Speaker: Luigi Bianco, PhD Student in Applied Geophysics, University of Naples Federico II
I will discuss of a joint inversion method for potential fields aiming at recovering reliable models of complex source distributions, as those involving either shallow or deep-seated bodies. In this case, anomalies are characterized by different wavelength-contents, so that we may try to invert jointly the field and its higher-order vertical derivatives. To accomplish this task, we adopt a sequential strategy with a cross-gradient constraint. I will focus on the importance to incorporate different types of a-priori information (softer or harder constraints) to better address the ambiguity. The softer constraints include the model weighting function. On the other hand, we introduced harder constraints in the form of a reference model, which allows introducing other information from geology, previous geophysical interpretations or from well logs. The strength of the method is the applicability on a very wide range of applications.
Speaker Biography: Luigi Bianco, PhD Student in Applied Geophysics, University of Naples Federico II
Luigi Bianco received the M.Sc. degree in geology and applied geology with a curriculum studiorum in applied geophysics at University of Naples Federico II, Naples, Italy, in 2021. He is enrolled in the Earth, environment, and resources sciences Ph.D program at University of Naples Federico II. His research interests include potential fields modeling, multiscale potential field analysis, and joint inversion of geophysical datasets. He is an active SEG member serving as past-president and field co-lead at the UniNA student chapter and as member of the European Regional Advisory Committee and University and Student Program Committee.
