The nonlinearities in the inverse problems related to travel-time, generalized travel-time and amplitude matching during production data integration were investigated. The results were demonstrated using a field application involving a multiwell, multitracer interwell tracer injection study in the McCleskey sandstone of the Ranger field, Texas. It was shown that the travel-time sensitivities are more uniform between the wells compared to the amplitude sensitivities that tend to be localized near the wells. The results show that commonly used amplitude inversion can be orders of magnitude more non-linear compared to the travel-time inversion.
