Abstract:
A method may comprise disposing a nuclear magnetic resonance logging tool into a wellbore, identifying an upper limit of an amplitude for tool motion, identifying a frequency range based at least in part on the upper limit of the amplitude for tool motion, measuring the one or more frequencies from the echo train, and performing a frequency-domain processing of the one or more frequencies to suppress distortions in an echo train. A system may comprise a nuclear magnetic resonance logging tool and an information handling system. The nuclear magnetic resonance logging tool may further comprise an electromagnetic transmitter configured to emit a magnetic field, a radio frequency transmitter configured to transmit a pulse and one or more refocusing pulses, and a receiver configured to detect one or more frequencies from an echo train.
