Abstract:
We present a depth to basement case study which incorporates knowledge of magnetotelluric inversion uncertainty into the final interpretation.
Inversion with Occam2D and rj-McMC was conducted for over 1600 magnetotelluric sites from the Isa Extension MT survey in western Queensland. The combination of 2D deterministic inversion and 1D probabilistic inversion offered surety that the 2D data were being modelled adequately, and provided a means of estimating inversion uncertainty. Synthetic modelling was also used to establish the resolvability of the basement interface based on the resistive character of the project area; derived from downhole resistivity data.
