Notes: Used while the tool is rotating. Fluid pulse telemetry frame while rotating = update rate at 6.0 bps. ROP = rate of penetration (m/h). SVWD = seismicVISION while drilling tool, PP = PowerPulse MWD tool, RAB = resistivity-at-the-bit, sonic = sonicVISION while drilling tool, ADN = Azimuthal Density Neutron tool (adnVISION). CO = coherence, TT = traveltime.
