is designed for bulk density quantification and rock formation effective atomic number determination within oil/gas open holes.
- it is to be run with a logging station equipped with digital recorder “Vulkan” and others, to provide recording and storing downhole data in a digital code “Manchester-2”
- processing method provides near-field effects compensation (mudcake thickness up to 20 mm) and referenceless source energy scale temporary variability accounting
- density quantification and rock formation effective atomic number determination provide rock lithology determination according for 3- component model
- the equipment has a field calibrator for bulk density and effective atomic number
