... and consequently complications in the NMR interpretation. We observed two key issues: porosity deficit due to lack of polarization and T 2 distribution truncation due to the low number of echoes. We used a single pore model to reproduce the NMR response in different pore sizes and fluid types for different pulse...

... permeability and oil content, in two wells of the same field. The anomalous responses are as follows: 1) systematic deficit (10 p.u. on the average) in the apparent Nh4R porosity in comparison to the porosity indicated by the density and neutron logs; 2) distribution of T2 showing high ratio between the volume...
