Software combining 3-D forward and inverse modeling, interactive visualization and interdisciplinary interpretation of potential fields and their applications under geophysical and geological data constrains.


What IGMAS+ can do for you

IGMAS+ is a gateway to modern geophysical interpretation, where unraveling the complexities of the Earth’s subsurface demands an interdisciplinary approach and cutting-edge software capable of wrangling diverse and intricate data types.

In a realm where various types of data: seismic, gravity, full tensor gradiometry, magnetic, magnetotelluric come together in complex geological settings, IGMAS+ emerges as the ultimate solution. It's the art of merging constraint-driven data with independent subsurface information inside a 3-D framework combining numerical forward and inverse modeling of potential fields and their derivatives together with interactive visualization.

What sets IGMAS+ apart is its remarkable efficiency and user-friendliness. It enables interactive adjustments to the geometries and physical properties of modeled subsurface entities, all while visualizing the calculated and measured potential field components alongside independent observations.

IGMAS+ Graphical User Interface

IGMAS+ excels in areas with strong lateral seismic velocity and density contrasts, effectively addressing the associated imaging challenges. In particular, it has been successfully applied in sub-salt and sub-basalt environments.
