N2 - Resistivity logs have been used by seismic interpreters for many years to construct seismograms, particularly in hydrocarbon gas fields where sonic logs are scarce or absent. The correlation between the conventional synthetic seismogram made from density and sonic logs and the pseudo-synthetic seismogram made from density and resistivity logs has not been very satisfactory in the past because many of the pseudo-synthetic seismograms do not include the gas effect. Our research team has developed a method to correct for the gas effect, and thereby to improve the overall quality of the pseudo-synthetic seismogram. We apply this method to a well and then compare the improved results to a conventional seismogram made from the same well. Our research should be of interest to researchers in New Zealand, Taiwan and other Pacific Rim countries because of the similarities in the tectonic setting of these nations.
