The success of projects in almost all geoscientific disciplines depends crucially on the understanding of the structural conditions in the subsurface. Compared to two-dimensional maps and profiles, 3D models offer a significant gain in knowledge, as they allow the different geological rock layers and fault systems to be consistently constructed and visualized. A 3D geological model thus provides a robust basis for a number of applications, e.g. in the field of oil, gas and ore deposits, geothermal projects, groundwater development or engineering geological issues.

We create 3D subsurface models with the software GeoModeller (INTREPID), which has a high functionality. The internal construction logic follows geological rules and enables a robust and consistent modeling even if only a few interpolation points or geological and geophysical datasets are available.

Core functions of model building are: 

• Presentation and construction of geological layer boundaries and fault systems

• Integration of digital terrain models

• Integration of geological maps and sections as well as geophysical profiles

• Visualization of drill holes including drill paths

• Integration of well data (core data, logs)

• Generation of geological boundaries via integrated interpolation functions

• Adaptation of the generated surfaces to depth information from interpolation points

• Iterative model changes according to current state of art

• Flexible import and export functions for all common formats

The 3D models created in this way enable a visualization of the underground structures in all spatial directions. Integrated functions for mesh generation allow easy export of the 3D model into numerical models for further processing.
