teaching herein one or more of the boreholes represented by just two boreholes 12 and 14 for simplicity in illustration is configured with one or more permeability control devices 32 that are each configured differently with respect to permeability or pressure drop in flow direction in or out of the tubular the devices 32 nearest the heel 18 or 28 will have the least permeability while permeability will increase in each device 32 sequentially toward the toe 20 and 30 the permeability of the device 32 closest to toe 20 or 30 will be the greatest this will tend to balance outflow of injected fluid and inflow of production fluid over the length of the borehole 12 and 14 because the natural pressure drop of the system is opposite that created by the configuration of permeability devices as described permeability and or pressure drop devices 32 useable in this configuration include inflow control devices such as product family number h48688 commercially available from baker oil tools houston tex beaded matrix flow control configurations such as those disclosed in u s ser nos 61 052 919 11 875 584 and 12 144 730 12 144 406 and 12 171 707 the disclosures of which are incorporated herein by reference or other similar devices adjustment of pressure drop across individual permeability devices is possible in accordance with the teaching hereof such that the desired permeability over the length of the borehole 12 or 14 as described herein.
