NMR studies of core samples of different disintegration degrees were carried out to determine their reservoir properties depending on the degree of size reduction. It was established that the results do not depend on the particle size of the measured sample and are consistent with the results of standard petrophysical studies performed on core samples. It is shown that the data operatively obtained on the drill cuttings by the NMR method can be used as initial information in interpreting production well logging before conducting detailed petrophysical core studies. The results of studying drill cuttings allow to obtain reservoir properties of productive layers even at intervals without core sampling.
