Abstract
A method of acidizing a geological formation and a method of determining an effectiveness of the acidizing with NMR spectroscopy. Variations of acidizing and determining the effectiveness of the acidizing are described. The method includes recording a first nuclear magnetic resonance spectrum of a geological formation, calculating an interconnectivity number, acidizing the geological formation, again recording an NMR spectrum and calculating an interconnectivity number to compare the interconnectivity before and after acidizing.
