Density log tool
WebApr 24, 2013 · 5. Definition Density logging is a well logging tool determining rock bulk density along a wellbore. 5. 6. Geologically, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the enclosed volume of free fluids (porosity). Density is one of the most important pieces of data in formation evaluation. 6. 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.

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. WebThe density log measures electron density by detecting gamma rays that undergo Compton scattering. The intensity of scattered gamma rays is proportional to electron …
