Technique for stabilizing fresh core samples encapsulated within the inner tube

Fluid Pipe for preservation of shale
Fluid Pipe for preservation of shale

The Fluid Pipe is a suitable solution for transporting rock samples, such as shale, immersed in mineral oil or other fluids. This technique ensures structural integrity is maintained, protects it from external elements, and enhances the quality of sampling

GeoBag Sealing and Vacuuming
GeoBag Sealing and Vacuuming

Geobag protects your geological samples from external chemical elements through vacuum-sealing or heat-sealing methods, making it ideal for medium to large storage periods

PTFE/PVC strips for core stabilization

The GeoShim is inserted into the annulus to fix the piece of drill core and fractures. Easy to handle and easy to remove in the laboratory, different sizes and material (PTFE / PVC) are available in order to guarantee perfect stabilization effect.

Waxing encapsulation with Geoseal

Melting equipment and paraffin wax for rock preservation: Ensuring fluid saturation and preventing selected samples from drying during prolonged storage before laboratory analysis

What is core preservation, and why is it important?

Core preservation is a critical aspect of the mineral collecting and exploration process, the foundational practice in field geology, particularly in structural geology, where maintaining the pristine condition of mineral samples is paramount. This practice ensures that the invaluable data derivative from these samples (obtained using rock coring drills and other geological field tools) accurately reflects the original geological formations. As part of mineral exploration and field geology, core preservation secures the integrity of these samples, preventing the potential data distortion that could arise from even the little changes during the recovery, handling, or transportation processes.


How does core alteration during borehole handling affect the analysis?

Furthermore, core alteration during downhole handling (a stage that uses various geological tools) is a critical concern, as it directly impacts the fidelity of data used for analyzing the structural geology and the petrophysical properties of the subsurface. As such, the integrity of fossil field storage is equally important, ensuring that the core remains representative of the reservoir’s original conditions. Therefore, swift and careful handling, complemented by a thorough understanding of the core recovery processes and strategic use of field geology best practices, is essential to preserve the core’s integrity for subsequent analysis.


How does Geofactory approach core preservation for various environments?

Geofactory’s innovative approach to core preservation encompasses various environmental contexts within the Oil & Gas, mining, geotechnical, and earth science sectors. They implement tailored solutions, leveraging specialized geological tools and rock coring drills, to ensure that the structural and compositional integrity of the drill rock samples is undamaged. This commitment to meticulous core preservation supports the advancement of mineral exploration and the accurate analysis of mineral samples.

What are the objectives and challenges of core preservation during shipment and storage?

The core preservation objectives and challenges during shipment and storage encompass a broad scope of field geology practices. The methods deployed seek to protect the core’s sequence and prevent structural damage, which is paramount for soft or poorly consolidated cores often found in mineral exploration. Relevant preservation techniques include managing environmental factors to avoid dehydration, salt precipitation, and oxidation. Transport and storage processes can worsen the condition of mineral samples. To this end, swift and strategic measures are taken, such as minimizing headspace in fossil field storage containers to prevent evaporation and condensation, thus ensuring the continued validity of the core for detailed petrophysical analysis.
