The application of waveform inversion to land data is even more challenging than the marine case because of strong elastic effects such as groundroll, near surface attenuation, scattering due to rapid geological variations and topography. In this paper, rather than considering full elastic waveform inversion which maybe too difficult for standard geophone data, we consider the application of acoustic 2D full waveform inversion with a frequency domain code. At lower frequencies, the data are very noisy so we carried out a fixed number of iterations with a small band of low frequencies and then repeated this for increasingly larger bandwidth. We present the results from this procedure, which show the waveform inversion improved the continuity of the main reflectors.
