Depending on the age and model of your NMR analyzer, one or more of the following upgrades may be available:

P5 cell – available for all GeoSpec models.P5 cell

Available for all GeoSpec models and some MARAN models. Allows 1” or 1.5” core samples, up to 5000psi and 100ºC (depending on model).

The P5 cell is easily top loaded into the instrument, and can maintain the pressure with the cell both inside and outside the instrument using the included bench top stand. This means that the instrument can quickly go from measuring pressurized samples to measuring ambient samples, while eliminating pressure cycling of the samples. Unlike other overburden cells, the unique design of the P5 cell results in minimal reduction in analyzer performance.

 

Reduced echo spacing (upgrade for GeoSpec 12MHz).Reduced echo spacing (upgrade for GeoSpec 12MHz)

Reduced echo spacings allow the inversion algorithm used to calculate T2 distributions to extract shorter T2 values, leading to more accurate calculation of total porosity. This upgrade adds a cooling facility to the probe to permit higher duty cycles and therefore shorter echo times. The diagram on the left shows T2 distributions from the same sample, with progressively shorter echo spacings from blue, to red, to green. The total porosity calculated from the integral of the green trace is almost four times that from the blue trace.

 

Various software upgrades are available, depending on what software you currently us on your GeoSpec.Various software upgrades are available, depending on what software you currently use on your instrument

Users of older Oxford Instruments rock core analyzers, with only the basic RI-NMR software can benefit by installing LithoMetrix, provided by GIT Imaging Technologies. Since 2011, all Oxford Instruments rock core analyzers have been supplied as standard with LithoMetrix, which provides a more user-friendly interface to control the instrument and automate most of the routine calculations of petrophysical parameters.

Users who already use LithoMetrix or GIT Systems may benefit from upgrading to the latest version of the software, or from upgrading to a more robust software package. The GIT Systems software product line offers advanced measurements such as 2D maps, spatially resolved T2 distributions, saturation profiles and capillary pressure measurements.
