.~.~ Fluid injected from longitudinally spaced locations in injection well
DEFINITION
Classification: 166/269
(under subclass 268) A process in which fluid material is introduced into the pores of the earth from locations in an input well which are spaced from each other along the longitudinal axis of the well, i.e., vertically spaced in the ordinary well having a vertical axis.
(1) Note. A location which is packed off from another location is considered longitudinally spaced. A single group of holes in a well conduit is not considered to provide longitudinally spaced locations, but longitudinally spaced groups of holes do provide spaced locations. Fluid introduced from an uncased portion of a well is considered to be introduced from a single location.
(2) Note. A claim which calls for separate introduction of fluids at locations longitudinally arranged in the well is considered to meet the definition since such claim inherently requires the use of a packer or equivalent means to effect the separate introduction.
