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.

First claim

What is claimed is:

1. A tubular comprising:
an outer surface and an inner surface defining a passage;
a plug arranged in the tubular blocking the passage, the plug having an annular seal that engages the inner surface and being formed from a disintegrating on demand (DOD) material;
an ignition device coupled to the plug, the ignition device comprising an activation member having a sensor and a power source, the ignition device being embedded in the plug and being selectively operable to deliver a detonation force to the plug; and
an excitation mechanism selectively operatively associated with the ignition device, the excitation mechanism comprising a pressure delivery system operable to deliver one or more pressure pulses into the passage to selectively detonate the ignition device creating the detonation force that breaks apart the plug.

2. The tubular according to claim 1 , wherein the ignition device directly abuts the plug.

3. The tubular according to claim 2 , wherein the ignition device is at least partially embedded in the plug.

4. The tubular according to claim 1 , wherein the sensor comprises a switch.

5. A resource exploration and recovery system comprising:
a first system;
a second system operatively connected to the first system, the second system including at least one tubular comprising:
an outer surface and an inner surface defining a passage;
a plug arranged in the tubular completely blocking the passage, the plug having an annular seal that engages the inner surface and being formed from a disintegrating on demand (DOD) material;
an ignition device coupled to the plug, the ignition device comprising an activation member having a sensor and a power source, the ignition device being embedded in the plug and being selectively operable to deliver a detonation force to the plug; and

an excitation mechanism selectively operatively associated with the ignition device, the excitation mechanism comprising a pressure delivery system operable to deliver one or more pressure pulses into the passage to selectively detonate the ignition device creating the detonation force that breaks apart the plug.

6. The resource exploration and recovery system according to claim 5 , wherein the ignition device directly abuts the plug.

7. A method of removing a plug having an annular seal formed from a disintegrate on demand (DOD) material secured in a passage of a tubular, the annular seal engaging an inner surface of the passage, the method comprising:
delivering an excitation force comprising a pressure pulse into the passage;
receiving the pressure pulse at an ignition device comprising an activation member including a sensor and a power source embedded in the plug;
triggering the power source based on the pressure pulse;
igniting the ignition device formed from DOD material with the power source;
detonating the ignition device with the pressure pulse to generate a detonation force; and
breaking apart the plug with the detonation force generated by the ignition device.

8. The method of claim 7 , wherein breaking apart the plug includes exploding the plug with the ignition device.
