Robertson runs one of the largest geological, environmental and machine condition monitoring laboratories in the world.
Established at the inception of Robertson Research in 1961, the laboratories now boast a complete range of diagnostic and interpretive services that range from upstream petroleum services through to environmental testing and the "Wearcheck" oil condition monitoring and predictive maintenance programmes.
In addition, included in this section of the web site, are the details concerning Robertson's extensive core handling, core storage and core laboratory services.
Research and Development
Robertson recognises the need for maintaining innovative research and development programmes to ensure core analysis keeps abreast of changing technology and requirements.
Evaluation analysis of freezing unconsolidated cores
Robertson has carried out extensive research into the effects of freezing (at various rates etc.) on unconsolidated core. This industry funded research programme has become a major contribution to the current handling and analysis practices for unconsolidated and friable core. Through this research and extensive experience Robertson has become the industry recognised leader in unconsolidated core analysis.
Resistivity index of shaly sands at low brine saturation
The main objective of this project which was completed in the first part of 1998 was to measure electrical properties down to the lowest brine saturations achievable. It is at these low brine saturations that the electrical properties of the clays cause the greatest anomalies in the downhole resistivity logs. Samples with varying clay content and type and brines of different salinities were studied. New techniques and equipment have been developed in conjunction with this research.
Electrical impedance tomography (EIT)
It is widely recognised within the industry that confidence in core analysis data (especially relative permeability measurements and continuous injection resistivity index) is greatly enhanced when the test is performed with the aid of in situ saturation monitoring. However, methods currently available for routine analysis of core samples have severe limitations.
Electrical impedance tomography is becoming increasingly established as the imaging technique of first choice in a range of applications in a variety of disciplines, and the large difference in electrical properties of reservoir fluids used in core analysis make it an ideal tool for saturation monitoring.
Robertson, in conjunction with the University of Aberdeen and the Geological Survey of Denmark and Greenland, is commencing a project aimed at the development of EIT based saturation monitoring equipment.
