The signal to noise ratio (SNR) of the latest generation of lab based NMR core analyzer technology, such as the GeoSpec product line, has been greatly improved. This improvement has opened new options for users looking to perform data rich NMR experiments. Some examples of such measurements include spatially resolved T2, diffusion studies, and 2D correlation maps, or simply 2D maps.
These maps currently are done in 3 versions;
- T1– T2 maps – used to give an indication of the fluid viscosity, fluid type and location of the fluid in the pore network.
- T2-Diffusion – used to separate oil and water and locate it in the pore structure.
- T2-Store-T – used to give an indication of the pore connectivity.
