Introduction to VALEM for GM-SYS 3D: High performance gravity inversion for subsalt imaging
In this introductory video, Ian MacLeod, chief technologist, presents VALEM (Voxel Assisted Layered Earth Modelling), a new cloud-powered inversion service that seamlessly integrates with GM-SYS 3D, Geosoft's powerful layer-based 3D modelling software program.
VALEM resolves the base of salt from gravity data bound by the constraints of seismic modelling. It uses a unique hybrid approach that incorporates grids, geosurfaces, and 3D voxels for more accurate representation of salt geometry and sub-salt density distributions versus traditional modelling methods.
Learn how VALEM:
- Harnesses the power of Geosoft's most advanced 3D inversion technology deployed in a high performance computing (HPC) cloud to solve large problems quickly
- Enables interpretation teams to iterate and collaborate through different constraining scenarios maximizing the value of gravity data to obtain the best possible integrated models
