Fisher, Jr, H H; Myers, W D; Chenoweth, D V

In an apparatus for injecting fluid through perforations in a subsurface well casing, a plurality of spaced packings on a supporting body are adapted to seal against the casing to form a plurality of separated zones isolated from one another and straddling the casing perforations. A separate flow path is provided from a body passage to each zone. This flow path includes elongate tubing for controlling the rate at which fluid discharges into each zone. A limit valve also is provided in each flow path for limiting the maximum fluid pressure that can be imposed in each zone and on the surrounding well formation. (16 claims)
