reservoirs in that fractures and faults are central to the enginee
 ring problem. The coupled physical processes governing faulted and fractur
 ed reservoirs are complex and difficult to model. Traffic light systems (T
 LS)\, the current state-of-the-art for managing induced seismic hazard\, h
 ave shown only limited success\, in part due to fundamental limitations as
  reactionary protocols operating in stochastic systems.  \n\nIn this prese
 ntation\, I address two questions that are critical to scaling up EGS: \n\
 n1. Can we leverage the permeability structure of fault zones to optimize 
 geothermal energy? \n\n2. How can we develop transferable models and forec
 asts of fluid-induced fault slip? \n\nTo address the first question\, I pr
 esent an in-depth analysis of the most recent stimulation at Fervo Energy
 ’s Cape Station in Utah\, demonstrating that large-scale faults form cor
 e components of the stimulated network. Next\, I develop a probabilistic f
 ramework for seismic hazard management and embed it within a feedback cont
 rol loop to design optimal injection strategies.  \n\nThe presentation hig
 hlights the importance of explicitly accounting for the geomechanical cont
 act problem and argues for a shift in perspective on pre-existing faults: 
 from treating them as a liability to recognizing them as a central design 
 variable in future geothermal systems. \n\n \n\n\n\nBio\n\nTaeho Kim is a 
 postdoctoral scholar at Stanford University in the Department of Energy Sc
 ience & Engineering\, working with Professor Eric Dunham in the Department
  of Geophysics. His research focuses on developing computational models of
  enhanced geothermal systems\, with an emphasis on the coupled interaction
 s between hydraulic fractures\, pre-existing faults\, and fluid pressure e
 volution. He also works with Prof. Hamdi Tchelepi on numerical implementat
 ions of sophisticated friction laws in GEOS for multiphase flow settings.\
 n\nPrior to Stanford\, he received his B.S. in Civil Engineering from the 
 University of Michigan and his M.S. and Ph.D. in Applied Mechanics from Ca
 ltech. His doctoral thesis\, Modeling Frictional Processes in the Presence
  of Fluids: From Earthquakes in the Laboratory to Induced Seismicity in Ge
 othermal Reservoirs\, received the Demetriades Award for Outstanding Thesi
 s in Seismo-Engineering\, Prediction\, and Protection.\n\nHe currently ser
 ves as co-leader of the Statewide California Earthquake Center’s initiat
 ive on Advancing Simulations of Earthquakes and Aseismic Slip\, where he l
 eads community efforts to develop numerical benchmark problems for fault s
 lip coupled with pressure diffusion driven by subsurface fluid injection.\
