The pulsed neutron-gamma density logging technique is used to measure the bulk density of formations based on the detection of gamma rays from the inelastic scattering of neutrons in the formations. However, the induced gamma ray source is regarded a

Formation density is one of the most important parameters in formation evaluation. Radioisotope chemical sources are used widely in conventional gamma-gamma density (GGD) logging. Considering security and environmental risks, there has been growing i

Accurate acquisition of elemental standard spectra is one of the key links in geochemical elemental logging. Because elemental standard spectra are affected by borehole and formation characteristics, it is necessary to study the borehole and formatio

In geochemical elemental logging, the elemental sensitivity factor is a key parameter for converting relative yields of elements obtained from spectral analysis to actual concentrations of the elements in the formation. Here we perform a quantitative

A numerical simulation of logging while drilling density (LWD) is investigated by using Monte-Carlo (MC) method. The response of azimuth imaging is performed with in a highly deviated well with 60 degree slope. And then, the influence of counting rat
