Microenergetic particles can be employed in hydraulic fracturing of oil or gas wells. By exciting the microenergetic particles, an operator performing a fracture job can better map the fracture process and/or increase the extent of fracturing over what can be accomplished using only pumps. By deploying microenergetic particles during the fracturing of an oil or gas well, but not exciting the microenergetic particles until there is a reduction of production, an operator can extend the time periods between well stimulations.
