Subsurface Flow and Coupled Processes: Cross-Scale Lab Investigations and Capability Development

April 27 @ 10:00 am - 11:00 am

Chun Chang, Energy Geosciences Division, Lawrence Berkeley National Laboratory What to Expect Subsurface flow affected by thermal, mechanical, chemical and other processes is of great interest to geological CO2 sequestration, spent nuclear fuel and waste disposal, shale oil and gas recovery and geothermal energy production, etc. The processes can be complicated by the formation heterogeneity and anisotropy, inducing great uncertainties in modeling predictions. This talk will focus on (1) pore-scale supercritical CO2-brine displacement in 2D heterogeneous micromodels, including mass transfer…

Fluid Injection Induced Rock Failure Under True Tri-Axial Stress Condition

April 24 @ 2:00 pm - 3:00 pm

Zhou, Xue Jun (John), Research Associate, Mewbourne School of Petroleum & Geological Engineering of the University of Oklahoma, Norman What to Expect After a short overview of the different types of laboratory tests that Dr. Zhou has conducted in the rock mechanic laboratory at the University of Oklahoma, the focus will be given to the tests of fluid injection induced rock (granite and schist) failures under true tri-axial stress condition. These tests revealed that fluid injection induced fractures are always…

Laboratory Study on Fracture Slip and Induced Seismicity by Fluid Injection

April 20 @ 10:00 am - 11:00 am

Zhi Ye, Mewbourne School of Petroleum and Geological Engineering, The University of Oklahoma What to Expect Shear reactivation of faults/fractures caused by pressurized fluid injection is quite important in many subsurface engineering problems and geological phenomena, such as reservoir stimulation, wastewater disposal, geologic carbon storage, and induced seismicity. Specifically, inducing fracture self-propping by slip has been viewed as an effective means of permeability enhancement in the development of subsurface energy, which has led to the concept of shear stimulation or…

DSSS: Isolating the Evolving Roles of Anthropogenic Aerosols and Greenhouse Gases in Regional Climate Change

April 17 @ 10:30 am - 12:00 pm

Clara Deser What to Expect The Community Earth System Model “initial-condition Large Ensemble” has been widely used to disentangle forced climate change from internal climate variability at regional scales. Here,we introduce a complementary set of experiments to study the individual roles of greenhouse gases and anthropogenic aerosols in the evolution of multi-decadal trends since 1920, with a focus on large-scale patterns of precipitation and sea surface temperature. Aerosols from industrial sources and biomass burning are the primary driver of forced trends before the mid-1970s,…

EGD Colloquium: Roland Gritto

April 1 @ 1:00 pm - 2:30 pm

Roland Gritto What to Expect Seismic tomographic imaging relies on P-wave and S-wave velocities to  delineate geological subsurface structures. In contrast, the ratio between seismic P-wave and S-wave velocities (Vp/Vs) is more sensitive to fluid saturation. Vp/Vs-ratio has been utilized in numerous studies to distinguish liquid from gaseous fluids in the Earth’s subsurface. Studies include seismic exploration of gas and oil reservoirs, imaging of fluids in fault zones, investigations of volcanic regions to delineate and track movement of liquids (melt)…

Experimental Insights into the Seismic Response of Single Fractures

March 27 @ 11:00 am - 12:00 pm

Harrison Lisabeth, Postdoctoral Research Fellow Speaker Bio Harry Lisabeth is currently a Postdoctoral Research Fellow in the Energy Geosciences Division at Lawrence Berkeley National Laboratory (LBNL). He received AB’s in Geological Sciences and Literary Arts from Brown University in 2010 and a Ph.D. in Geology from the University of Maryland, College Park in 2016. His graduate work focused on the effects of chemistry on rock deformation. From 2016 to 2018 he was a Postdoctoral Research Fellow at Stanford University working…
