    摘要: An apparatus for stimulating a subterranean formation includes a first tube, a second tube, a combustion body and an ignition propagator. The second tube is positioned within the first tube interior and the second tube interior is sealed from the first tube interior to substantially prevent fluid communication between the first tube interior and the second tube interior. The combustion body is formed from a solid propellant and is positioned within the first tube interior external to the second tube interior. The ignition propagator is positioned within the second tube interior and is substantially free from fluid contact with fluid residing in the surrounding environment external to the first tube wall.

    摘要: A method for stimulating a subterranean formation which is penetrated by a well bore having casing positioned therein so as to establish fluid communication between the formation and the well bore. Propellant is secured to the outer surface of a carrier having a plurality of apertures formed therein. Detonating cord is positioned within said carrier and when ignited causes the propellant to ignite initially at each aperture. In this manner, the propellant is caused to burn in controlled, uniform manner. Upon burning, the propellant generates gases which clean perforations previously formed through the casing into the formation and which extend fluid communication between the formation and the well bore.

    摘要: A method of creating a seismic wave in a subterranean environment wherein solid propellant material is positioned in a subterranean well and ignited thereby generating a seismic wave. The seismic wave is recorded at distance from where the propellant material is ignited by means of geophones or similar recording devices. The propellant material is geometrically configured with the assistance of computer modeling. The pressure generated by the ignition is recorded in the well and used to validate the computer model for configuring subsequent propellant material employed as a seismic source.
