Abstract :
In this paper we describe a new approach for the estimation of the porosity and its uncertainty from Nuclear Magnetic Resonance relaxation measurements in porous media. The new approach is based on the Fourier transform of the measured data in √t domain. This approach was found to work reasonably well and had a smaller bias and variance in comparison to traditional methods of computing the porosity.
