Title:
ANNULAR FLUID MANIPULATION IN LINED TUBULAR SYSTEMS
Document Type and Number:
WIPO Patent Application WO2000005506
Kind Code:
A3
Abstract:
A lined tubular system and method provides for the manipulation and control of annular fluids in channels (18) between the tubular (10) and the liner (17). 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 or spacers in the annulus between the liner and host may provide an alternative path for fluid flow. The particles or spacers may be uniformly or randomly distributed in the annulus.
