Impedance joint inversion of surface and borehole seismic data

Summary Impedance inversion of surface seismic data is a non-unique problem and the resolution is limited by the bandwidth of the seismic data. Make full use of the high frequency seismic information of borehole seismic data and the geologic information to constrain the impedance inversion is a better choice to improve these problems. With the sparse-spike inversion assumption, we set up an impedance joint inversion framework with the surface seismic and borehole seismic data. The surface seismic data, the borehole seismic data and the well logging data have been integrated into the joint inversion workflow to get a reasonable impedance inversion result. The high resolution inversion impedance with these multiple geophysical datasets is beneficial to improve the reservoir characterization. Two typical borehole seismic datasets were selected to joint inversion with the surface seismic data and the higher resolution of the impedance inversion result was presented respectively.
