Geomage is an international firm that specializes in the creation and supply of cutting-edge technologies tailored for seismic data processing and interpretation. Additionally, it provides a variety of software solutions and services to numerous companies within the oil and natural gas sectors. The company’s seismic-processing offerings are grounded in the groundbreaking MultiFocusing™ technology, which has been deployed across countless exploration locations worldwide, ensuring precise imaging and enhanced detail regarding subsurface structures and stratigraphy. Among its array of tools, the g-Viewer stands out as a powerful instrument for visualizing and selecting seismic datasets within a three-dimensional environment. The commercial version of this viewer supports the plotting of both 2D sections and volumetric data, thereby enriching the experience for its users. By integrating advanced features, the g-Viewer enhances the analytical capabilities of geoscientists and engineers alike.

OpendTect software consists of two primary segments: an open-source portion that is accessible at no cost and a closed-source segment that requires a commercial license through FlexNet. The open-source part, called OpendTect, functions as a seismic interpretation system that supports both 2D and 3D seismic data, promoting the swift creation of new interpretation tools. Users can expand the functionality of OpendTect by employing various complimentary plugins. In contrast, the closed-source section, known as OpendTect Pro, provides a more sophisticated version with enhanced features tailored for professional users. Additionally, OpendTect Pro supports the incorporation of commercial plugins, enabling specialized seismic interpretation workflows that are not present in the free version. This blend of open-source adaptability and commercial improvements positions OpendTect as a highly flexible option for geoscientists and industry experts. As a result, both segments cater to a wide range of user needs and preferences, further solidifying OpendTect's reputation in the geoscience community.
