WebJun 24, 2015 · Nuclear-logging tools exploit only two types of radiation: gamma rays and neutrons. Both follow basic scattering principles but have unique reaction types and cross sections. ... Density tools and neutron-porosity tools simply measure the drop-off in radiation with distance from the source of radiation. While this can be done with a single ... WebDensity logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole.In geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces.This is one of three well logging tools that are commonly used to calculate … people shooting a m1a

WebLithology Density (TLD) and Micro-Cylindrically Focused Log (MCFL) measurements are integrated in the single pad of the High-Resolution Mechanical Sonde (HRMS), which … 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… WebApr 5, 2024 · The density–neutron log is a combination log that simultaneously records neutron and density porosity. In some zones, porosities recorded on the logs differ for … peoples home mortgage lending
