[MIS16-03] Deployment of logging while drilling at hydrothermal fields in Okinawa Trough: Preliminary results of CK16-01 Cruise
Keywords:Okinawa Trough, Cross-ministerial Strategic Innovation Promotion Program (SIP), Logging While Drilling, Seafloor hydrothermal Deposit, Iheya-North Knoll, Iheya Minor Ridge
The LWD tools acquire natural gamma ray, resistivity, borehole images, and annular pressure and temperature data. Based on the results from the CK14-04 cruise in 2014 at the Iheya-North Knoll, LWD was useful to identify and characterize the submarine hydrothermal deposits and the LWD survey enhanced the successful recovery of sulfide samples. In this presentation, we report the preliminary results of LWD deployed during the CK16-01 Cruise.
