Abstract
An artificial lifting system for bringing a formation fluid from a horizontal well to the surface, the system including an outer production tubing that extends into the well, from a head of the well to a lateral portion of the well; and a hybrid valve attached to a distal end of the outer production tubing. The hybrid valve has two orientations, a first orientation for which the hybrid valve acts as a one-way valve, and a second orientation for which the hybrid valve acts as a conduit.
