UNSTRUCTURED MESH
Real data need real models
At Geotexera, unstructured (triangular and tetrahedral) meshes are used for geophysical inversions and modellings. This new technique allows us to easily and accurately add borehole information, geological contacts, high-resolution topography, and surfaces (generated by Leapfrog and GOCAD,...) to our models to obtain reliable results.
GEOPHYSICAL INVERSION
Today, in mineral, oil&gas, water, geotechnical and environmental explorations, new problems and challenges need new and modern solutions. We use different advanced geophysical inversion (independent, joint and constrained) methods to image and reconstruct geological structures from geophysical data (such as magnetic, gravity, gravity gradiometry, magnetotelluric and first arrival travel-time seismic data).
FORWARD MODELLING
Forward modelling is one of the methods for interpretation in which geophysical data will be synthesized based on physical properties and geometries. This method can help us find the size and contribution of geological structures in geophysical data.
MACHINE LEARNING
Machine learning methods can be used for producing (or improving) geological maps as well as predicting subsurface resources. For this purpose, we use both unsupervised and supervised machine learning methods on geophysical, geochemical, radiometric, geological and remote sensing data.
A Brief Review of tools and methods
(We use all of them to provide you with the most reliable results ...)
MESHES
Unstructured meshes (triangular for 2-D and tetrahedral for 3-D)
Rectilinear meshes (the old conventional one)
We prefer and recommend (new) unstructured meshes not only because of their higher accuracy but also it is time to move on to real models!
