Abstract: A process including the initial step of lowering a length of coil tubing down through the internal production bore, so that the end of the tubing which is at the depth of the preforations in the external casing, and a volume of fluid such as water is washed into the hole so that sand contained within the hole is washed out of the hole up through the annulus between the internal casing and the coil tubing. The coil tubing is then removed from the hole, and a second length of coil tubing is lowered into the hole with a blunt bottom gauge ring sub to approximately the same depth, and a quantity of ceramic beads are "squeezed" into the well bore so that the beads enter through the perforated tunnels and fill a zone exterior to the tunnels in the sand formation around the perforations.
