The application of nuclear-magnetic-resonance (NMR) logs in low- to moderate-quality gas reservoirs is challenging. The difficulty results from the low NMR gas signature caused by the combined effect of low porosity and a low hydrogen index. If properly used, NMR tools confirm the interpretation by conventional tools and improve on permeability and fluid estimation. Some logging jobs could have provided more information with better planning (of acquisition parameters, tools and mud systems) and more experience. Porosity and permeability by NMR are less dependent on core calibration than conventional derivation from porosity tools. An in-house interpretation increased accuracy and insight into the reservoir.
