OFG Performs CSEM Gas Hydrate Survey in Japan


Ocean Floor Geophysics (OFG), in cooperation with Fukada Salvage and Marine Works, has completed a high resolution CSEM survey of near surface gas hydrates.

The survey was performed using the Scripps Institution of Oceanography Vulcan system for the National Institute of Advanced Industrial Science and Technology (AIST) in Japanese waters. 

The survey comprises over 500 line kilometers of high resolution data collected using the Fukada vessel Shin Nichi Maru. Water depths range from 400 to 1100 meters.

A 3D inversion of the EM data for an area of interest has been completed. The contract for the 3D inversion of the data for the entire survey area has also been awarded to OFG and will be completed in November this year. Fukada Salvage and Marine Works acted as prime contractor.
