Abstract: A downhole tool, a nozzle assembly for the downhole tool and a nozzle. The nozzle assembly includes an orifice in a housing of the downhole tool. The orifice has a housing groove. A nozzle is insertable into the orifice, the nozzle including a nozzle groove. A release member secures the nozzle to the housing by disposing a first portion of the release member in the housing groove and a second portion of the release member in the nozzle groove. The first portion is removable from the second portion upon applying a force to the nozzle above a release threshold. The nozzle includes a body having an outlet end, a nozzle groove on a surface of the body for receiving a release member to secure the nozzle within a housing, and a seal groove for isolating the nozzle groove from an environment at the outlet end.

Abstract: A system for degrading a structure includes the structure formed of a degradable-on-demand material, an ignitor arranged to transfer heat to the structure; and, a mechanical impactor movable with respect to the structure, wherein the ignitor increases in temperature upon impact of the mechanical impactor into the ignitor, and heat from the ignitor initiates degradation of the structure.

Abstract: A tubular includes an outer surface and an inner surface defining a passage. A plug is arranged in the tubular blocking the passage. The plug is formed from a disintegrating on demand (DOD) material. An ignition device is coupled to the plug. An excitation mechanism is selectively operatively associated with the ignition device. The excitation mechanism selectively activates the ignition device to break apart the plug.

Abstract: A downhole assembly includes a downhole tool including a degradable-on-demand material including: a matrix material; and, a unit in contact with the matrix material. The unit includes a core including an energetic material configured to generate energy upon activation to facilitate degradation of the downhole tool; and, an activator disposed in contact with the core, the activator including a triggering system having an electrical circuit and an igniter within the electrical circuit, the electrical circuit having an open condition and a closed condition, the electrical circuit configured to be in the closed condition after movement of an object downhole that engages directly or indirectly with the triggering system, and the igniter arranged to ignite the energetic material in the closed condition of the electrical circuit. In the open condition of the electrical circuit the igniter is inactive, and in the closed condition of the electrical circuit the igniter is activated.

Abstract: A downhole assembly includes a matrix material and a unit in contact with the matrix material. The unit includes a core having an energetic material, an activator disposed in direct contact with the core, and at least one layer disposed on the core. The activator includes a triggering system having an igniter and a pre-set timer connected in an electrical circuit. The igniter is inactive in an open condition of the electrical circuit, and, after a pre-set time period, the pre-set timer closes the electrical circuit and the igniter is activated.
