Delivering sound structural geological models with valid geometries, at present-day and 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 cross-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 restoration and/or forward modelling techniques. All this requires an in-depth 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, and targeted field checks of key structures to ground-truth modelled scenarios

    Structural analysis is as good and as detailed as the quality of the underlying data, and requirements for structural data to be useful can be quite specific. 4DGeo is specialized in structural mapping and in setting up a system for the logging of structures in oriented drill core, ensuring quality and completeness of collected data.
