Density logging tool
The tool itself initially consisted of a radioactive source and a single detector, but this configuration is susceptible to the effects of the drilling fluid. In a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors. In a 2 detector configuration, the short-spaced detector has a much shallower depth of investigation than the long-spaced detector so it is used to measure the effect that the drilling flu… WebJan 18, 2024 · The density tool measures the apparent density of the formation using a radioactive source that bombards the formation with high energy gamma rays and then measures the number of lower energy gamma rays returning to the detectors. The detectors and source are mounted in a pad that is forced against the borehole wall.

A density-logging tool sends gamma rays into a formation and detects those that are scattered back. Typical logging sondes use a Cesium-137 source, which emits gamma rays of 0.66MeV. At this high energy level, Compton scattering dominates. The average electron density in the volume of … See more In the standard sequential interpretation process, the analyst determines porosity directly from the density log. It is conceptually the easiest of the porosity logs to interpret … See more In addition to gamma ray scattering, modern density tools also analyze the low-energy region of the scattered gamma ray spectrum separately. … See more Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read See more Unfortunately, Pe does not obey a linear, volumetric mixing law on which log analysis thrives.
