Modified low field NMR method for in-depth pore space analysis and Fe-containing minerals influence mitigation in tight siliciclastic and extrusive rocks

This data set contains T2 relaxation time data of two different Low-Field Nuclear Magnetic resonance (LF-NMR) approaches, standard and modified differential, along with the Mercury Injection Capillary Pressure (MICP) and X-Ray Diffraction (XRD) data.

The modified differential approach employs the subtraction of the dried sample signal from the signal of the 100 % water-saturated sample before taking the Laplace transform, giving a differential distribution devoid of the unwanted signals from rock matrix, closed porosity and clay-bound water. This method skips the background subtraction step characteristic of the standard approach, achieving a higher Signal-to-noise ratio.
