NMR Software Solutions
for the future
The world’s cutting-edge rock core measurement techniques
are all available in software solutions provided by Green
Imaging Technologies (GIT) and the GeoSpec line of NMR
analysers developed by Oxford Instruments.
The GIT Systems software line of products provides fast, accurate, non-destructive analysis of core plugs andis a proven asset in reservoir characterization. Reservoir properties such as capillary pressure, porosity, boundwater, wettability, and relative permeability can all be measured or modeled from rapidly acquired NMR data. GIT’ssoftware solutions solve current laboratory limitations and bring a new standard of simplicity, clarity, and usability.
The elegant user interface makes the acquisition, manipulation, and reporting of data exceptionally simple. We
specialize in tight rocks, shales and other difficult regimes. From exploratory wildcats to increasingly difficult EOR
regimes, GIT’s powerful techniques will help maximize core’s data potential.
From Prediction to Production, GIT’s software solutions and laboratory measurement techniques lead the way.

Software that works for you
All GeoSpec rock core analysers come completewith LithoMetrix software, which acts as
the user interface and performs all instrument
management and basic core analysis functions.
LithoMetrix can be upgraded to a version
of GIT Systems software for more advanced
measurements. GIT Systems packages include
GIT Systems Basic, GIT Systems Advanced andGIT Systems 3D Imaging. Each user can selectthe software package that includes the tests theywant to perform on theirGeoSpec instrument.

All software packages include:• Intuitive user interface, designed in collaboration
with professional rock core analysts.

• Diagnostic aids, easy calibration tools, andinstrument performance database.

• Routine measurements pre-packaged withautomatic calculations.

• Project and sample results database maintained
automatically.

• “Scan cards” allow multiple measurements tobe set up in advance, to run unattended.

• Software used, tested and continually improved in
our own commercial core laboratory.

GIT software solutions maximize the power of theGeoSpec NMR instrument by expanding the analysis
that can be performed; accurately and repeatably.

LithoMetrix™
Our most basic software package, LithoMetrix acts as theoperating system for the NMR instrument, simplifying calibrationand maintenance of the system while providing a simple interface
for users to perform the basic NMR analysis functions.
Process your data:• Reprocessing of 1D Inversions• Exponential fitting of Data
• Standard permeability models (Coates & T log mean)• Compute model coefficients or2

GIT Systems Basic
GIT Systems Basic adds to themeasurement capabilities within
LithoMetrix. We recommend thatany GeoSpec analyser with gradientsbe equipped with GIT Systems Basic
software so the power of the gradientscan be harnessed for more complicatedmeasurements such as diffusion.
