Abstract: Artificial lift systems, methods, and apparatuses are described. An example artificial lift system may include a plunger have an energy-storing component to store energy as the plunger descends through a wellbore and release the stored energy as the plunger ascends through the wellbore. The energy-storage component may be a spring. The spring may be compressed in response to rotation of a propeller coupled to the spring. The propeller may rotate in a first direction in response to interaction of the propeller and a liquid in the wellbore as the plunger descends. The spring may expand during uphole movement of the plunger to rotate the propeller in a second direction, opposite the first direction, and assist in lifting the plunger to the surface.

Abstract: An inverted Y-tool is positioned in multiphase wellbore fluid flowing through a wellbore. The inverted Y-tool separates at least a portion of gas from the multiphase wellbore fluid and, after separating at least the portion of the gas from the multiphase wellbore fluid, directs the multiphase wellbore fluid to a downhole pump that pumps the wellbore fluid in an uphole direction.

Abstract: A downhole fluid separator includes a first tubular including a volume defined between an open, uphole end of the first tubular opposite an open, downhole end of the first tubular, the volume of the first tubular including a fluid pathway configured to receive a mixed-phase fluid from an annulus of a wellbore and provide separate flows of a gas and a liquid to the uphole end of the first tubular; a second tubular including a volume configured to receive at least a portion of a downhole artificial lift device through an open, uphole end of the second tubular opposite a closed, downhole end of the second tubular, and an adjustable opening formed in a portion of the second tubular at a location between the uphole and downhole ends and configured to selectively receive the flow of the liquid into the volume of the second tubular; and an actuatable wellbore seal positioned around each of the first and second tubulars and between the first and second tubulars, downhole of the adjustable opening, and between the uph
