Permeability Enhancement by Dynamic Stresses
Together with Emily Brodsky and Jean Elkhoury we have been studying the effects of dynamic stresses on permeability of fractures. The work shows that pore fluid pressure oscillations significantly enhance fluid permeability of fractured sandstone.
We are pursuing the physics of the processes involved and the implications of permeability enhancement for flow in Earth’s crust, including oil and gas production and subsurface sequestration of CO2. A manuscript was submitted to Nature Geoscience, March. 2009
