Since 1979 Robertson Geologging Ltd has been the pioneer developer of geophysical logging technologies and techniques. We are presently engaged in a programme of technical development and investment to future-proof our products and services. With customers globally referring to us as Robertson Geo we are taking this opportunity to rebrand and to review our marketing approach. Now, as probably the largest global supplier of slim-hole borehole-logging equipment in the world, RG supplies well-logging instrumentation and services to every continent. Industries served include oil and gas, nuclear and civil engineering, geotechnical, water-well management, environmental and mining. Our subsidiary companies, Robertson Geologging (USA) Inc., directly supports the North and South American markets and Robertson Geologging ASIA Ltd supports clients in the Middle East, Indian Sub-Continent, Asia and Australiasia while an extensive network of factory-trained local agents and representatives provides support elsewhere. Robertson Geo 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.
