Claim 12:
13. A system comprising:
a wellbore formed in a subterranean formation;
a housing;
a wireline extending from a surface location to a downhole location within the wellbore, the housing coupled to the wireline at the downhole location;
a cartridge disposed within the housing;
solidified nitrogen encapsulated by an emulsifying agent, the solidified nitrogen encapsulated by the emulsifying agent disposed within the cartridge, the emulsifying agent configured to dissolve in response to exposure to a downhole fluid; and
a charge disposed within the housing and connected to the cartridge, the charge configured to detonate to release the solidified nitrogen encapsulated by the emulsifying agent from the cartridge to the wellbore, thereby exposing the solidified nitrogen encapsulated by the emulsifying agent to the downhole fluid at the downhole location within the wellbore, dissolving the emulsifying agent, and sublimating the solidified nitrogen into nitrogen gas which is released into the wellbore and reduces hydrostatic column in the wellbore.
