Processing and Attribute Analysis of Low-frequency Blackfoot Data

This paper examines the utility of Seismic Unix for processing and attribute analysis of low frequency seismic data. The data were acquired in July 1995 by the Consortium for Research in Elastic Wave and Exploration Seismology (CREWES) in Blackfoot, Alberta. The data are processed using Seismic Unix and the resulting migrated seismic section is compared to the results of previous processing done by a contractor. The quality of the migrated seismic section processed using Seismic Unix is comparable to the one done previously using commercial software. An exact comparison is not done because the two processing flows differ due to availability of advanced processing modules in open source software. After processing, instantaneous seismic attributes are computed, which help with interpretation and can be used as parameters for quality assurance of the final processing results.
