Abstract

Nuclear Magnetic Resonance Imaging has emerged as the leading technological break-through which is providing difficult-to-interpret zones with the astounding results. Formation evaluation aims at finding out fluid saturations in varying geological formations making use of Resistivity, Porosities (Density, Neutron and Sonic), Clay indicators (GR, SP, Rhob, PhiN, Rt, DT, etc), and mineralogical identifiers (spectro metric tools). In spite of acquiring all the information, it is not possible to evaluate the accurate saturations in many cases and in some cases even the qualitative evaluation of saturations due to inherent ambiguities.
