Claim 0:
1. A method for enhancing productivity of a stratified subterranean wellbore, the method comprising:
introducing a mixture comprising water and a first set of nanoparticles to a first target zone of the stratified subterranean wellbore, where the first set of nanoparticles is reactive to high frequency acoustic waves and has a size in a range of about 10 to about 100 nm, and where the first target zone is located in a high permeability layer of the stratified subterranean wellbore;
providing a first stimulation to the first set of nanoparticles to promote a reacting of the first set of nanoparticles, where the first stimulation comprises acoustic waves having a frequency range of 1 kHz to about 10 kHz;
introducing water to the first target zone;
introducing a mixture comprising water and a second set of nanoparticles to a second target zone of the stratified subterranean wellbore, where the second set of nanoparticles has a size in a range of about 1 to about 10 nm, and where the second target zone is located in a medium permeability layer of the stratified subterranean wellbore;
providing a second stimulation to the second set of nanoparticles to promote a reacting of the second set of nanoparticles, where the second stimulation comprises acoustic waves having a frequency range of 100 Hz to about 1 kHz; and
introducing water to the second target zone.
