We propose a new method to determine wettability indices from NMR relaxometry. The new method uses the sensitivity of low field NMR relaxometry to the fluid distribution in oil-water saturated porous… (More)
The study reported here presents the analysis of raw NMR log data performed in a bitumen sand deposit zone and the comparison with NMR laboratory experiments performed on plugs and processed with the… (More)
We present NMR relaxation experiments of water and oil confined in a series of calibrated porous media and natural rocks of different wettability, at various temperatures and magnetic fields. The… (More)
Abstract Low field nuclear relaxation measurements applied to porous media can provide a wide variety of information. One important use of NMR measurements in the petroleum industry is the estimation… (More)
