Abstract
Methods and apparatus managing energy release in energetic perforating devices, such as perforating guns, for example. In some embodiments, the methods comprise deploying the energetic perforating device having an explosive into a wellbore, removing air from an interior volume of the energetic perforating device, placing the energetic perforating device into the wellbore, and forming a perforation in the wellbore with the energetic perforating device by detonating the explosive, wherein the removing of the air limits reaction of the explosive.
Claims20
A method of deploying an energetic perforating device having an explosive into a wellbore, the method comprising:
- placing wadding in an interior volume of the energetic perforating device, wherein the energetic perforating device comprises a perforating gun, a capsule gun, or a jet cutter;
- removing air from the interior volume;
- placing the energetic perforating device into the wellbore, wherein the wellbore is in a subterranean formation;
- and
- forming a perforation in the wellbore with the energetic perforating device by detonating the explosive, wherein the removing of the air limits reaction of the explosive, thereby limiting production of heat due to the reaction.
A method of deploying an energetic perforating device having an explosive into a wellbore, the method comprising:
- removing air from an interior volume of the energetic perforating device using an oxygen scavenger,
- placing the energetic perforating device into the wellbore, wherein the wellbore is in a subterranean formation, and wherein the energetic perforating device comprises a perforating gun, a capsule gun, or a jet cutter;
- and
- forming a perforation in the wellbore with the energetic perforating device by detonating the explosive, wherein the removing the air limits reaction of the explosive, thereby limiting production of carbon dioxide in the energetic perforating device caused by the reaction.
A method of deploying an energetic perforating device having an explosive into a wellbore, the method comprising:
- removing air from an interior volume of the energetic perforating device using an oxygen absorbing component in the interior volume;
- placing the energetic perforating device into the wellbore;
- and
- forming a perforation in the wellbore with the energetic perforating device by detonating the explosive, wherein the removing the air or the inhibiting the external air, or the combination thereof, limits reaction of the explosive.
