Geotech S wireline core barrels for reliable deep drilling

Wireline core barrels are widely used in mining exploration and geotechnical drilling. They allow fast core recovery without removing the entire drill string. This method significantly improves productivity during deep drilling operations.

The Geotech S is a robust solution within our range of core barrels. It is designed for demanding drilling conditions and depths often exceeding 100 metres. Thanks to its modular design, it ensures both reliability and flexibility on site.

Designed for geotechnical and mining applications

The Geotech S wireline core barrels are especially suited to geotechnical investigations, mineral exploration, and ground assessment projects. They provide consistent core recovery while reducing downtime between runs.

This system supports accurate sampling, even in complex ground formations. The inner tube can be retrieved quickly using an overshot, which protects core quality and limits disturbance.

Available lengths and modular configuration

The Geotech S range is available in two standard lengths to suit different drilling requirements:

• 1,500 mm core barrel
• 3,000 mm core barrel

Inner tubes can also be ordered separately. This option simplifies maintenance and allows quick replacement in the field. Operators can therefore adapt their wireline core barrels to changing project needs.

Complete System and Accessories

The Geotech S system is available as a complete wireline core barrel or as individual components. According to the catalogue, the range includes:

• Complete core barrels and inner tubes
• Core barrel heads and maintenance kits
• Shelby sampler system for soft soils
• Destructive drilling method system
• Mining overshot and dry hole (inshot) systems
• These options ensure compatibility with a wide variety of drilling techniques and site conditions.

Efficient and Proven Performance

All Geotech S wireline core barrels are manufactured to meet principal international standards. This ensures easy integration with existing drilling equipment and rods. It also supports global use across different drilling markets.

The Geotech S wireline core barrels combine durability, precision, and ease of use. Their design supports smooth operation, reduced wear, and reliable core recovery over long drilling campaigns.

To see the Geotech S in operation, you can watch the drilling demonstration video available online. It clearly shows how the system works in real drilling conditions.

A Complete Wireline Core Barrel Range

In addition to the Geotech S, our wireline core barrels range includes TCS 146, B-WL, N-WL, H-WL, P-WL, and HDC. These systems can be supplied complete, partly assembled, or with dedicated accessories, depending on project requirements.
