Notes: Used when the tool is slipping (no rotation). Fluid pulse telemetry frame while not rotating (slipping) = update rate at 6.0 bps. ROP = rate of penetration (m/h). PP = PowerPulse MWD tool, GVR = geoVISION resistivity tool, SVWD = seismicVISION while drilling tool, sonic = sonicVISION while drilling tool, ADN = Azimuthal Density Neutron tool (adnVISION). CO = coherence, TT = traveltime.
