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.

An artificial lifting system for bringing a formation fluid from a horizontal well to the surface, the system comprising:
- an outer production tubing that extends into the well, from a head of the well to a lateral portion of the well;
- a hybrid valve attached to a distal end of the outer production tubing;
- and
- an extraction support mechanism extending in a bore of the outer production tubing,
- wherein 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, and
- wherein the extraction support mechanism is an inner production tube that does not contact the hybrid valve.
