Snake River Plain Geothermal Play Fairway Analysis Project active source seismic data archive Lee Liberty, Research Professor Department of Geosciences Boise State University Boise, Id 83725-1535 lliberty@boisestate.edu 208-426-1166 (phone) This archive contains seismic shot field records for 10 profiles located in Camas Prairie, Idaho The eight numbered .sgy files were acquired using a seismic land streamer system with an accelerated weight drop source and 72 geophones. These 10-Hz geophones were mounted on base plates and dragged behind the seismic source. Shots were acquired every 4 meters along the length of 500West, 550 West, 600West, 700West, 800West, 900West, 200South and 200North. The objective was to map stratigraphy and structures related to geothermal fluid flow in the upper few hundred meters. 200North_shots_geom.sgy 200South_shots_geom.sgy 500West_shots_geom.sgy 550West_shots_geom.sgy 600West_shots_geom.sgy 700West_shots_geom.sgy 800West_shots_geom.sgy 900West_shots_geom.sgy Two additional seismic profiles (Bakstrum and Barron) were acquired across farm fields between 200South, 700West, and 500West. These data were instrumental in siting a new geothermal well in southern Camas Prairie. Bakstrum_shots_geom.sgy Barron_shots_geom.sgy UTM coordinates are included in the seismic headers, and any industry standard seismic processing software can read these files and headers. Thus, source and receiver position information is included both in the Camas_Seismic_Master.xlsx (excel) spreadsheet and in the seismic field record files. I have included pdf images for each stacked profile. These final stacks were produced with a standard seismic processing flow that included: datum statics, spiking deconvolution, bandpass filtering, surface wave attenuation through a two-step singular value decomposition approach to estimate and adaptively subtract the ground roll signal, iterative velocity analyses with dip moveout corrections (dmo), amplitude gains, Kirchoff time migration, and a post-stack time to depth correction using dmo-corrected stacking velocity values.
