Paper presented at the 2014 SEG Annual Meeting, October 26–31, 2014
Paper Number: SEG-2014-1663
... Summary Nuclear magnetic resonance (NMR) transverse relaxation times (T 2 ) were measured for carbonate rocks saturated with brine and crude oil under different saturation conditions. The NMR measurements were intercalated within the stages of standard wettability core analyses, which monitor...
