Fluids can be determined on samples directly using NMR technique [1 ,2,3]. The amplitude of the NMR signal is
related to the number of hydrogen protons, the technique can be used in geophysics to measure the water contem
of rocks and soils [ 4,5]. In this study, to identify relaxation times according to porosity values we used synthetic
samples. For the NMR measurements, we used monomodal glass pearl samples (0, 1-0,5-0,8-1 ının) and san d
samples (0,35-0,75-1,5 mm) with additional water or petroleum. According to the relaxation times we measured
porosity and compare them with ordinary Iab measurement results. For the results T 1 (JNVREC) and T2(CPMG)
relaxation tin1es are ınuch better suited than T2*(FID) for the analysis. All n1easuren1ents were carried out in the
departn1ent of Geoscience, Technical University of Berlin in Gennany.
