From its beginnings in 1979, Robertson Geologging pioneered the development of slim-hole digital borehole logging systems and techniques. Now, as the largest global supplier of slim-hole borehole-logging equipment in the world, RG supplies well-logging instrumentation and contract logging services to every continent.
Industries served include oil and gas, nuclear and civil engineering, geotechnical, water-well management, environmental and mining. Our subsidiary company, Robertson Geologging (USA) Inc., directly supports the North and South American markets while an extensive network of factory-trained local agents and representatives provides support elsewhere.
Robertson Geologging is majority owned by the OYO Corporation of Japan and enjoys the technical and organisational benefits of membership of this major international group. Our headquarters are located in the UK, close to Llandudno in North Wales. The site also contains our design and development department and our main assembly unit. On-site test facilities include a borehole, calibration blocks and ovens and autoclaves capable of testing complete probes at temperatures up to 260degC and pressures up to 100MPa.
