Plots by Xiaodong Ma and Mark D. Zoback showing the close correlation between in situ stress and lithology in Woodford Shale reservoir samples.
Research in the following areas is currently being carried in the Stress and Crustal Mechanics Group:
- Effects of depletion and injection on conventional and unconventional reservoirs
- Modeling, computation and applications of poroelasticity and poro-elastodynamics in fractured porous media
- Laboratory measurements of permeability and gas transport in shale reservoir rocks
- Fluid penetration measurements of shale gas for pore size distribution
- Micro- and nano-imaging of shale gas for porosity estimation and numerical permeability simulation
- Constrained geomechanical modeling of Marcellus shale gas reservoir rocks via hydraulic fracturing data and microseismicity
- Stimulation mechanisms of permeability in shale gas/tight gas/tight oil reservoirs including hydraulic fracturing, microseismicity, and slow slip on faults
- Multiplets as a tool for assessing hydraulic fracturing operations in shale reservoirs
- Viscoplastic deformation of organic-rich shales and its effect on rock properties, the state of stress, and the evolution of geologic structures
- Mapping of crustal stress orientations and relative magnitudes over the conterminous United States using in situ measurements, inversions of earthquake focal mechanisms, and emerging techniques
- Numerical modeling of the tectonic and geodynamic factors that control the intraplate stress field
- Assessment and management of risks associated with induced and triggered seismicity
- Developing a better understanding of the physics of fluid-induced earthquakes
