대표청구항 ▼

What is claimed is: 1. A method for use in a subsurface formation traversed by a wellbore, comprising: disposing an energized fluid in a formation surrounding a region of the wellbore; liberating a gas from the energized fluid disposed in the formation in response to reducing pressure in the region of the wellbore below pressure in the formation; and flowing debris from the formation into the wellbore in response to liberating the gas from the energized fluid. 2. The method of claim 1, further comprising creating a tunnel in the formation, wherein the energized fluid is disposed in the formation before creating the tunnel in the formation. 3. The method of claim 2, wherein reducing the pressure in the wellbore is performed when creating the tunnel in the formation. 4. The method of claim 3, wherein creating the tunnel in the formation comprises creating an opening in casing disposed in the wellbore. 5. The method of claim 4, wherein reducing the pressure in the region of the wellbore comprises opening at least one port to a sealed container disposed in the wellbore. 6. The method of claim 5, wherein the energized fluid comprises one selected from a liquid, a foam, and a liquefied gas. 7. The method of claim 1, wherein the energized fluid is disposed in the formation after creating the tunnel in the formation. 8. The method of claim 7, wherein reducing the pressure in the region of the wellbore comprises opening at least one port to a sealed container disposed in the wellbore. 9. The method of claim 8, wherein the energized fluid comprises one selected from a liquid, a foam, and a liquefied gas. 10. The method of claim 1, wherein the energized fluid comprises one selected from a liquid, a foam, and a liquefied gas.
