2. Start Model Test
ZTEM inversions require a suitable priori resistivity starting model – usually the
representative average/bulk resistivity for the survey area. The correct choice
ensures the proper depth estimates for inversion models. When ground or borehole
resistivity data are unavailable, the choice can be estimated using a range of
starting models. The final model with smallest input error suggests the most optimal
choice of half-space resistivity. We have tested 02 lines L1000 and T2020 with
various start models for frequencies 90 to 720Hz. The results are summarized in the
table below. On average, the 5000 ohm-m start model needs the smallest input
error.
