What is presented is a combustible pellet for creating heated gas. The combustible pellet is insertable into a cutting apparatus or a high power igniter or both. The combustible pellet is compacted to be resistant to mechanical damage and is resistant to unintentional ignition. The combustible pellet is ignitable without a loose powdered form of combustible material when the combustible pellet is in the cutting apparatus or the high power igniter.

The invention is directed to a radiation curable energetic composition, to a method of forming a three-dimensional energetic object, to a three-dimensional energetic object, and to uses of the radiation curable energetic composition. The radiation curable energetic composition of the invention comprises (a) one or more polymerisable components, (b) one or more polymerisation photoinitiators, and (c) one or more energetic components.

What is presented is a high power igniter that releasably secures to a cutting apparatus that is used for radially projecting a flow of heated gas to cut from an internal surface through an external surface of a conduit used for oil, gas, mining, and underwater pressure sealed tool applications. The high power igniter comprises an igniter housing adapted to be positioned in the conduit. The igniter housing comprises a containment sub and a nozzle sub that releasably secure to each other. The nozzle sub for directing the flow of the heated gas toward the cutting apparatus and releasably securing to the cutting apparatus. A high wattage heater in the igniter housing comprises a metal magnalium thermite pellet insertable into the igniter housing for creating the flow of heated gas when the high power igniter is in use and a pellet igniting device.

Systems and methods for releasing a material into an environment. The material may be encapsulated in a receptacle or otherwise packaged for movement into the environment. The receptacle with the material inside is introduced into the environment. A triggering causes release of the material from the receptacle into the environment.

The present invention is directed to an explosive composition comprised of heavy ANFO and expanded polymeric beads that have a density that is less than the density of the heavy ANFO. The expanded polymeric beads have a size that is determined or based on the size of ammonium nitrate prills used in the heavy ANFO portion of the composition. In one embodiment, the expanded polymeric beads that are utilized in the composition are at least 70% of the lower limit of the mesh size of the predominant ammonium nitrate prill mesh size. In another embodiment, the expanded polymeric beads are at least 70% of a size that is related to the average mesh size of the ammonium nitrate prills.
