A lined tubular system and method provides for the manipulation and control of annular fluids tubular and the liner. This structure allows for profiling of the exterior wall of a liner such that one or more continuous channels are provided along the length of the lined tubular system. The system may also include one or more non-crushable members or tubes between the liner's exterior surface and host tubular's interior surface. Rounded, granular particles in the annulus between liner and host may provide an alternative path for fluid flow. The particles may be uniformly or randomly distributed in the annulus.

[ What is claimed is:] [1.]1. A composite downhole tubular system comprising:a. a downhole host tubular;b. a polymeric liner located in the host tubular and in partial abutting contact with host tubular; andc. a channel between the polymeric liner and the host tubular; andwherein the channel is formed by multiple non-contiguous protrusions extending from the liner toward the host tubular and created on the outer surface of the liner.
