Three-dimensional Compressional- and Shear-wave Seismic Velocity Models for the Southeast Geysers Geothermal Field, California
نویسندگان
چکیده
Three-dimensional compressionaland shear-wave velocity (“Vp” and “Vs,” respectively) structure is obtained for the SE Geysers geothermal area from microearthquake arrival-time data. The results indicate a region of high Vp and high Vs in the northwest portion of the area studied, and a low value of VpNs at depths corresponding to the upper part of the steam reservoir. The Vp and Vs anomalies are found to be well-modeled by the predicted seismic signature of the felsite intrusion.

Shear and Compressional Wave Velocities along with other Petrophysical Logs, are considered as upmost important data for Hydrocarbon reservoirs characterization. Shear Wave Velocity (Vs) in Well Logging is commonly measured by some sort of Dipole Logging Tools, which are able to acquire Shear Waves as well as Compressional Waves such as Sonic Scanner, DSI (Dipole Shear Sonic imager) by Schlumbe...
متن کاملThree-dimensional anatomy of a geothermal field, Coso, southeast-central California
This paper reviews geophysical and seismological imaging in the Coso geothermal field, located in southeast-central California. The Coso geothermal production area covers 6 10 km. Although regional seismicity is addressed, as it sheds light on the magma, or heat, sources in the field, the primary focus of this paper is on the main production area. Three-dimensional inversions for Pand S-wave ve...
متن کاملP Wave Velocity Variations in the Coso Region, California, Derived From Local Earthquake Travel Times
Inversion of 4036 P wave travel time residuals from 429 local earthquakes using a tomographic scheme provides information about three-dimensional upper crustal velocity variations in the Indian Wells Valley-Coso region of southeastern California. The residuals are calculated relative to a Coso-specific velocity model, corrected for station elevation, weighted, and back-projected along their ray...
متن کاملMicroearthquake Monitoring at the Southeast Geysers Using a High-resolution Digital Array
Microearthquake activity at the Southeast Geysers, California, geothermal field is monitored with a highresolution digital seismic network. Hypocenters are spatially clustered in both injection and production areas, but also occur in more diffuse patterns, mostly at depths from 1 to 2.8 km. Hypocenters near the injection well DV-11 exhibit a striking correlation with movement of injectate and i...
متن کاملTime-dependent Seismic Tomography of Geothermal Systems
Temporal changes in seismic wave speeds in the Earth’s crust have been measured at several geothermal areas, notably The Geysers in California, in studies that used three-dimensional seismic tomography. These studies used conventional tomography methods to invert seismic-wave arrival time data sets for different epochs independently and assumed that any differences in the derived structures ref...
