|Title:||METHODS AND APPARATUSES FOR ECHO PROCESSING OF NUCLEAR MAGNETIC RESONANCE (NMR) DATA|
In one aspect, a nuclear magnetic resonance (NMR) system includes a transmitter of an NMR tool to output a magnetic field pulse into a zone of interest, a receiver of the NMR tool to output an NMR echo data set produced from an interaction of the magnetic field pulse and the zone of interest, and an NMR echo processing module including a filter matched to a response of the NMR tool to output a filtered NMR echo data set from the NMR echo data set. In another aspect, a method of processing an NMR echo data set includes providing from an NMR tool the NMR echo data set produced from an interaction of a magnetic field pulse and a zone of interest, matching a filter to a response of the NMR tool, and filtering the NMR echo data set with the filter to produce a filtered NMR echo data set.
