AI Article Synopsis
- Researchers conducted a study on tridecane quartz sand using various NMR techniques to analyze its porous structure and fluid distribution.
- They utilized three specific NMR methods: pulse field gradient NMR, DDif experiments, and tau-scanning experiments, highlighting the benefits of each approach.
- The first two techniques provide insights into the sizes and geometry of the pores, while the tau-scanning method reveals details about the internal magnetic field gradients and the localization of fluids within the porous media.
Article Abstract
Fully and partially filled with tridecane quartz sand was studied by different NMR techniques. The set of NMR experiments was carried out to obtain information about porous media geometry and fluid localization in it in case of partially filled porous space. The study was done using three NMR approaches: pulse field gradient NMR (PFG NMR), DDif experiment and tau-scanning experiment. The possibility to use all three approaches to study porous media properties even at the high resonance frequency is shown together with complementarity of the given by them information. Thus, first two approaches give information about porous sizes and geometry, at the same time tau-scanning experiment allows us to obtain information about distribution of internal magnetic field gradients in the porous space and draw conclusions about fluid localization in it.
