Abstract
A key limitation of waveform inversion as currently implemented is the need for a starting model of high accuracy or field data with low frequencies. Here we present a new approach – staged waveform inversion – designed to mitigate this need and thereby permit the application of waveform inversion to a much wider range of datasets.
