Figure F41. Caliper and total gamma ray logs, Hole U1413C. LCAL = hole diameter measured by the Hostile Environment Litho-Density Sonde (HLDS), C1 and C2 = hole diameters measured in orthogonal directions by the Formation MicroScanner (FMS), HSGR = total gamma ray curve measured by the Hostile Environment Natural Gamma Ray Sonde (HNGS) in the FMS and Ultrasonic Borehole Imager (UBI) tool strings, p1 = logging pass 1, p2 = logging pass 2. For more information on tool and curve descriptions, see the “Methods” chapter (Harris et al., 2013).
