Unique Technologies for your Challenging Sea Floor Projects

OFG provides high quality geophysical data, analysis and sea floor characterisation services for exploration and investigation. We provide data acquisition and analysis services that were previously unavailable by combining our specialised expertise in subsea operations, sensor design and sensor integration with geophysical technologies beyond the scope of traditional marine geophysical surveys. These include magnetic, EM, CSEM/MT, VCS, and AUV gravity surveys deployed on ROVs, AUVs and deep tow systems to give you a new perspective and confidence to make informed decisions for your offshore exploration and development projects. 

As an experienced user of advanced electromagnetic and potential field inversion codes OFG provides interpretation services for the data it acquires. We provide complete 3D models to visualise and interpret diverse data that includes geological, hydrographic, and geophysical components. Shown below is an integrated model of a 3D magnetic inversion, bathymetry and OFG EM seafloor conductivity model. The model illustrates several zones of low magnetic susceptibility below the Solwara 1 deposit. These are interpreted to be feeder systems below the mineralization characterised by magnetite destruction due to hydrothermal alteration.
