Abstract: Irreducible water saturation (Swir) and bulk irreducible fluid volume (BVI) from neclear megnetic resounace logging are not directly measured quantities but are derived from theT2 distribution and the effective porosity. Thus, the acurracy of SwirandBVIis dependent on the methods and associated pa-rameters used in the interpretation of theT2distribution data.The methods used in NMR logging include theT2cut-off value,T2spectraBVIandBVIweighting function.
Key words: neclear magnetic resounace, irreducible water saturation, frequency spectrumBVI, weighting function
