Density log tool
WebJun 24, 2015 · The now-standard compensated neutron-porosity logging (CNL) tool, in common use since the 1970s, is still a very simple tool. Like a density tool, it consists of an isotopic source (now most often americium-beryllium, although at least one tool uses an accelerator source) and two neutron detectors. WebTrue. You are given the gamma ray log on a well which has been drilled through a siliciclastic sequence. The gamma ray reading of clean sand is 20 API units and the shale baseline has a reading of 120 API units. The Gamma ray Shale Index (IGR) is calculated to be 0.25. The Gamma ray reading across the formation is.

Density 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 porosity, the other two being sonic logging and neutron porosity logging WebIn neutron logging, some tools measure the epithermal neutrons, some the thermal neutrons and some ... density of pure water is 1.000 g/cm3.

WebDec 4, 2024 · Sonic logs. A sonic log is an acoustic log that emits sound waves which start at the source, travel through the formation, and return back to the receiver [1]. The travel time from the source to the receiver is called slowness and as a result sonic logs are sometimes referred to as sonic slowness logs.
