Inversion with acceleration data: Theoretical development and numerical implementation

Abstract

New acquisition technologies that measure more than one wavefield component at the streamers are now available. We analyze how the frequency of input data limits the resolution of the final image and introduce a method using acceleration data as input data to improve the resolution for full waveform inversion (FWI). The FWI using acceleration data is achieved by defining of the misfit function and the construction of gradient. Using synthetic data examples, we show that FWI with acceleration data has the potential to improve the resolution of the inverted model with an optimal rate of convengence.
