Time-lapse multicomponent geophone and DAS VSP processing and analysis
Various geophone and distributed acoustic sensing (DAS) vertical seismic profile (VSP) datasets acquired in south central Texas are processed for P-wave and PS-wave imaging. The surveys acquired and analyzed in this project were time-lapse zero-offset and walkaway recorded on both geophones and DAS, and a 3D survey recorded only by DAS. This project focuses on reprocessing and analyzing the various datasets to evaluate the differences between the geophone and DAS VSP surveys and to analyze the time-lapse changes from hydraulic fracturing. The DAS performs comparably to the geophones and records ...
