The topics above are offered by ICDP's Operational Support Group (OSG), a small team of scientists, engineers and technicians to assist in project planning and management. 

Downhole Logging

Consulting and service

Logging Truck

The offered support reaches from evaluation and support of planning and management of downhole logging programs within ICDP proposals to the actual performance of entire or parts of borehole logging sessions. Our assistance in preparation of borehole logging programs comprises check of availability of equipment & expertise, equipment acquisition and cost assessment. If desired the OSG can carry out downhole logging measurements with a special equipment fitting most ICDP operating conditions.

Logging operations

We performed 35 downhole logging campaigns in 21 ICDP projects in 18 countries since 1999.

    OSG performed downhole logging at 3 sites of the HSPDP project: 

    Baringo/Tugen Hills, Turkana and Magadi. 

    Difficult hole conditions at the Turkana site caused a stuck drill pipe and hence allowed cased hole logging only (GR/SGR & hole inclination).

    At Magadi the collapsing borehole wall prohibited a complete open hole logging set.

    OSG performed downhole logging at all 3 sites of the 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 in an 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 always stable and hence never got 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.

    OSG performed downhole logging in the major part of the 688 m (517 mblf) deep hole 1C. As downhole logging accompanied the ongoing drilling the hole was logged in four sections with a total of nearly 80 hours logging time distributed over 4 days. The sonic sonde was damged by the extremly low temperatures during transport of the equipment. The borehole was very stable due to bentonite mud treatment. Main target was to log the lake sediments and the transition to impact rocks.  All depths below are meters below drill rig reference, not lake floor. At the drilling site the water depth was at 171 m.

    OSG performed slimhole logging for the DAFSAM project. Total gamma ray and magnetic susceptibility was measured in three shallow holes drilled from a gallery at a depth of 3600 m in the ultra deep Tautona Gold mine. Two of the holes were inclined slightly upward and one downward. Motion of the sonde inside the holes was accomplished by pushing and pulling manually. The data acquisition system worked trouble free under the very hot and humid conditions in the deep mine.

    OSG performed downhole logging in the 2500 m deep crystalline rock borehole (open hole below 44 m) in several campaigns. The second campaign in late April/early May consisted of running the GFZ borehole geophone sonde, BG, for the seismics experiment in cooperation with the Univ. of Alberta, Doug Schmitt). IN 2008 aside logging runs we deployed the GBM Göttingen Borehole Magnetometer downhole. In 2011 beside logging we took several downhole fluidsasmples.
