Abstract

Nuclear magnetic resonance (NMR) is the response of atomic nucleus to external magnetic fields. In this work we have investigated the new method of MRIL, well logging by use of Nuclear magnetic resonance, to determine petrophysics parameters, such as porosity and pore size distribution to estimate hydrocarbon in the reservoir. Using the NMR data, we have calculated porosity and then compaired it with the neutron porosity. The results show good agreement between NMR porosity and the core porosity, but the neutron porosity is more than the core value
