his EAGE E-Lecture, titled "Geometrical Inversions with Integration of Geological Modeling", presents and tests a method in which automatic geological modeling is integrated into level-set inversion. The objective of this method is to enhance geological realism during deterministic geophysical inversion, particularly for modeling interfaces between rock units. To achieve this, a geological correction term is introduced in the model update to reduce geological inconsistencies at each inversion iteration. This is made possible through the integration of an automatic, implicit geological modeling scheme within the geophysical inversion algorithm. After introducing the main theoretical aspects of the approach, a realistic synthetic case is presented to demonstrate the proof of concept in a basin scenario using gravity data. Results indicate that this approach effectively guides inversion towards geologically consistent models, suggesting its potential applicability to field data.
