Claim 0:
1. A method comprising:
placing solidified nitrogen at a downhole location within a wellbore formed in a subterranean formation, wherein the solidified nitrogen is encapsulated by an emulsifying agent configured to dissolve in response to exposure to a downhole fluid;
exposing the solidified nitrogen encapsulated by the emulsifying agent to the downhole fluid at the downhole location within the wellbore, thereby dissolving the emulsifying agent and releasing the solidified nitrogen;
allowing the solidified nitrogen to sublimate into nitrogen gas within the wellbore, thereby reducing hydrostatic column in the wellbore; and
producing the downhole fluid from the wellbore to a surface location.
