With the frontier areas of hydrocarbon exploration moving to more challenging geological settings, decisions based on seismic methods alone could be risky. Independent information from alternative geophysical methods integrated with seismic data becomes essential and necessary in this challenging situation. We consider an approach of integrating the complementary information of different geophysical methods to obtain self-consistent geophysical models based on using joint focusing stabilizers in regularized joint inversion of multiphysics data. The method enforces strong coupling between different models and promotes the sharp boundaries of the targets. The practical effectiveness of the developed methods is demonstrated by the case study of integrating and imaging electromagnetic (EM) and full tensor gravity gradiometry (FTG) data collected in the Nordkapp Basin in Barents Sea, Norway.Keywords: Multiphysics, marine, electromagnetics, gradiometry, multiparameterPermalink: https://doi.org/10.1190/segam2021-3581155.1FiguresReferencesRelatedDetails First International Meeting for Applied Geoscience & Energy Expanded AbstractsISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2021 Pages: 3561 publication data© 2021 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 01 Sep 2021 CITATION INFORMATION Xiaolei Tu and Michael S.
