OIL & GAS

Increased efficiency leading to reduced cost is key:
OFG provides surveys throughout the oil field life cycle to enable robust decision making for Exploration, Development, Production/Inspection and De-commissioning  

  • Reservoir characterization for prospect evaluation, ranking and step out exploration
    • ​Our Towed Streamer EM system allows rapid and efficient collection of CSEM data
    • Multiphysics workflows that integrate CSEM with seismic and other information lead to better characterization of sub-surface structure and properties ​
  • Deep towed CSEM can be used for characterization of gas hydrate and shallow gas deposits
  • P-Cable (3D UHRS) for reservoir imaging

EXPLORATION

DEVELOPMENT

  • P-Cable (3D UHRS)
    • Geohazard and route surveys
    • Field development
  • AUVs equipped with state-of-the-art survey and navigation suites including Synthetic Aperture Sonar (SAS), SBP, MBES, magnetometers (SCM), geochemical sensors, laser scanners and high resolution colour cameras
  • Digital twin/ 3D Whole earth models allowing engineers, geoscientists, and regulators to extract information and quantify risk from a single unified model
  • AUV non-contact pipeline inspection:  

  • ROV/HAUV non-contact infrastructure inspection:   

    • iCP mounted on an ROV or HAUV can be used for efficient inspection of subsea infrastructure in oil & gas and offshore renewables 

  • P-Cable (3D UHRS) for 4D reservoir monitoring and investigations

PRODUCTION / INSPECTION

  • Site survey 

    • High resolution mapping of infrastructure (pipes, cables, debris) and geohazards by AUVs (SAS, SBP, SSS, MAG)

    • High resolution AUV CSEM: characterise shallow sub-surface sediment, fluid properties and contamination
