Oasis montaj

Geophysical software for processing, filtering, and interpreting survey data.

Transform geophysical data into decisions  dots

Oasis montaj is industry-standard software for geophysicists to process, filter, and model geophysical survey data. It enables users to create reliable subsurface interpretations by integrating large geophysical datasets with other geoscience data in a user-friendly application. This software is ideal for geophysicists and geological survey bodies in the mineral resources, energy, environmental, or on/offshore infrastructure industries who require accuracy, power, and versatility.
