Recent computer computational improvements have allowed us to simulate elastic data in a 3D manner and undertake the challenge to execute elastic full waveform inversion (EFWI). For the field data experiment to demonstrate the technologies, we elected to use a Gulf of Mexico (GOM) ocean bottom cable (OBC) data-set which allowed us to take advantage of relatively large offsets along with the four component acquisition. The velocity fields were validated through imaging algorithm of the elastic reverse time migration and the imaging shows clear structural improvements when inputting the inverted velocities in conjunction with the measurements.
