Abstract
Method and system for use in a subsurface formation traversed by a wellbore. An energized fluid, which when subjected to a low pressure environment liberates or releases gas from solution, is disposed in the formation. Reduced pressure in a region of the wellbore below pressure in the surrounding formation liberates a gas in the energized fluid near a tunnel created in the formation.
