77 2. Surface geophysical methods information from the seismic data. This also ensures consistency between seismic and CSEM derived results, which is important for subsequent integrated interpretation. In this way, vertical (Figure 2.17b, upper panel) and horizontal (Figure 2.17b, lower panel) resistivity were recovered. Good RMS residual was achieved insuring that such recovered resistivity model honored the data. Vertical resistivity for the unconstrained and constrained inversions run are shown in the interval of interest: the top one (Figure 2.17c, top) corresponding to the unconstrained (a) (b) (c) Figure 2.17 mCSEM example from the Hoop area of the Barents Sea. After Alvarez et al. (2017). (a) mCSEM data in the frequency domain (amplitude (top) and phase (bottom)), (b) recovered resistivity results by seismically constrained inversion (vertical resistivity (top) and horizontal resistivity (bottom)), (c) vertical resistivity for the unconstrained (top) and seismically constrained (bottom) inversions run shown in the interval of interest.
