Delivering sound structural geological models with valid geometries, present-day and at key moments in time

By integrating data in 3D digital space, section and 3D model construction

4DGeo is specialised in constructing internally consistent and valid present-day geological models, including geological sections and 3D-models by integrating a range of data types in digital 3D space and applying geometrical construction rules combined with an understanding of the geological and structural evolution.

By testing, validating and improving existing interpretations

Existing models are tested and validated (or not) using digital line-length, area and/or volume balancing techniques. A valid model need not be right, but a balance test rules out any impossible interpretations.  Concepts are tested using either restoration and/or forward modelling techniques. All this requires a good understanding of the structural geological history and tectonic setting.

By quantifying palaeo-geometry, basin shape, faults, fractures - linkage and flow paths..

.. at critical points in time.  Any valid geological model can be restored from deformation, to quantify palaeo-geometry and palaeo-linkage at key stages in the development of the system.  Which were the fluid-focussing pathways? What volume was the local topographic 'high'?  Where were the sealing layers or breaching faults?

By informed data collection, from drill core and the field, and by doing field checks of key structures to ground-truth modelled scenarios

Structural analysis is as good and as detailed as the quality and the usefulness of data that is collected, and requirements for structural data can be quite specific.

4DGeo is specialized in structural mapping and in setting up and logging of structures in oriented drill core, ensuring quality and completeness of data captured.
