Progress And Issues In Single Well Seismic Imaging Available to Purchase

Over the last five years as part of DOE''s Fossil Energy Program, Lawrence Berkeley National Laboratory (LBNL), in conjunction with industry, has been developing and applying methods of extending the penetration of conventional seismic logging from a few meters out to tens if not hundreds of meters. The use of borehole seismic sources and sensor strings, capable of exciting frequencies from 10s to 1000s of Hz, on a single cable is termed single well seismic imaging (SWSI). The SWSI acquisition work within our project has progressed through various field tests to a current system capable of CMP type borehole surveys with multiple borehole source and receiver options. Recent field experiments have been aimed at salt dome imaging from wells within and outside of a salt dome.
