In 2005 the Borehole Research Group of the Lamont Doherty Earth Observatory designed a temperature tool that could acquire data in combination with a Schlumberger tool string or as a stand-alone tool in memory mode. Schlumberger designed and provided the telemetry interface hardware. The tool measures borehole temperature and axial acceleration of the tool string, as well as power supply and reference voltages and internal temperature'.
The temperature data acquired with the MTT are depth-shifted and depth-matched during the processing of the standard log data. For a complete account, refer to the Standard Data Processing Notes.
Additional information about the drilling and logging operations can be found in the Operations and Downhole Measurements sections of the expedition report, Proceedings of the Integrated Drilling Program, Expedition 336. For further questions about the logs, please contact:
