The Magnetic Resonance Imaging (MRI) log and the Nuclear magnetic resonance (NMR) are resourceful in addressing various scientific questions in petroleum geology, and they have been universally utilized in estimating total porosity due to its repeatability. Notwithstanding, the field applicability of NMR in lieu of MRI logs to estimate total porosity, have not been fully explored. The objective of our study is to develop a novel correlation between the NMR core analyses performed in the laboratory and the field MRI logs. In this study, firstly, we examined various core samples using 2MHz Geospec NMR core analyzer, and our results are compared to results from magnetic resonance imaging (MRI) log taken at 1MHz. Secondly, we performed a detailed analysis of the MRI logs, and NMR core analysis of Bakken Formation. We then evaluated the petrophysical properties of the investigated cores including its porosity, water saturation, and permeability. Our results show that there is a reasonable degree of concordance between the compared investigated results. The results from our study provided a more efficient correlation between MRI log and NMR core by considering the differences in sample volume and difference in frequency.
