Bayesian inversion of multilayer migration from seismic plume observations using a graph-based finite-rate invasion-percolation model
Elling Svee, Jo Eidsvik, Kasper Hunnestad +1
Vertical migration of in layered sandstone reservoirs is controlled by thin shale barriers whose properties are often poorly known. We develop a Bayesian framework…

Agentic Scientific Simulation: Execution-Grounded Model Construction and Reconstruction
Knut-Andreas Lie, Olav Møyner, Elling Svee +1
LLM agents are increasingly used for code generation, but physics-based simulation poses a deeper challenge: natural-language descriptions of simulation models are inherently under…

Non-stationary Spatial Modeling Using Fractional SPDEs
Elling Svee, Geir-Arne Fuglstad
We construct a Gaussian random field (GRF) that combines fractional smoothness with spatially varying anisotropy. The GRF is defined through a stochastic partial differential equat…
