Grid-Free Surface-based reservoir modelling
"My geology is too complex for my grid"
Surface-based modelling is a new approach to modelling subsurface heterogeneity and flow simulations. Surface-based reservoir modelling uses a boundary representation approach in which ALL heterogeneity of interest (structural, stratigraphic, sedimentological, diagenetic) is modelled by its bounding surfaces, independent of any grid. This allows efficient creation of geological models without the limitations of pre-defined grids (goodbye to stairstepping, pinchout cells, connectivity loss and fine-to-coarse grid upscaling).
SKETCH-BASED GEOLOGICAL MODELLING
Creating models of the subsurface can be a time-consuming and challenging effort. When testing out different hypotheses, scenarios or geological interpretations, such long and slow workflows are not the ideal tool to use. Rapid Reservoir Modelling (RRM) is a software tool that allows to sketch geological interpretations in 3D to quickly produce a model/prototype of the features of interest. Key static and dynamic parameters (volumetrics, partitioning, time-of-flight) are then computed to assess and compare the impact of e.g. the current interpretation or well patterns. New prototypes can be sketched and results computed within minutes.

Previous Research projects
Designing geothermal WELl representation for Surface-based modelling
Flow simulation of surface-based reservoir models with dynamically adaptive meshes requires accurate well representations. The challenge was to design a well representation that is flexible to capture any complex well trajectories and branching of (multi)laterals, while also being preserved as computational meshes are updated throughout simulations. This was originally set up for geothermal reservoirs, but is applicable to any type of flow simulation.
Storm scours in Arab-D
Rudstone-filled scours in the Jurassic Arab-D Mb. are likely to have an important impact of flow behaviour. We studied outcrop analogues in Saudi Arabia to understand the origin of these deposits and quantify their geometry and related facies distribution (see results here). The impact on flow behaviour is tested by implementing these results into surface-based reservoir models for flow simulation, a new approach to create grid-free geologically-realistic models
