Abstract
An annular restrictor for use in a well can include a body which extends circumferentially about a tubular mandrel, and a section which, in cooperation with the body, restricts fluid flow through an annulus, a line being secured between the body and the section. A method of completing a well can include installing a line in an annular restrictor, and restricting fluid flow through an annulus, with the restricting being performed by the annular restrictor interconnected between steam injection valves. A method of attaching a line to a tubular string for use in a well can include covering the line with a section of an annular restrictor, and securing the section to a body of the annular restrictor, each of the section and the body having a flow restricting surface formed thereon, and the covering and securing steps being performed without splicing or making a connection in the line.
