is designed for bulk density quantification and rock formation effective atomic number determination within oil/gas open holes.

 

Description

Features and Advantages:

• its to be run with a logging station equipped with digital recorder VULKAN and others, which 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 determining according to 3-component model;
• the equipment has a field calibrator for bulk density and effective atomic number.

Downhole tool can be run with three-core logging cable.

Delivery set: downhole tool, technological and applied software.
