发明名称 Energized fluid for generating self-cleaning filter cake
摘要 A process for generating and subsequently breaking a filter cake, including dissolving a non-reactive gas in a wellbore fluid to form an energized fluid; pumping the energized fluid into a formation at a downhole pressure, wherein the pumping is at overbalanced conditions; producing a filter cake; and decreasing the down hole pressure to below a cut point of the dissolved gas in the energized fluid to form a vapor phase, wherein the vapor phase compromises the integrity of the filter cake is disclosed.
