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
