WebThe small but significant differences between drill pipe depth and logging depth should be taken into account when using the logs for correlation with core and log measurements. Core measurements such as susceptibility and density can be correlated to the equivalent downhole logs using the "Sagan" program, which allows shifting of the core depths onto …
Web7.1 Well Logging. Well logging is an evaluation method in which a logging crew lowers a special tool, a sonde, into the well and then pulls it back up. As the sonde passes the formations on its way up the wellbore, it senses and measures electrical, radioactive, and acoustic (sound) properties of the rocks. WebJun 24, 2015 · Nuclear logging while drilling. Gamma ray measurements have been made while drilling since the late 1970s. These measurements are relatively inexpensive, although they require a more sophisticated surface system than is needed for directional measurements.
