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.

Abstract: A downhole assembly includes a downhole tool including a degradable-on-demand material including: a matrix material; and, an energetic material configured to generate energy upon activation to facilitate the degradation of the downhole tool; and, a triggering system including: an 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, an igniter within the electrical circuit, the igniter arranged to ignite the downhole tool 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 packer device includes a central packer mandrel and radially surrounding expansion mandrel that carries a suitable engagement profile for engaging the surrounding casing or other tubular member. A material chamber is defined between the expansion mandrel and the packer mandrel and is filled with a filler material. In currently preferred embodiments, the filler material comprises a pliable solid, a gel or colloid, or a liquid. A setting mechanism radially expands the expansion mandrel so that the engagement profile of the expansion mandrel is brought into engagement with the surrounding tubular.

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.
