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 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 method of manufacturing a valve of a tool for use downhole includes changing a flow characteristic of the valve. A load is applied to a first nozzle secured in a housing of the valve via a first release member, wherein a magnitude of the load is greater than a release threshold of the first release member, to release the first release member. The first nozzle is removed from the housing, and a second nozzle is secured in the housing via a second release member.

Abstract: A downhole element for use in a wellbore with a wellbore fluid. The downhole element includes a body formed from a dissolvable material to degrade at a first rate when exposed to the wellbore fluid, with at least one cavity defined by the body. A degradation agent is disposed within the at least one cavity. The at least one cavity selectively releases the degradation agent and the degradation agent degrades the body at a second rate when exposed to the wellbore fluid and the dissolvable material.
