Abstract

A case study is presented which illustrates the benefit of including isochron analysis when analyzing amplitudes influenced by tuning. Since tuning influences the waveform, it also influences the isochron measured from a nearby event to the target. The model which explains the amplitude anomaly must also explain the isochron variation. The approach presented here is a fast and simple way to corroborate more sophisticated methods such as impedance inversion, and to compare the likelihood of various model scenarios.
