Samples:
To test the RARE and ZTE pulse sequences in porous media, various NMR
samples were prepared. All samples were loaded in 15 mL Falcon tubes
with the dimensions of O.D. 17 mm and length of 120 mm. These tubes were
used to reduce the evaporation or loss of water saturation during NMR
data collection.
All core plugs were saturated with demineralized water by placing the
sample in a vacuum cell for 24 hrs. Sample 1 : 20.866g of 4.0 mm
glass beads immersed in 8.0 ml of water. The sample dimensions for the
rock cores core are described in Table 1.
