Abstract: An interlocking independent tubular with multiple circumferential sections allows a borehole to advance by encasing with a single pass, the structurally independent tubular. The independent tubular is single layered, having a major arc and a minor arc forming circumferential sections. The minor arc may be defined by less than 180 degrees, and the major arc may be a circumferential section defined by greater than 180 degrees. The major arc and minor arc align longitudinally to form the independent tubular. Installation may involve partially radially collapsing the major arc, inserting the major arc and minor arc through a previously installed tubular, reexpanding the major arc and connecting the major arc and minor arc to form the independent tubular downhole from the previously installed tubular, and joining the independent tubular to the previously installed tubular. The tubes may be joined by interlocking female and male ends of the tubes.
