29 SEPTEMBER 2023 WorldWide Drilling Resource® Introducing the S Geobor Wireline HPD System from TerraRoc: A Revolution in the Deployment of HPD Equipment Adapted from Information by Azzurro-Blu TerraRoc, a global leader in geotechnical drilling solutions, in collaboration with SOCOTEC UK Ltd and HPD (high pressure dilatometer) manufacturer Cambridge Insitu Ltd, was thrilled to announce the launch of the innovative S Geobor Wireline HPD System. “This breakthrough is more than just a technological innovation. It's a game-changer that will transform the way our customers approach core drilling projects. The S Geobor Wireline HPD System not only enhances operational efficiency but also delivers comprehensive, high-resolution data that our clients can trust," said Deyvi Akkris, business line manager, Europe and LATAM at TerraRoc. Developed with a strong focus on enhancing productivity, this cutting-edge system significantly reduces manual handling and deployment time, providing geotechnical engineers and drill operators with a tool which dramatically improves project efficiency. At the heart of the S Geobor Wireline HPD System is the HPD, an instrumented downhole pressure meter providing unparalleled measurements of rock formation properties under different loading conditions. “Our collaboration with TerraRoc and SOCOTEC has resulted in a product that leverages the best of our collective expertise. The wireline HPD system is a much-needed innovation to streamline the use of our HPD with the industry-leading S Geobor Wireline Coring System, and we are proud to have contributed to its creation,” said Simon Baxter, managing director at Cambridge Insitu Ltd.” Featuring a cylindrical, flexible membrane which expands under pressure, and downhole strain gauged transducers for displacement and pressure measurement, the HPD delivers real-time, high-resolution data on the deformation and stress of rock formations under loading. The state-of-the-art system eradicates the need for drill rods, instead deploying the HPD into the borehole via a wireline. Positioned at the desired depth using the S Geobor drill string, the probe expands under pneumatic pressure, delivering realtime measurements with unprecedented accuracy. This accurate data aids decision making by providing comprehensive insights into rock formation properties including stiffness, strength, and in situ stress, all critical parameters in designing secure and efficient structures. The S Geobor Wireline HPD System offers users: • Significant reduction in manual han- dling • Increased productivity with real- time data transmission • Precise measurements of rock for- mation behavior under loading • High-resolution data acquisition using transducers inside the probe • Comprehensive analysis of rock for- mation under different loading con- ditions The S Geobor Wireline HPD System is a complementary addition to TerraRoc’s Terracore drilling system, extending the potential for efficient and effective in situ data acquisition during site investigations.
