Patent ID: 8547093

Claim:
A method which corrects nuclear magnetic resonance (NMR) logging data comprising the steps of: acquiring a set of echo data comprising a plurality of echo points using an NMR logging tool; applying a multiplicative correction factor to the acquired echo data comprising a plurality of echo points using a multiplicative operation in order to obtain a corrected fit; determining a fit of the echo data, wherein the fit of the echo data is determined by performing a single value decomposition (SVD) on the echo data; applying a speed correction factor to the fit of echo data using a multiplicative operation in order to obtain a corrected fit; determining a difference between the fit and the corrected fit; and applying additively the difference between the fit and the corrected fit to the echo data in order to yield additively-corrected echo data; wherein the speed correction factor is determined as that which brings the response of the NMR logging tool while moving within a resonant region to that of the NMR logging tool while stationary.
