More than 60 years ago Archie said “If it were possible to measure the fundamental properties (exact pore size and fluid distribution) in situ of formations penetrated by the bore hole, the volume of the hydrocarbon in place and the productivity of the could be calculated. However, it is practically impossible as yet to get a direct measurement of the factor, porosity, permeability, hydrocarbon saturation, and thickness of the layer in place by coring or other physical measurements”.
Modern NMR makes Archie’s dream possible both as a laboratory and downhole measurement. Interestingly, the results are “non-Archie”, which means NMR provides a measure of rock properties independent of other techniques.
An independent realisation of rock properties, for comparison with conventional sources, either validates results or shows where discrepancies occur. In both cases, NMR provides a tool for recognising and/or reducing uncertainty. Clearly, NMR data completes the formation evaluation story; without the independent benchmark the story is too often incomplete.
NMR also bridges disciplines because it provides the geometrical configuration of the pore system to link with sedimentological, petrophysical and engineering information. Consequently, NMR provides answers for an independent, single-well interpretation, and a foundation for predicting rock properties into the geological model.
