Ocean Floor Geophysics Ltd. (OFG) completed a high resolution CSEM survey of near surface gas hydrates using the Scripps Institution of Oceanography Vulcan system for the National Institute of Advanced Industrial Science and Technology (AIST) in Japanese waters.
The survey includes more than 500 line km of high resolution data collected using the Fukada vessel Shin Nichi Maru.
Water depths were from 400 to 1100m. 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.
The survey was in cooperation with Fukada Salvage and Marine Works Co. Ltd., who were prime contractor in the project.
