Estimering av permabilitet

摘要

A permeability estimation technique for use with spin echo signals that are received from a sample includes summing indications of the amplitudes of the spin echo signals. The results of the summing are used to determine an indication of a permeability of the sample, without using a distribution of relaxation times in the determination. The products of indications of the amplitudes of the spin echo signals may be summed, and the results of the summing may be used to determine an indication of a permeability of the sample, without using a distribution of relaxation times in the determination.
