GEO Resources – Introducing Data Processing Services, In Partnership With GEOTOMO


GRCI’s imaging center is located in Muscat, Sultanate of Oman (Head Office).

GRCI’s dedicated Data Imaging Center builds upon years of combined imaging experience. Together with our partner, we offer high-end geophysical software products that provides advanced data processing services that help geophysicists around the world to image the near-surface and subsurface in areas with rough topography and complex near-surface, and complex subsurface.

To address these complexities, our products include TomoPlus; near-surface imaging & statics solutions, GeoThrust; seismic data processing system, VECON; VSP and surface seismic modeling and survey design, MiVuTM; microseismic processing system.

Our software effectively manages the latest field recording acquisition techniques within the data processing workflow, to apply specific de-blending techniques.

Our Ethos Is Based Around Four Core Principals

Safety, Expertise, Accuracy & New Technology

Geo Resources has grown rapidly to become a global leader in exploration services to the oil and gas industry, developing proprietary on-line geophysical training platforms for our clients, along with remote QC software which is capable of analysing the technical integrity of all seismic instrumentation and sources.

Use of the latest technologies, techniques and software ensures optimal accuracy and reliability providing solutions for challenging projects, however remote, anywhere in the world. We believe that in our industry high operational standards are essential, not only for the longevity and reputation of our business, but for the environments in which we work and for the consistent delivery of cost-efficient services.

Delivering the best possible outcome to our clients is paramount, whatever the problems faced. We also attach special importance to direct cooperation and effective communication with each client in order to ensure the clearest
understanding of every stage of the service provided.
