Notes: LSF = LWD depth below seafloor. ROV = remotely operated vehicle. MWD = measurement while drilling, GR = gamma ray, APWD = annular pressure while drilling. TD = total depth. DRF = drillers depth below rig floor. LWD = logging while drilling, GVR = geoVISION resistivity tool, sonic = sonic while drilling (sonicVISION), SVWD = seismicVISION while drilling, MWD = measurement while drilling.
