Claim 7:
8. An apparatus comprising:
a housing configured to be disposed downhole within a wellbore formed in a subterranean formation, the housing configured to couple to a wireline, the housing comprising a door configured to switch between a closed position and an open position;
solidified nitrogen disposed within the housing, the solidified nitrogen encapsulated by an emulsifying agent configured to dissolve in response to exposure to a downhole fluid; and
a controller coupled to the housing, the controller configured to switch the door from the closed position to the open position in response to the housing reaching a specified downhole location within the wellbore, thereby exposing the solidified nitrogen encapsulated by the emulsifying agent to the downhole fluid at the specified 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.
