Paper presented at the SPE Annual Technical Conference and Exhibition, September 24–27, 2006
Paper Number: SPE-102435-MS
... Abstract We use nuclear magnetic resonance (NMR) logging to help with the petrophysical evaluation of thin sand-shale laminations. NMR helps to 1) detect thin beds, 2) determine fluid type, and if hydrocarbon is present, 3) establish the hydrocarbon type and volume, and finally 4) determine...

..., including pore isolation and fast diffusion. These assumptions establish the quantitative link between NMR response and petrophysical predictions. While there is a need to test these assumptions directly, to date no quantitative study on reservoir core material has been under taken. The ability to digitally...
