Numerical and structural modeling in Earth sciences


Structural geological modeling
Structural models are computed using software developed at Terre+ to address the specificities of geological data (scarcity, density heterogeneity, uncertain data). A wide range of interpolation methods allows addressing each geological context according the appropriate process (kriging, splines, weighting…). The model is built in partnership with the geologists. It is delivered as powerful viewing software allowing the customers to fully benefit of their data (interactive sections, virtual boreholes, volumetric computations, movies…).

Meshing
As a link toward numerical modeling, structural models built at Terre+ can be exported and meshed in finite elements. Own specific tools are developed to address complex geometries in very large models.

Numerical modeling
Terre+ builds groundwater flow models that describe accurately complex hydrogeological systems. A wide experience of calibration allows to fully benefiting of Feflow 6® capabilities in coupled transport or polyphasic flows.

Uncertainties computation
Terre+ proposes an assessment of the uncertainties on both structural and numerical models, due to the lack of data or the spatial parameters variability. The uncertainty associated to the models makes them full decision making tools.
