A method of recovering liquid petroleum gases (LPGs) from a wellbore includes: performing a well treatment operation by injecting the LPGs into the wellbore to increase the wellbore pressure; flowing a fluid stream from the wellhead into a separation vessel, the fluid stream comprising the LPGs; reducing the pressure of the fluid stream from the wellbore pressure to a separation vessel pressure, the fluid stream in the separation vessel comprising the LPGs in liquid form and in vapour form; separating the vapour form from the liquid form; transferring the liquid form of the LPGs to a pressure vessel; and passing the vapour form through a condenser to condense the vapour form, and depositing the condensed vapour form into the pressure vessel.

A subterranean method of processing a hydrocarbon fluid-containing deposit includes, from a subterranean room, providing a borehole into a deposit containing formation fluid comprising fluid hydrocarbon. The borehole has a first end at a wall of the subterranean room, and a second end remote from the subterranean room and received within the deposit. The first end is elevationally lower than the second end. A string of pipe is provided within the borehole from the subterranean room. A cuttings removal fluid is injected from the string of pipe into the borehole and against a wall of the borehole in underbalanced pressure conditions. One of drilling, reaming, or jetting is conducted within the borehole during said injecting of the cuttings removal fluid. Formation fluid comprising fluid hydrocarbon is flowed from the deposit into the borehole during said injecting of the cuttings removal fluid. The injected cuttings removal fluid and the formation fluid within the borehole are flowed at least in part by gravity downhole externally of the string of pipe in underbalanced pressure conditions within the borehole and into the subterranean room. Other implementations and aspects are contemplated.
