Abstract
A gas generating type fracturing tool is designed to work on long productive intervals and includes a series of separate propellant charges, an igniter for initiating combustion of one of the charges and means for transferring combustion from one charge to the next. In one embodiment, combustion of the charges occurs one after another with little or no delay between successive charges. In other embodiments, a delay is incorporated in the combustion train between successive charges. Some embodiments are specifically designed to unplug uncemented slotted liners and have very small gas generation capability.
