ABSTRACT:
A device for fracturing a subterranean formation includes a propellant charge which generates, during combustion, a large quantity of high pressure combustion products. A drogue is provided on the device to prevent or minimize rapid upward movement of the device during combustion. This obviates "bird nesting" of the wire line, wire line damage and the like.
