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.
