GeoSpec core analyzers provide cutting edge solutions for the core analyst.
The GeoSpec range of instruments is the result of a successful long-term collaboration between Oxford Instruments and Green Imaging Technologies (GIT), the world leaders in hardware and software for NMR core analysis. First introduced in the mid-1990s, the GeoSpec now has well over 100 installations worldwide in oil companies, service companies and academia.
The GeoSpec includes instruments from 2MHz to 23MHz operating frequency, handling samples from ½ to 6 inches diameter, with integrated software and accessories to suit all users from routine core analysis to advanced petrophysics research.
Entry level GeoSpec systems come complete with LithoMetrix™ software which carries out routine measurements such as T1 and T2 -based pore size distributions, porosity, and fluid mobility measurements such as Free Fluid Index (FFI), Bound Volume Irreducible (BVI) and Clay Bound Water (CBW).
Higher performance hardware incorporating pulsed field gradients is matched with greater software capabilities of the GIT Systems software including measurement of hydrogen index, diffusion, and fluid typing by 2-D data mapping.
Top of the range GeoSpec systems include saturation profiles, spatially-resolved T2 distributions, and GIT’s patented capillary pressure (Pc) measurement package, GIT-CAP™. GIT-CAP allows users to obtain Pc measurements 5 times faster, while getting up to 10 times as many data points per scan, compared to traditional measurement techniques.
With the optional P5 Cell for overburden studies, users can perform analysis on 1” and 1.5” diameter samples at up to 5,000 psi of pressure and at temperatures to 100°C. All GeoSpec systems include Oxford Instruments’ revolutionary Q-Sense signal enhancement technology, which provides industry-leading short echo spacings (essential for measurements on tight rocks and shales, which have a high proportion of small pores) while maintaining high signal to noise ratios (SNR). This unique combination allows measurements to be made up to four times faster, with echo spacings several times shorter, than in previous instruments. Q-Sense also allows successive measurements to be made on cores of varying salinity, without the need to retune the probe between samples.
