A new and superior gravel packing method called ALLPAKTM. for alternate path gravel packing, is reported here. It has been found that gravel packing problems associated with formation of sand bridges in the annulus outside the screen can be eliminated by adding alternate flow paths for slurry flow. The alternate paths are provided by perforated shunts or secondary piping placed in the annulus, usually by attaching the tubes to the screen. Laboratory gravel pack simulator tests indicate that essentially complete annulus packs can always be obtained, even in cases where current methods provide very poor pack efficiencies. This paper describes the laboratory experiments and field tests which verify the advantages from this new concept. |
