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.

Abstract: A perforating system for creating perforations that azimuthally circumscribe an inner wall of a wellbore, and that are at substantially the same depth in the wellbore. The perforating system includes perforating assemblies that are housed in a gun body and spaced axially apart. The perforating assemblies have shaped charges positioned at selective angles around an axis of the gun body and at substantially the same axial location in the gun body. Bulkheads are provided between adjacent shaped charges, so that initiating the shaped charges forms angularly spaced apart perforations in a tubular in which the perforating system is inserted. Pressurizing the wellbore with fracturing fluid extends the perforations into fractures, where the fractures are normal to an axis of the wellbore and in a plane of minimum stress.

Abstract: A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.

The multilayered unit can be embedded in a component, attached to a component, or disposed between two components of a downhole assembly. The downhole assembly containing the multilayered unit has controlled disintegration in a downhole environment.

Abstract: An intelligent dart or ball or other shape is dropped or pumped into a borehole that has multiple valves for access to the formation through which fractures are initiated. The intelligent object engages with the valves as it passes with retractable engagement dogs that are outwardly biased but not to the degree needed to find support unless the valve in question is the one that needs to be operated. In that event the dogs become supported and pressure is applied to the object to shift the valve to the open position. The object can be released at a later time remotely or can be milled out. Subsequent objects can be landed in the same sleeve after the initial object is released to close it or to close the open port by moving a second sleeve against a first sleeve. Fracturing in any order is envisioned.

Abstract: A sleeve apparatus having a longitudinal axis and an interior further includes a tubular having a plurality of ports providing a length of fluidic access between the interior and an exterior of the tubular, the length measured with respect to the longitudinal axis; and, a sleeve disposed within the tubular and configured to move longitudinally with respect to the longitudinal axis. The sleeve further has a plurality of apertures misaligned with the plurality of ports in a closed condition of the sleeve apparatus and at least substantially aligned with the plurality of ports in a fully open condition of the sleeve apparatus, and a plurality of non-apertured sections aligned with the plurality of ports in the closed condition. A longitudinal shifting distance of the sleeve to move the sleeve apparatus from the closed condition to the fully open condition is less than the length of fluidic access.
