Abstract

A method for enhancing productivity of a stratified subterranean wellbore includes introducing a mixture including water and a first set of nanoparticles reactive to high frequency acoustic waves having a size ranging from about 10 to 100 nm to a first target zone, located in a high permeability layer of the stratified subterranean wellbore. A first stimulation including acoustic waves having a frequency range of 1 kHz to 10 kHz is provided to the first set of nanoparticles to promote reacting. Then, a mixture including water and a second set of nanoparticles having a size ranging from about 1 to 10 nm is introduced to a second target zone, located in a medium permeability layer of the stratified subterranean wellbore. A second stimulation including acoustic waves having a frequency range of 100 Hz to 1 kHz is provided to the second set of nanoparticles to promote reacting.
