By adding an accessory called Pulsed Field Gradients (pfg) to the NMR instrument, it becomes possible to carry out measurements dependent on the diffusion, flow, or distribution of the fluids within the core sample. This allows us to conduct measurements to investigate, for example, fluid typing and fluid distribution.
Patented software allows 2-dimensional data maps to be constructed to help with fluid typing, and other patented software generates spatially-dependent T2 distributions from “slices” along the core length.
For users who are familiar with NMR and wish to add their own measurement protocols to the standard software, an Application Developer package is available. This allows users to write their own NMR pulse sequences and make the protocols available to other users through the standard software interface.
