A system for lifting formation fluids in a wellbore includes a valve linking an intake and a collection area, wherein when the valve is open the fluids are able to flow from the intake to the collection area, and wherein when the valve is closed the fluids are able to be lifted through velocity tubing via injection means. The collection area includes the micro annulus between the velocity tubing and production tubing, and the injecting means is a high pressure gas injected through the micro annulus to cause the valve to close and the fluid to be lifted through the velocity tubing. Optionally, blow out components can be included allowing the system to be implemented in a live well. An associated method is also provided, including the steps of deploying a valve near an intake, allowing fluids to flow from the intake through the valve to a collection area, and injecting gas to the collection area at pressure sufficient to close the bottom valve and lift the fluids through velocity tubing.
