3D gravity and gravity gradiometry modeling, inversion and migration


TechnoImaging's EMVision®1 provides 3D modeling, 3D inversion and the only 3D migration services for entire gravity and gravity gradiometry surveys, including the following survey types:

  • Airborne
  • Ground
  • Borehole
  • Submarine

EMVision® can be used to simulate or interpret gravity and/or gravity gradiometry data for exploration and appraisal models, and/or dynamic reservoir models.

TechnoImaging has developed gravity and gravity gradiometry case studies to demonstrate how it is practical to rigorously invert entire gravity and gravity gradiometry surveys for 3D density models with millions of cells within a day. This enables multiple inversion scenarios to be explored so as to minimize 3D model uncertainty.

EMVision® incorporates TechnoImaging's focusing regularized inversion that enables the recovery of models with sharp density contrasts, rather than models with smooth density distributions.

EMVision® also enables Internet-hosted 3D gravity and gravity gradiometry modeling, inversion and migration on TechnoImaging's high performance computing resources.

EMVision® supports Geosoft and ASCII data formats, and industry standard earth model formats used by Petrel2, GoCad/SKUA3, Oasis montaj4 and encom pa.

TechnoImaging is able to provide short courses and training on 3D gravity and gravity gradiometry modeling, inversion and migration.
