A wellhead adaptor for fluidly connecting to a well tubing system, the wellhead adaptor including an outer body having a bore; and an inner body located inside the bore and having an annulus A. The inner body and the outer body define an annulus B, which is concentric to annulus A.

Wellhead adaptor for dual concentric tubing for well operations

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.

Artificial lift method and apparatus for horizontal well

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.

A non-linear shaped charge perforator for use in perforating an oil and gas formation into which a wellbore has been drilled comprises a monolithic, axisymmetric metal case in which is disposed a main explosive charge between the front of the case, which is closed with a concave metal liner, and the closed back end of the case. The main explosive charge contains multiple initiation points, preferably two initiation points located about 180&#xb0; apart on the outside surface of the charge, so that when the perforator is detonated the main charge is initiated such that the metal liner is collapsed into a non-circular jet, preferably a fan-shaped jet, that pierces the casing of the wellbore and forms non-circular perforations, preferably slot-shaped perforations, in the surrounding formation.
