GeoSpec is the industry standard NMR core analyser, with installations in almost every major oil producer and SCAL laboratory world-wide.

Our partnership with Green Imaging Technologies guarantees complete hardware and software integration which makes it possible for any core analysis laboratory to obtain comprehensive NMR core analysis results without the need for an in-house NMR expert.

GeoSpec models for routine measurements of relaxation distributions generally operate at 2MHz in order to reduce artefacts caused by ferromagnetic material in the samples and to mimic the operation of the NMR logging tools. Higher field versions are also available for special applications such as Magnetic Resonance Imaging (MRI). Standard GeoSpec instruments are available in three different magnet sizes to accommodate cores of different diameter from 1” up to full core.

All GeoSpec2 models are equipped with Q-Sense, our ground-breaking new technology for improved signal-to-noise and ultra-short echo times.

Both features essential for accurate measurements on tight rocks and shales.

With the addition of extra hardware and software options, the GeoSpec range is also capable of more advanced research applications, some of which are described below.

Research Applications

By adding an accessory called Pulsed Field Gradients (pfg) to the NMR instrument, it becomes possible to carry out measurements dependent on the diffusion, flow, or distribution of the fluids within the core sample. This allows us to conduct measurements to investigate, for example, fluid typing and fluid distribution.

Patented software allows 2-dimensional data maps to be constructed to help with fluid typing, and other patented software generates spatially-dependent T2 distributions from “slices” along the core length.

For users who are familiar with NMR and wish to add their own measurement protocols to the standard software, an Application Developer package is available. This allows users to write their own NMR pulse sequences and make the protocols available to other users through the standard software interface.
