Method for generating synthetic T1-T2 maps from marginal distributions of nuclear magnetic resonance logging tools

Abstract

The present invention falls within the area of well logging to evaluate formations in oil and gas producing fields. Particularly, the present invention describes a method for generating synthetic T1-T2 maps from marginal distributions of nuclear magnetic resonance logging tools, wherein the method comprises: decomposing marginal distributions of T1 and T2 relaxation times into an initial sum of log-normal functions with the same amplitudes and different means and standard deviations; setting the initial amplitudes, means and standard deviations so that the sum of log-normal functions corresponds to the marginal distributions of T1 and T2; and using the amplitudes, means and standard deviations set in a sum of two-dimensional log-normal functions to generate a synthetic T1-T2 map.
