Abstract: A device that allows gradually regulation, i.e., non-destructively controlling the flow of injected polymer flooding enhanced oil recovery fluids at each point of injection, using: at least one conduit providing a variable length flow path combined with the centrifugal and other retarding or decelerative forces accessible to a formation engineer by configuring and otherwise arranging the spatial orientation and relative position of each section of such conduit, so as to achieve a never before attained degree of non-damaging flow control density within a compact space.
