Plug
An improved plug for sealing a tubular as described. The improved plug comprises a plug body, the plug body comprising a propellant and an initiator adapted to initiate the propellant upon a signal. Upon initiation the propellant deflagrates causing the plug body to at least partially disintegrate.
1. An improved plug for sealing a tubular; the improved plug comprising: a plug body, the plug body comprising a propellant and at least one other material; and
an initiator adapted to initiate the propellant upon a signal;
wherein upon initiation the propellant deflagrates causing only the propellant to at least partially disintegrate, disintegration of the propellant causing the plug body to at least partially collapse.
2. The plug of claim 1 , wherein the plug body fully comprises the propellant.
3. The plug of claim 1 , wherein the plug further comprises a housing, the housing adapted to receive the plug body.
4. The plug of claim 3 , wherein the housing is adapted to engage, in use, a tubular wall.
5. The plug of claim 1 , wherein the plug further comprises one or more sensors.
6. The plug of claim 5 , wherein the plug further comprises a transmitter adapted to transmit information from location to the surface.
7. An improved plug for sealing a tubular; the improved plug comprising: a plug body, the plug body comprising a consumable and at least one other material; and
an initiator adapted upon a signal to expose the consumable to a condition in which the consumable will be consumed causing only the consumable to disintegrate, disintegration of the consumable causing the plug body to at least partially collapse.
8. An improved tool for sealing a tubular; the improved tool comprising: a tool body, the tool body comprising a consumable and at least one other material; and an initiator adapted upon a signal to expose the consumable to a condition in which only the consumable will be consumed, causing the consumable to at least partially disintegrate, disintegration of the consumable causing the plug body to at least partially collapse.
9. An improved tool for use downhole; the improved tool comprising:
a tool body, the tool body comprising a propellant, and at least one other material; and
an initiator adapted to initiate the propellant upon a signal;
wherein upon initiation the propellant deflagrates causing only the propellant to at least partially disintegrate disintegration of the propellant causing the tool body to at least partially collapse.
10. The tool of claim 9 , wherein the tool further comprises one or more sensors.
11. The tool of claim 10 , wherein the tool further comprises a transmitter, transmitter being adapted to transmit information from the sensors to a remote location such as surface.
