Abstract
Summary 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). 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 input data was minimally processed mostly through noise removal and the initial model was built via tomography with a strong smooth version of the tomographic update from a pre-stack migrated gather flattening process. During the EFWI, a multiscale approach was followed to ensure the convergence and the early stages of the / ratio was constrained by the mud rock-line ratio. The velocity fields were validated via 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.
