Abstract
An embodiment of a method of performing a nuclear magnetic resonance (NMR) measurement includes disposing a NMR measurement device in a carrier in an earth formation, applying a static magnetic field into a formation, and emitting a plurality of pulse sequences into the formation, the plurality of pulse sequences including at least a first pulse sequence having a first wait time and a second pulse sequence having a second wait time. The method also includes receiving a long wait-time echo train based on the first pulse sequence and a short wait-time echo train based on the second pulse sequence. The method further includes transforming, by a processor, the echo trains into volumetric portions including a first fluid volumetric portion, estimating a longitudinal relaxation time for the first fluid volumetric portion; and identifying whether the first fluid volumetric portion is gas or light oil based on the estimated longitudinal relaxation time.
