This section describes how to build models in Leapfrog Geo.

  • Geological models can be built from lithology data or from any other suitable data in the project. Visualising data in the scene is an important step in determining the model that will be built, and the tools for doing this are described in Visualising Data. Once this has been determined, the next step is to define a basic geological model and refine its boundaries. Modelling contact surfaces and setting their cutting relationships determine how the basic model volume is divided into lithologies. Models can also have a fault system that, once activated, will subdivided the model into fault blocks.
  • With the Interpolants folder, you can interpolate downhole numeric data, composited drillhole data and points data.
  • Combined models use information from up to four geological models, interpolants and distance functions in order to visualise relationships between different types of data in the project.
  • Geological models created in Leapfrog Geo can be used as the basis for ModFlow and FEFLOW models. You can create flow models directly in Leapfrog Geo and assign hydrological/material properties based on the lithologies in the geological model. Flow models can be exported for use in other applications, and you can import existing flow models and use them as the basis for the construction of new models. Flow models can be displayed in the scene, and time-dependent data can also be visualised.
  • Leapfrog Geo can import Isatis files and UBC grids. Block models and sub-blocked models can also be created directly in Leapfrog Geo and exported for use in other applications. Creating block models within Leapfrog Geo has the advantage that the resolution can easily be changed. Block models can be evaluated against geological models and interpolants as described in Evaluations.
