Abstract

Summary

We present marine magnetotelluric (MT) results from data extracted from multiple controlled source electromagnetic (CSEM) surveys using a new multi-station processing code with a highly automated workflow. The quality of the MT response estimates processed with multi-station processing are dependent on the subset of receivers (i.e. stations) that is processed together, and the subset of available receiver-data recording time intervals selected for processing. Historically these steps have been manual and very time consuming. The MT workflow described in this paper replaces these manual steps with automated receiver grouping and data-driven algorithms for locating the expected best subset of time intervals for processing.

This code has produced high-quality MT data over a wide range of geological settings. Two case studies are cited, an example of MT processing results from Espirito Santo, a deep water basin offshore Brazil and 2D MT inversion of lines set together from multiple CSEM surveys, acquired over several years in the Hoop area in Barents Sea, Norway.
