Figure F116. Comparison of natural gamma ray values at the Unit III/IV boundary, Site C0002. A reference baseline of 75 gAPI is included on all LWD gamma ray curves. From left to right: caliper measurement in Hole C0002A (blue line = bit diameter, red line = maximum operational borehole diameter for the LWD tool); LWD gamma ray curves for Holes C0002A, C0002G, and Hole C0002F; whole-round multisensor core logger (MSCL-W) natural gamma ray measurements from Hole C0002B (black dots) and C0002J (red dots) cores; and natural gamma ray measurements from Hole C0002F cuttings.
