Characterization of geothermal reservoir crack patterns using shear-wave splitting
- Univ. of North Carolina, Chapel Hill, NC (United States)
Microearthquakes recorded by a downhole, three-component seismic network deployed around the Coso, California, geothermal reservoir since 1992 display distinctive shear-wave splitting and clear polarization directions. From the polarizations the authors estimated three predominant subsurface fracture directions, and from the time delays of the split waves they determined tomographically the 3-D fracture density distribution in the reservoir.
