NMR Core Analysers

NMR core analysis has become commonplace with installation in almost every major oil producer and SCAL laboratory world-wide. Low field NMR is routinely used in core analysis laboratories to examine the T2 relaxation time distribution of fluids in core plugs. This information can be interpreted to give information on: pore size distributions; permeability; total and effective porosity; free fluid index and bound water volumes. Measurements of cores in the laboratory on this instrument can be used to calibrate down-hole NMR well logs (e.g. T2 cutoff values). At the FSRD there are two NMR core analysers (below). Both feature core holders able to make measurements at reservoir conditions. Measurements are performed for both oil and gas reservoirs as well as for various mining applications.
