Fluid Induced Earthquakes: Insights from a Hydrogeologic Perspective
Dr. Shemin Ge, Department of Geological Sciences, University of Colorado Boulder

Beginning in the 1960s, pore fluid pressure was identified as the primary culprit for inducing earthquakes reported near deep fluid-injection wells. Induced seismicity has surged in recent decades in central eastern US, yet only a relatively small percentage of injection sites experienced seismicity. Questions arise with regard to what fundamental hydrogeologic and mechanical processes make some sites more prone to induced seismicity than others. This lecture will offer an overview and physical insights of fluid induced seismicity from hydrogeologic and poro-mechanical perspectives. Case studies in Oklahoma and Colorado will be used to illustrate how pore fluid pressure could have played a role in observed seismicity. High rate of fluid injection emerges as an important player in contributing to induced seismicity. While preexisting faults dictate earthquake locations, the spatial extent of pore pressure influence could reach tens of kilometers from fluid injection. Research is on-going to further understand the causal mechanism for induced seismicity and to provide scientific guidance for best practices in the quest for secure energy resource development in coming decades.
Shemin Ge is Professor and Chair in the Department of Geological Sciences at the University of Colorado Boulder. She received her Ph.D. from The Johns Hopkins University in 1990, subsequently worked at S.S. Papadopulos and Associates, and joined the University of Colorado in 1993. At the confluence of subsurface fluid flow physics and rock mechanics, Ge’s early research examined the effects of tectonic deformation on paleo-fluid flow systems in sedimentary basins. She moved on to explore earthquake-induced groundwater flow as natural experiments to reveal hydrologic properties of aquifers and explore the mechanisms of seismicity induced by reservoir operation and wastewater injection. Another thread of her research relates to groundwater resources and surface-groundwater interactions under a changing climate with a focus on headwater regions. She also ventured into fracture flow and fault zone hydrology, as well as subsurface thermal energy transport and storage.
Shemin Ge also served the hydrogeologic and broader geoscience communities in various capacities. She was Chair of the Hydrogeology Program Planning Group for the Ocean Drilling Program from 1999 to 2002. She was Editor for Hydrogeology Journal and Associate Editor for Geofluids and Journal of Ground Water. She recently served a two-year term as Program Director for the Hydrologic Sciences Program at the US National Science Foundation. She was the 2016 distinguished Birdsall-Dreiss lecturer for the Geological Society of America Hydrogeology Division.
LOCATION: The EPA Conference Center located on the 2nd floor of the EPA Region 8 Headquarters building at 1595 Wynkoop St. When entering the building, visitors will be asked by the building security guards to display valid photo identification, pass through airport type security machines, sign in at the lower front desk, and wear a temporary EPA visitor badge. Then please proceed to the second floor to register with the CEMS representative.
MEETING FORMAT: Members may either bring their own lunch and attend the meeting for no charge, or they may request that CEMS order a box lunch for them. The cost of the box lunch for members is $16.00; for non members, $19.00 (note price increase).
RESERVATIONS: PLEASE give your name, company name and phone number via email to email@example.com. PLEASE INDICATE IF YOU ARE RESERVING A BOX LUNCH OR BRINGING YOUR OWN. Reservations must be received BEFORE Friday, January 5, 2018 at 5:00PM. No reservations will be taken after this date! Payment of $16.00 for members, $19.00 for non-members will be accepted at the door with prior reservation. Please cancel your reservation by Friday, January 5, 2018 if you are unable to attend.
Learn where and how to use the state's water data by joining us for this how-to webinar. We'll train to use Colorado's Decision Support Systems (CDSS) and take a close look at the Division of Water Resources' HydroBase Data Viewer under the guidance of John Rodgers, DWR's HydroBase coordinator, and Chris Brown, DWR's GIS program manager. Log in over lunch, come ready to learn and bring your questions!
Wednesday, August 23rd
Starting at 5:00pm
Join your fellow CGWA associates for this year’s Summer Social at
Mountain Toad Brewing in Golden.
Visit with old friends, catch up on recent events, and meet some new members.
Mountain Toad Brewing is located at 900 Washington Ave.
Parking is available on Washington Ave., or after hours at the OnTap Credit Union lot next door or American Mountaineering Center lot across the street.
CGWA will have reserved tables in the outdoor patio area, weather permitting.
The association will provide appetizers and the first round of beers.
The food truck vendor, Jessie’s Smokin’ NOLA, is onsite for dinner options.
Please feel free to bring your spouse/significant other.
We look forward to seeing you there.
Those interested in tubing on Clear Creek in Golden prior to the event, contact Ralf Topper at firstname.lastname@example.org
Tubes & PFDs can be rented right next to the brewpub.
