Title: Detecting tool motion effects on spin echoes obtained with nuclear magnetic resonance measurements

Abstract: An NMR measurement obtained with a logging tool is potentially subject to relative motion between the apparatus and a sample. An echo train is produced having a plurality of spin echo signals. At least two of the spin echo signals are analyzed to determine a effect of tool motion on the NMR measurement.
