Creating The Premier Energy Data Company

PGS and TGS have merged to form a pioneering data and services company in the energy sector, serving customers across the energy value chain and positioning itself as a strategic partner for energy companies. Explore our vision. 


These large and modern 3D datasets are created using public and PGS-owned 3D data that has been fully reprocessed as a single volume from field data in time and/or depth. They are an added-value product and a popular choice for energy companies exploring more mature hydrocarbon areas.

This is an ideal choice in mature areas with existing fields and infrastructure, offering opportunities to step out and explore in a nearfield setting.

Extrapolation away from existing assets is easier, to identify analogs and map prospects in more established hydrocarbon provinces, using these sizeable 3D volumes. MegaSurveyPlus datasets benefit from consistent processing using raw field output, as well as pre- and post-stack products. Many of the latest imaging workflows are applied, producing a seamless merge over a larger area.  

Regional Availability

MegaSurveyPlus is currently available in northwest Europe, Africa, and the Gulf of Mexico.
