Early-arrival waveform inversion: Application to cross-well field data

Xukai Shen, Tieyuan Zhu, and Jerry M. Harris


We apply early-arrival waveform inversion to a cross-well field data in order to find the extent of a potential reservoir that terminate somewhere between the two wells. Ray-based tomography result is too smooth to resolve the boundary. On the other hand, waveform inversion is able to better utilize the advantage of short wavelength cross-well data, resulting in a velocity model that defines the potential reservoir boundary more sharply. Details from the waveform inversion result are verified by well-log data.
