1D Stochastic Inversion of Airborne Time-domain Electromag-netic Data with Realistic Prior and Accounting for the Forward Modeling Error
Peng Bai, Giulio Vignoli, Thomas Mejer Hansen
Airborne electromagnetic surveys may consist of hundreds of thousands of soundings. In most cases, this makes 3D inversions unfeasible even when the subsurface is characterized by…
Reconstruction, with tunable sparsity levels, of shear-wave velocity profiles from surface wave data
Giulio Vignoli, Julien Guillemoteau, Jeniffer Barreto +1
The analysis of surface wave dispersion curves is a way to infer the vertical distribution of shear-wave velocity. The range of applicability is extremely wide going, for example,…
Multiple-point statistical simulation for hydrogeological models: 3-D training image development and conditioning strategies
Anne-Sophie Høyer, Giulio Vignoli, Thomas Mejer Hansen +3
Most studies on the application of geostatistical simulations based on multiple-point statistics (MPS) to hydrogeological modelling focus on relatively fine-scale models and on the…
New regional stratigraphic insights from a 3D geological model of the Nasia sub-basin, Ghana, developed for hydrogeological purposes and based on reprocessed B-field data originally collected for mineral exploration
Elikplim Abla Dzikunoo, Giulio Vignoli, Flemming Jørgensen +2
Reprocessing of regional-scale airborne electromagnetic data (AEM) is used to build a 3D geomodel of the Nasia sub-basin. The resulting 3D geomodel integrates all the prior pieces…
(Quasi-)Real-Time Inversion of Airborne Time-Domain Electromagnetic Data via Artificial Neural Network
Peng Bai, Giulio Vignoli, Andrea Viezzoli +2
The possibility to have results very quickly after, or even during, the collection of electromagnetic data would be important, not only for quality check purposes, but also for adj…
Inversion of multiconfiguration complex EMI data with minimum gradient support regularization: A case study
Gian Piero Deidda, Patricia Diaz de Alba, Giuseppe Rodriguez +1
Frequency-domain electromagnetic instruments allow the collection of data in different configurations, that is, varying the intercoil spacing, the frequency, and the height above t…
