GIT’s 2D NMR maps provide petrophysicists and reservoir engineers information about the fluids within the reservoir and the pore connectivity of the rock.

This information allows for better extraction plans. The NMR measurements are well suited to unconventional reservoirs such as shales, providing information that cannot be found any other way.

2D NMR mapping studies can be performed on samples using temperature to allow quantification of bitumen which too can assist technical experts in their understanding of their reservoirs.

GIT Systems Basic software allows users to perform the patent protected GIT 2D NMR map measurements on a gradient enhanced GeoSpec NMR instrument. Various field strengths can be used although using a higher field strength will speed up the measurement.

More information on T₁and T₂correlation maps for fluid typing and bitumen quantification can be found in this application note.

The enhanced signal-to-noise ratios (SNR) and shorter TAU values available from modern NMR core analyzers, such as the GeoSpec, allow users to measure more data rich measurements such as 2D correlation maps.

In the past, extremely long acquisition times for T₁– T₂maps, or correlation plots, made them next to impossible to obtain. Current SNR levels have eliminated this limitation and have allowed researchers to begin exploring what can be learned from these maps. Some examples of such measurements include spatially resolved T₂, diffusion studies, and 2D correlation maps, or simply 2D NMR maps.
