Patent ID: 8614573

Claim:
A method to determine a subsurface formation property of an earth formation, comprising: disposing a logging tool in a wellbore that penetrates the formation; using the logging tool to measure signals corresponding to one or more measurement types, the one or more measurement types including at least multiple passes of nuclear magnetic resonance (NMR) measurement data measured at each of a plurality of depths of investigation, wherein the measured signals have an initial signal-to-noise ratio; using a processor to: increase the signal-to-noise ratio of the measured signals by laterally stacking the multiple passes of the NMR measurement data to obtain the laterally stacked NMR measurement data having a higher signal-to-noise ratio than the initial signal-to-noise ratio, performing a fluid volume analysis of the formation based upon the increased signal-to-noise ratio signals, determining the subsurface formation property based upon the fluid volume analysis, and providing the determined surface formation property to a user.
