Abstract
A packer includes a seal element and a piston. The piston compresses the seal element to form an annular seal in the well. A pressure wave, such as a pressure wave that is caused by a chemical reaction or the detonation of an explosive, is generated in the packer to at least partially assist an operation (the setting of a slip, setting of the seal element, etc.) of the packer. In some implementations, the chemical reaction or explosive detonation occurs in response to a predetermined movement of the piston.
