Oasis montaj Basin Modelling
Oasis montaj Basin Modelling provides quantitative gravity and magnetic modelling, including forward modelling using explicitly defined subsurface geometry and physical properties.
It is used when gravity and magnetic data need to be interpreted through model‑based comparison, where calculated responses are evaluated against observed survey data to test and refine geological scenarios.
Geological, seismic, and well information is used to constrain the subsurface model itself, supporting structurally consistent interpretations and reducing reliance on visual correlation alone. While commonly used in basin and energy studies, the modelling approach can be applied across a wide range of geological settings and scales.
Oasis montaj Basin Modelling is one of three available subscriptions, alongside Base and Ultimate. Cloud‑based inversion services are available for projects that require large‑scale or voxel‑based inversion workflows.
