Abstract
A dual flow/multi-flow pipe assembly for use in hydrocarbon recovery processes, having alternately-spaced apertures along a length thereof separated by packer elements, wherein alternating apertures fluidly connect with separate flow channels within the pipe assembly. A first embodiment is of a pipe-in-pipe configuration, with tubular members respectively located in alternately-spaced apertures fluidly connecting an interior pipe member with an exterior of the pipe assembly, and remaining spaced apertures fluidly connecting said exterior with an annular region between the interior pipe and the outer pipe, A second embodiment is of the divided pipe configuration, wherein a longitudinally extending divider partition is provided in each pipe member making up the multi-flow pipe assembly thereby forming two separate flow channels within each pipe member, with alternately spaced apertures fluidly communicating with a respective of the two or more flow channels formed within each pipe member by the divider partition.
