About Us
For over 40 years Robertson Geo has pioneered the development of wireline logging instrumentation technologies and techniques.

The comprehensive range of geophysical logging solutions and software is developed and built at its North Wales manufacturing and calibration centre. On-site test facilities include a 100m test borehole, calibration blocks, ovens and autoclaves capable of testing complete probe assemblies in "real world" conditions, providing a full suite of traceable calibration and quality assurance data.

From the Arctic to Australia, from coal mines to windfarms, energy developments to sky-reaching superstructures, Robertson Geo technologies have been used to acquire quality geophysical data from over 160 countries around the globe. As an end user of its own products, the Robertson Geo engineering feedback loop from direct field experience fosters a continuous improvement culture driven by own use, leading to mature systems that are truly "industry hardened" innovative products.

Robertson Geo believes safety and quality assurance to be of prime importance in executing an efficient and safety-focused approach to field investigations, and the satisfaction of client requirements. You can be sure that Robertson Geo technologies are easy to work with, validated and ready to go. All sales and service activities are reinforced by focussed development engineering and manufacturing teams to provide comprehensive technical support and the reassurance only an OEM can offer.

Highly trained field engineers are available to be deployed for borehole logging services to any location worldwide. Downhole probes and surface equipment is offered for purchase, lease to buy (GeoKey®) or rental offering a range of flexible options for any project requiring calibrated wireline logging data of proven quality and reliability.

Robertson Geo's High Resolution Optical Televiewer (Hi-OPTV) provides a continuous very high resolution oriented image of the borehole walls using a conventional light source. A unique optical system based on a fisheye lens allows the probe to survey 360 degrees simultaneously. This information is processed in real time to produce a complete 'unwrapped' ... Moreimage of the borehole oriented to magnetic north. The probe offers superior resolution to the High Resolution Acoustic Televiewer (HRAT) and produces images in real colour. While, unlike the HRAT, it can operate in air-filled boreholes, it is unsuitable for boreholes containing mud or cloudy fluids.

WellCad™ Image-Processing Software
WellCad™ is a Windows-based package for processing, interpreting and displaying acoustic and optical televiewer image logs. Standard log presentations include tadpole and stick plots, stereographic projections of poles to planes and azimuth frequency diagrams. The synthetic core display allows convenient comparison of log and field data for orientation of fractured or incomplete core sections.
Robertson Geo's 3-Arm Caliper probe provides a single continuous log of borehole diameter, as recorded by three mechanically coupled arms in contact with the borehole wall. 710mm, 1000mm and 1500mm range calipers are available to suit a range of well diameters. The caliper is a useful first log to determine the borehole conditions before running more ... Morecostly probes or those containing radioactive sources.

Principle of Measurement
Opening and closing of the motor-drivercaliper arms is by surface command, allowing the probe to run into the borehole with the arms retracted. Once opened, the spring-loaded arms respond to borehole diameter variations as the probe is raised up the borehole.
Robertson Geo's Density Guardlog probe uses dual shielded detectors to provide a borehole compensated density measurement with good bed-boundary resolution, similar to the Formation Density probe. The Density Guardlog probe offers an additional LL3 focussed electrical measurement with good vertical resolution and depth of investigation.... More

Principle of Measurement
The Density Guardlog probe contains a detachable 137Cs gamma source and two scintillation gamma detectors. The active windows of the source and detectors are maintained in contact with the borehole wall by a motorised caliper arm. Gamma radiation back-scattered by the formation (Compton effect) reaches the detectors where the relative count rates provide a measure of formation density.
Case Studies
The project was to investigate the small strain moduli of the sea bed down to 45m using the Robertson Geo PS Logger. The acquired data would then be used to calculate the parameters for constructing the Vesterhav Offshore Wind Farm off the North West coast of Denmark. The geologic formations were typically sands, clays and mudstone.... More

Logging was conducted from the support vessel Freja, which has a compensated drilling platform. The PS Logger provided high resolution, shear wave and compressional velocity data in rock and soils at depths up to 500m, from measurements within a single borehole. Often it proves technically superior and more cost effective than a downhole or cross-hole seismic survey.

Thirteen boreholes were logged over a period of 10 weeks to obtain the P and S wave velocities of the sea bed down to approximately 45m at 1m intervals. These velocities were then applied to the small strain moduli equations with the addition of density, to give Shear, Bulk and Youngs modulus.

The logging probe was successfully deployed with 100% reliability; boreholes were logged from approximately 45m up to the overburden casing. Following logging operations, the operator would quickly process the data acquired. Robertson Geo Engineers were on-board the Freja throughout the project and available for logging through 24 hours each day.
Robertson Geo service engineers are highly trained and fully certified for offshore work. Logging on offshore locations demands versatility of both crews and equipment to get the job done. Here, the 2,000m marine winch has been suspended in the gantry to deploy geophysical probes for offshore subsurface investigation near New Bedford, Massachusetts, ... MoreUSA.

If you look carefully you can just about see the Robertson Geo logging crew behind the marine winch in this image of the set up prior to logging.

Working experience by Robertson Geo offshore logging crews has led to the introduction of the 2,000m marine winch, designed to resist corrosive and saline conditions. Precision engineered for reliable use in the most challenging offshore applications, the marine winch is fully compatible with the Micrologger2 surface data acquisition system and the full range of probes to depths of 2,000m.
The customer required information to assist with constraining parameters for modelling the development and planning of a proposed sea wall and port. This required logging a framework to investigate boreholes in a shallow water tidal area where the proposed sea wall and marine offloading facility would be constructed off the north coast of Anglesey.... More

Borehole depth was 10-80m - a suite of probes was used to identify fractures, fault patterns and ground stability, including Optical Televiewer, High Resolution Acoustic Televiewer, Full Waveform Sonic and Borehole Geometry with inbuilt X and Y calliper. Surface equipment was a 2,000m winch with 3/16” core cable, connected to a Micrologger system.

Logging of 26 holes was successfully completed over a period of two months. The Robertson Geo team supported two jack-up rigs, with Engineers on 24 hours availability over the duration of the project. The jack-up rigs were accessed from a small rib boat that docked at nearby Cemaes Bay.
PDAC: The World's Premier Mineral Exploration & Mining Convention is the leading convention for people, companies and organisations in, or connected with, mineral exploration. In addition to meeting over 1,000 exhibitors, 3,500 investors and 25,600 attendees from 135 countries, you can also attend technical sessions, short courses and networking ... Moreevents. The four-day annual convention held in Toronto, Canada, has grown in size, stature and influence since it began in 1932 and today is the event of choice for the world's mineral industry.
