Magnetic Resonance Free Induction Decay of Geological Porous Materials in the Single-Exponential and Non-Exponential Regimes

This dataset contains ¹H magnetic resonance free induction decay of three rock samples: (a) Berea sandstone, (b) Danian chalk from the Kraka oilfield, and (c) Danian chalk from the Dan oilfield. All rocks are saturated with 2 wt% NaCl solutions and were measured by two instruments: (1) Oxford Maran DRX-HF vertical bore permanent magnet at ¹H frequency of 8.5 MHz, and (b) Nalorac 2.4 T horizontal bore superconducting magnet equipped with a Tecmag console at ¹H frequency of 98.8 MHz.
