InSAR Ground Displacement Analysis, Gary Oppliger and Mark Coolbaugh. This project supports increased utilization of geothermal resources in the Western United States by developing basic measurements and interpretations that will assist reservoir management and expansion at Bradys, Desert Peak and the Desert Peak EGS study area (80 km NE of Reno, Nevada) and will serve as a technology template for other geothermal fields. Raw format European Space Agency (ESA) ERS 1/2 satellite synthetic Aperture Radar (SAR) radar scenes acquired from 1992 through 2002 are being processed to measure the study area's time-dependent surface displacement patterns. Four of the ERS 1/2 SAR radar scenes used in FY04 were acquired through the Western North America InSAR (WinSAR) research consortium and additional scenes are being purchased from ESA. To create the required interferograms, we have configured an InSAR processing capability utilizing Jet Propulsion Laboratory's (JPL) Repeat Orbit Interferometry Package (ROI PAC) version 2.2.2 and ENVI post-processing tools. This processing work is in its mid-stages and will continue into FY05. Geothermal production summaries have been compiled to allow analysis of spatial and temporal changes to the reservoir. In FY05, existing surface geology and gravity defined basin geometries and structures from recent studies in the Bradys Desert Peak area will be combined with production data in a Geographic Information System (GIS) for comparisons with the derived InSAR patterns.
