GeoModeller is an advanced 3D geological modeling software developed by Intrepid Geophysics in collaboration with the French Geological Survey . It enables geoscientists to construct complex, implicit 3D geological models by integrating diverse data types, including geological contacts, orientations, drillhole data, geophysical surveys, and structural inferences. The software's geostatistical vector field interpolator allows for the creation of detailed geological interfaces and fault networks, even with sparse datasets. GeoModeller is widely utilized across various sectors such as mining, oil and gas, geothermal energy, hydrogeology, and engineering, facilitating comprehensive subsurface interpretations and decision-making processes.
Key Features and Functionality:
- Implicit 3D Geological Modeling: Utilizes a geostatistical vector field interpolator to build 3D geological models constrained by primary geological data, including contacts and orientation data.
- Drillhole and Data Management: Offers full support for drillholes and attributed data, with interpolation methods such as domain kriging to mimic geological formation shapes.
- Geophysical Modeling and Inversion: Performs forward and inverse modeling of potential field geophysics directly from 3D geology, supporting gravity, magnetics, full tensor gradiometry, and airborne EM data.
- Geothermal Modeling: Computes forward heat flow modeling integrated with the 3D geological modeling engine.
- Advanced Fault Network Management: Manages complex fault networks and stratigraphic piles through rule-based modeling, ensuring accurate representation of geological structures.
- Mesh and Grid Management: Provides tools for 3D grids/mesh calculation, adaptive tetrahedral meshing, and visualization, enhancing the analysis of geological models.
Primary Value and User Solutions:
GeoModeller addresses the need for accurate and efficient 3D geological modeling by integrating various geological and geophysical data into a cohesive framework. Its implicit modeling approach allows for rapid construction and revision of geological models, accommodating new data seamlessly. By offering tools for forward and inverse geophysical modeling, GeoModeller enables users to validate and refine their geological interpretations, reducing uncertainty and improving decision-making in exploration and resource management. The software's comprehensive functionality supports a wide range of applications, from resource estimation and drillhole management to geothermal and hydrogeological studies, making it an invaluable tool for geoscientists aiming to understand complex subsurface geometries and optimize exploration strategies.
