Figure F11. Wireline tool strings to be deployed at the Expedition 344 sites. A. Triple combo-UBI tool string takes downhole measurements of hole diameter, natural gamma ray, bulk density, electrical resistivity, and ultrasonic images of the borehole. B. FMS-sonic tool string measures borehole resistivity images, natural gamma ray, and P- and S-wave velocities. C. VSI tool string acquires seismic waveform data in a check shot experiment. LEH-MT = logging equipment head-mud temperature, EDTC = Enhanced Digital Telemetry Cartridge, HNGS = Hostile Environment Natural Gamma Ray Sonde, HLDS = Hostile Environment Litho-Density Sonde, HRLA = High-Resolution Laterolog Array, GPIT = General Purpose Inclinometry Tool, UBI = Ultrasonic Borehole Imager, DSI = Dipole Sonic Imager, MTT = Modular Temperature Tool, FMS = Formation MicroScanner, VSI = Versatile Seismic Imager. Except for MTT, all acronyms are marks of Schlumberger.
