    Abstract: An apparatus for hydrocarbon recovery from a production well includes a pump, a motor for driving the pump, and an intake and gas separator between the motor and the pump, in the production well, such that the gas separator is coupled to the pump and is located closer to the wellhead than the motor and the intake is disposed between the gas separator and the motor. A production conduit extends inside the production well casing, from an outlet of the pump to a second end at the wellhead to facilitate pumping of liquid from a discharge outlet of the gas separator, through the production well casing, to the wellhead, and tubing is in fluid communication with a gas outlet of the gas separator and extends to expel gas received from the gas separator, at a location above a liquid level in the production well.
