Apparatus for well completion
Well-completion apparatus is described for injecting fluids into earth formations for sand consolidation. The apparatus includes sealing means for isolating portions of a wall of a well bore, with these sealing means being appropriately arranged with means for perforating the wall portions to form a flow passage in the formation. Fluid- discharge means are arranged for selectively injecting one or more substances contained in the apparatus into the formation passage. To provide a reliable indication of the progress of the fluid injection, at least one of the fluent substances is made radioactive so that radioactivity- responsive monitoring means on the apparatus will provide a surface indication as these radioactive substances are discharged.
