Sonde is taken up while rature logging
WebLogging while drilling (LWD) tools take measurements in much the same way as wireline-logging tools, except that the measurements are taken by a self-contained tool near the … WebAnswer: This is done to maintain constant tension on the wire. The tools themselves do not “know” what depth they are at, and indeed, depth control is one of the big challenges we have when drilling / logging wells. When running a wireline tool downhole, the tension is, by nature, going to vary...

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 … 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. Log plotting requires a depth-tracking system and additional surface …
