Local {3D} meshed geomodel updating: method and first results to assess the impact of stratigraphic unconformities in {CO2} sequestration.

in: 2022 {RING} {Meeting}, pages 21, ASGA

Abstract

In subsurface modeling, limited resolution and gaps in subsurface data may call for simulating unseen, but potentially important geological objects, and then assess their likelihood using physical simulation. For this, we propose to locally insert a geological interface in a meshed geomodel to avoid the burden of rebuilding the entire mesh. Our approach is based on the level-set discretization method, developed by the Mmg community, that generates high-quality meshes conformable to an implicit surface embedded in a 3D volume.
