Abstract
Methods and logging systems for performing nuclear magnetic resonance (NMR) logging in downhole operations are described. The methods include performing a scout logging acquisition operation using an NMR logging tool to determine NMR logging parameters of a formation interval, setting an NMR logging acquisition mode based on the NMR logging parameters from the scout logging acquisition operation, and performing an NMR data logging operation to determine properties of the formation interval based on the set NMR logging acquisition mode.
