Abstract: A method for artificial gas lift of a fluid from a well (202) includes lowering (2500) a tubing system (1900) into the well (202), wherein the tubing system (1900) includes an inner tubular string (402), and an outer tubular string (404) disposed concentrically around the inner tubular string (402); based on a flow amount of the fluid from the well, selecting (2502) an artificial gas lift process; reconfiguring (2504) the tubing system (1900), while in the well (202), to implement the selected artificial gas lift process; and lifting (2506) the fluid to the surface with the selected artificial gas lift process.

Abstract: A method for manufacturing a joint pipe element (300) of a well system includes providing (1900) an outer pipe (340) having a bore (341); providing (1902) an inner pipe (330) having a bore (331); placing (1904) the inner pipe (330) in the bore (341) of the outer pipe (340); and connecting (1906) the inner pipe (330) to the outer pipe (340) with a connecting mechanism (360) so that a rotational torque is transferred from the outer pipe to the inner pipe.

Abstract: A joint pipe element (322) for transporting a fluid in a well includes an outer pipe (340) having first threads (344) at a first end (340A); an inner pipe (330) having first threads (334) at a first end (330A), the inner pipe (330) being located inside the outer pipe (340); and plural lugs (360, 370) located between the outer pipe (340) and the inner pipe (330). The first threads (344) of the first end (340A) of the outer pipe (340) and the first threads (334) of the first end (330A) of the inner pipe (330) have the same number of teeth per unit length so that the outer pipe and the inner pipe are connected, simultaneously, by a single rotational motion, to another joint pipe element.
