Total porosity from nmr
WebFor NMR research, it is often assumed that the measured sample is fully saturated [e.g. [7] - [11] ], and in this case, A 0 is equal to the total porosity. In like manners, in a saturated … WebComprehensive reservoir evaluation requires determination of irreducible fluids, movable fluids and permeability. Although the NMR petrophysical properties of coals have been studied for decades, the impact of heat on these properties (pore size distribution, pore structures, porosity and permeability) has not yet been systematically investigated.
