Abstract
An artificial lifting system for bringing a formation fluid from a horizontal well to the surface. The system includes an outer production tubing that extends into the well, from a head of the well to a toe of a lateral portion of the well; and an extraction support mechanism extending in a bore of the outer production tubing.
Claims20
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 toe of a lateral portion of the well;
- and
- an extraction support mechanism extending in a bore of the outer production tubing.
A method for artificial lifting a formation fluid from a horizontal well to the surface, the method comprising:
- lowering into the well an outer production tubing and an extraction support mechanism, wherein the extraction support mechanism is located inside a bore of the outer production tubing and a distal end of the outer production tubing extends to a toe of a horizontal part of the well;
- and
- lifting the formation fluid through at least one of a casing of the well, or the outer production tubing or the extraction support mechanism.
