WebComparing the diffusion and relaxation components of the uptake model of each fluid, it is clear that the main difference between them is the relaxation stage. There is a similar initial uptake for both fluids until the 200-h mark is reached, but with a very different relaxation phenomenon, which results in a much higher final sorption value ... WebFeb 21, 2024 · Nuclear magnetic resonance (NMR) relaxation time provides valuable information about properties of fluid and solid surfaces within rocks; however, the complexity of rock samples makes it difficult to quantify the effect of solid–fluid interactions on NMR measurements. Additionally, the ability of 2 MHz NMR equipment to probe …
