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.

本数据集收录了三种岩石样本的1H核磁共振自感应衰减数据：（a）贝雷砂岩，（b）克拉卡油田的丹尼亚石灰岩，以及（c）丹油田的丹尼亚石灰岩。所有岩石均浸泡于2 wt%的NaCl溶液中，并通过两种仪器进行测量：（1）牛津Maran DRX-HF垂直孔永久磁体，频率为8.5 MHz，（2）配备Tecmag控制台的水平孔2.4 T超导磁体，频率为98.8 MHz。
