Conference paper
We present an application of 3D VTI visco-acoustic frequency-domain full waveform inversion (FWI) based on sparse direct solver on wide-azimuth OBC data from the Valhall oil field. Mono-parameter inversion for the vertical wavespeed is applied to the hydrophone component in the 3.5-10Hz passband. Compared to reflection traveltime tomography, we...
