Abstract
Wellbore assembly for injecting fluid into a subsurface formation having multiple intervals comprising a plurality of packers having bypass channels at desired locations between the respective intervals. The assembly allows fluid to be injected down a tubing string, back up an annular region, and through the series of packers to impart incremental pressure drops along the intervals. The assembly enhances pressure support by allowing the operator to optimize wellbore injection along intervals having different formation characteristics.
