Green ImagingTechnologies’ GIT Systems software is a powerful SCAL solution.This unique software suite uses Nuclear Magnetic Resonance (NMR) to obtain bothstandard and specialized reservoir measurements. Its advanced capabilities areunderpinned by a robust, user-friendly platform that streamlines every aspect of NMRdata acquisition, processing and reporting. With an emphasis on clarity, simplicity andusability, it maximizes a core’s data potential.

BASE SOFTWAREGIT Systems software is run on an intuitiveplatform that greatly simplifies the acquisition ofNMR measurements in the lab. It provides directhardware control and diagnostics for a variety ofNMR instruments and field strengths whilemaintaining system accuracy through automatedcalibrations. BothT1 andT2 data can be acquiredand automatically processed to give FFI, BVI, CBW,effective porosity, andT1 andT2 cut-offs. Featuresinclude advanced help, imperial or SI unit displayand entry, file import (ASCII and RIDAT formats),and database backup and restore.

GIT-CAP™The patented GIT-CAP capillary pressuremeasurement is directly determined using theknown centrifugal force and the NMR-measuredwater saturation. GIT-CAP is available for bothair/brine and oil/brine systems. The GIT-CAPmodule for oil/brine is unique in that it providesboth the positive and negative portions of thecurves, giving primary drainage, secondary drainage,and imbibition. GIT-CAP has been proven to beaccurate within 2% of conventional measurementtechniques and needs only one or two centrifugeequilibrium speeds to measure the completecapillary pressure curve – more than 5 times fasterthan conventional centrifuge techniques.

FEATURESData generated by the GIT-CAP technique can be used extensively to model such reservoirparameters as NMR permeability, wettability, and relative permeability. One of the most excitingfeatures is QUICK-CAP™, which determines the complete capillary pressure curve using asingle equilibrium centrifuge speed. All features are easily accessed and calculated using theintuitive user interface.

LITHOLOGIESGIT Systems has beenproven effective inmultiple lithologies,and excels in lowpermeability situations.

T1 andT2Routine rock core measurements, includingT1 andT2 distributions, can easily bemeasured using GIT Systems. The FFI, BVI,CBW, effective porosity, T1andT2 cut-offsare automatically computed. Log calibrationand interpretation are improved by usingthese more accurate values.

RELATIVE PERMEABILITYThe correct modeling of reservoir fluidflow is crucial to achieving productionsuccess; yet obtaining reliable relativepermeability data can be difficult andexpensive. Further, this data is often usedto model capillary pressure curves. GITSytems’ relative permeability measurementreverses this procedure and providesdetailed relative permeability data quicklyfrom NMR capillary pressure curves.

WETTABILITYWettability affects many important reservoir characteristics, includingrelative permeability, electrical properties, NMR properties andsaturation profiles, which can all have a critical impact on productionplanning. GIT Systems allows wettability to be modeled from thecapillary pressure results, using the AMOTT or USBM indices.

POROSITY PROFILEGIT Systems uses the NMR instrument to“see” fluids inside the core plug. By directlymeasuring these fluids, the software cancalculate a porosity profile of the plug. Thisis in contrast to a traditional bulk porositymeasurement, which may mask small-scaleheterogeneity in the rock.
