Abstract
A method of stimulating a subterranean formation. The method begins with positioning a stimulation tool into a wellbore formed through the formation. The stimulation tool includes (i) at least one tubular segment; (ii) an outer sleeve positioned on the tubular segment and forming an annular space between the tubular segment and the outer sleeve; (iii) a propellant positioned within the annular space; (iv) at least one ignitor positioned to ignite the propellant; (v) at least one rupture disc positioned within a wall of the tubular segment; and (vi) the absence of a detonator for detonating the propellant. Thereafter, the propellant is ignited to begin deflagration of the propellant.
