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.

Abstract: A downhole assembly includes a downhole tool including a degradable-on-demand material and a triggering system. The degradable-on-demand material includes a matrix material and an energetic material configured to generate energy upon activation to facilitate the degradation of the downhole tool. The triggering system includes an igniter arranged to ignite the downhole tool, an electrical circuit, and a pre-set timer. In an open condition of the circuit the igniter is not activated, and in a closed condition of the circuit the igniter is activated. The pre-set timer is operable to close the electrical circuit after a pre-set time period.
