The goal of this research line is to establish simple links between geological models and the physical processes involved in several indirect subsurface measurements (e.g., reservoir production, deformations, waveforms, gravity anomalies, etc). Controlling the level of detail and consistently simplifying the geomodel is essential to ensure efficient and accurate physical computations such as flow simulation.

The accurate representation of geological features in the computational support is an essential aspect of this research. This motivates the use of unstructured meshes, which can adapt to complex geological features and technical objects such as boreholes while offering local adaptiveness. An important aspect of RING research concerns the generation of these meshes based on prior knowledge.

Because the needed level of detail and computational resources may vary from one application to another, we also do research on the scaling of petrophysical properties, both in unstructured and structured meshes.
