OSG performed downhole logging at all 3 sites of the SRSDP Hotspot drilling project: Kimberly, Kimama, Mountain Home (AFB). The borehole geophone chain 'Slimwave' (SW, 4 levels) was applied at Kimberly and Kimama together with equipment of the U of Alberta (vibrator truck & surface geophones). At MH the single borehole geophone of UofA was run on the OSG cable. At Kimama OSG used the downhole fluidsampler FS for the first time inn ICDP project. Especially the Kimberly borehole was logged in steps with the drillstring used as protection against potentially collapsing borehole wall. The OH sections were never blocked for wireline sondes. The Kimama hole was blocked for wireline sondes at 1219 m, later at 1138 m. The Mountain Home OH section was never blocked for wireline sondes.
