RKT-160 X-ray Core Tomograph

X-ray Core Tomograph is intended for studying the internal structure of a rock sample without mechanical damage (cuts). The system gives a 3D distribution of the core density. The systems can work with core samples of various diameters, including fill-size core, in a non-invasive way, without taking it out its plastic container.

Core tomography is used to detect homogeneous and specific areas before special analysis. The quality and homogeneity of the selected samples can be additionally controlled by extra scanning. Results can be used to obtain a core density diagram and refer core density to well-log data.

• Interlayer thickness;
• Interlayer density;
• Interlayer inclination;
• Inclusion of ‘critical’ minerals (pyrite, barite, iron oxides);
• Inclination distribution of fractures;
• Specific surface of fractures;
• Volume of caverns/inclusions;
• Amount and distribution of gaseous hydrates in core.

To perform tomography, a core sample is placed in a rotating case, while fixed X-ray source and detector move along the core. X-ray detector registers data on X-ray projections of the core at all angles. After raying, projection data are processed to give a 3D density distribution. The whole process of raying and data processing is software-controlled.
