abstract = {A lightweight Halbach magnet system for use in nuclear
magnetic resonance (NMR) studies on drill cores was designed
and built. It features an improved homogeneous magnetic
field with a strength of 0.22 T and a maximum accessible
sensitive volume. Additionally, it is furnished with a
sliding table for automatic scans of cylindrical samples.
This device is optimized for nondestructive online
measurements of porosity and pore size distributions of
water-saturated full cylindrical and split semicylindrical
drill cores of different diameters. The porosity of core
plugs with diameters from 20 to 80 mm can be measured
routinely using exchangeable radiofrequency coils. Advanced
NMR techniques that provide 2D T(1)-T(2) correlations with
an average measurement time of 30 min and permeability
estimates can be performed with a special insert suitable
for small core plugs with diameter and length of 20 mm.},
