Permeability determinations from nuclear magnetic resonance measurements |
摘要 |
Permeability determinations are made from NMR measurements of a logging tool. The NMR measurements are used to find an observed critical spin-spin relaxation time which is used in conjunction with an in situ determination of surface relaxivity of a rock in order to generate permeability determinations.
