Well-completion apparatus for injecting fluids into earth formations includes appropriately arranged sealing members adapted for isolating a wall of a well bore and 2 or more spaced perforating devices adapted to perforate spaced portions of an isolated well-bore wall and form a circuitous flow passage in the formation. Fluid-discharge means are arranged in the apparatus for injecting selected fluid agents (for example, formation-consolidating materials) into the flow passges through one of these isolated portions either in conjunction with, or subsequent to, the withdrawal of loosened debris and the like in the pasages by way of the other isolated portion. The debris is withdrawn from the flow passages and through the other isolated portion and received in an enclosed chamber on the apparatus which is opened upon command from the surface. (9 claims)
