20090151949 | DEBRIS-FREE PERFORATING APPARATUS AND TECHNIQUE - An apparatus that is usable with a well includes a perforating system that is adapted to be fired downhole in the well. The perforating system includes a component, which includes an alloy that has a negative corrosion potential and is unable to passivate, or self-protect, while deployed in the well. The component is adapted to disintegrate to form substantially no debris in response to the firing of the perforating system. | 06-18-2009 |
20100012321 | COMMUNICATING THROUGH A BARRIER IN A WELL - A technique that is usable with a well includes communicating a ballistic wave from a first point in a well to a second point in the well without propagating the ballistic wave along a detonating cord. The first and second points are separated by at least one foot. The technique includes responding to the ballistic wave near the second point to activate a downhole tool. | 01-21-2010 |
20110094406 | Dissolvable Material Application in Perforating - A shaped charge includes a charge case; a liner; an explosive retained between the charge case and the liner; and a primer core disposed in a hole in the charge case and in contact with the explosive, wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid. A perforation system includes a perforation gun, comprising a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises a material soluble in a selected fluid. | 04-28-2011 |
20110239889 | DETONATION TO IGNITER BOOSTER DEVICE - A detonating device includes a high explosive portion comprising high explosive; a low explosive portion comprising low explosive; and a transition portion between the high explosive portion and the low explosive portion, wherein the transition portion comprises a mixture of high explosive and low explosive. | 10-06-2011 |
20120018157 | BALLISTIC TRANSFER DELAY DEVICE - A ballistic transfer delay device and method of use. The ballistic transfer delay device does not include a firing pin and it is not pressure initiated. The device comprises a time delay fuse, a through-bulkhead initiator to initiate the time delay fuse, and an output booster to ballistically transfer the energy from the initiated time delay fuse. | 01-26-2012 |
20120160491 | METHOD AND DESIGN FOR HIGH SHOT DENSITY PERFORATING GUN - A perforating gun includes a plurality of shaped charges located at a first distance from a detonator along a plurality of detonating cords and forming a first group, wherein the first group of shaped charges is configured to be detonated simultaneously. The plurality of detonating cords are of the same length. | 06-28-2012 |
20130087061 | DISSOLVABLE MATERIAL APPLICATION IN PERFORATING - A shaped charge includes a charge case; a liner; an explosive retained between the charge case and the liner; and a primer core disposed in a hole in the charge case and in contact with the explosive, wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid. A perforation system includes a perforation gun, comprising a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises a material soluble in a selected fluid. | 04-11-2013 |
20140151046 | DISSOLVABLE MATERIAL APPLICATION IN PERFORATING - A shaped charge includes a charge case; a liner; an explosive retained between the charge case and the liner; and a primer core disposed in a hole in the charge case and in contact with the explosive, wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid. A perforation system includes a perforation gun, comprising a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises a material soluble in a selected fluid. | 06-05-2014 |
