Expedition 405 methods

LWD/MWD acquisition systems and tools Depth tracking systemLWD/MWD data are recorded as a function of time.The tool clock is synchronized with the clock inside the SLB Maxwell data acquisition system on board.The Maxwell system is used to communicate with and receive data from the tools downhole using continuous mud-pulse telemetry while Table T2.Position of LWD/MWD tool sensors within the BHA relative to the drill bit, Expedition 405.NA = not applicable.Download table in CSV format.Tool Offset from bit Hole C0019F depth (m) Hole C0019H depth (m) Hole C0026A depth (m) SonicScope (top) 32.42 31.86 31.63Delta-T 27.59 27.03 26.82 Receiver 12 28.1627.59 27.39 Receiver 11 28.05 27.49 27.28 Receiver 10 27.95 27.39 27.18 Receiver 9 27.85 27.29 27.08 Receiver 8 27.75 27.19 26.98 Receiver 7 27.65 27.09 26.88 Receiver 6 27.55 26.98 26.78 Receiver 5 27.44 26.88 26.68 Receiver 4 27.34 26.78 26.57Receiver 3 27.2426.68 26.47 Receiver 2 27.14 26.58 26.37 Receiver 1 27.04 26.48 26.27 TeleScope (top) 22.09 21.53 21.39 Orientation tool 18.07 17.05 17.26 Pressure 14.82 14.15 14.01 MicroScope (top) 13.93 13.22 13.07 GR 12.55 11.84 11.68 Resistivity 11.07 10.36 10.21 UHRI 10.15 9.44 9.32 Button 1 10.19 9.47 9.31 Button 2 10.18 9.46 9.30 Button 3 10.17 9.45 9.29 Button 4 10.16 9.44 9.29 Button 5 10.15 9.43 9.28 Button 6 10.14 9.42 9.27 Button 7 10.13 9.41 9.26 Button 8 10.12 9.41 9.25 Bit resistivity 4.91 4.63 4.56 Float sub 8.76 NA NA Motor 8.05 8.05 8.05 13.015 13.
