    Our origins

    Four names, one continuous story

    GEOSIGMOID GROUP is the product of fifteen years of organic growth, in which several companies and corporate identities came together as one group.

    • Since 2011From a first venture to an integrated group
    • Dubai and TunisRegistered office in Dubai, office in Tunis
    • Four service linesSubsurface studies, field operations, software and training
    1. 2011

      GO GEOENGINEERING

      Our first venture: software development and petroleum field studies, with a focus on exploration and development.

    2. United States

      GEOSIGMOID LLC

      Our second corporate identity, created in the United States.

    3. 3GEO

      3GEO ARIN

      A geoscience and reservoir company named after its three disciplines: geology, geophysics and geomechanics.

    4. Today

      GEOSIGMOID GROUP

      3GEO ARIN renamed: one continuous history under the name we carry today.
