Figure F36. Summary of LWD measurements, Hole U1378A. GVR = geoVISION tool, ARC = arcVISION tool, PEF = photoelectric factor, IDRO = image-derived density, RHOB = bulk density, RING = resistivity measured by the ring electrode (geoVISION tool), P16B = phase-shift resistivity measured at a 16 inch source–receiver separation (arcVISION tool), A40B = attenuation resistivity measured at a 40 inch source–receiver separation (arcVISION tool).
