FLAC2D

FLAC2D, Fast Lagrangian Analysis of Continua, is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions. FLAC is used for analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project that requires continuum analysis. FLAC utilizes an explicit finite difference formulation that can model complex behaviors, such as problems that consist of several stages, large displacements and strains, non-linear material behavior, or unstable systems (even cases of yield/failure over large areas, or total collapse).

Geology by Seisware

Geology by SeisWare places traditional geologic interpretation tools, including tops picking and log correlation, into a dynamic 3D environment. Any changes in interpretation are immediately reflected in 2D and 3D space, with structural surfaces and zone interval maps updating on the fly. Dynamic cross sections can be moved through the reservoir to check for accuracy and consistency in interpretations. Best of all, Geology is fully integrated with Geophysics by SeisWare, for a complete sub-surface interpretation solution.

GeoModeller

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.
