Abstract
A system includes a casing, a tubing within the casing, a packer, and a colloidal silica gel. The casing inner surface and the tubing outer surface define an annular space, and the packer is within the annular space. The colloidal silica gel which seals a gap. The gap can be a gap between the inner surface of the casing and a surface of the packer, a gap between the outer surface of the tubing and a surface of the packer, and/or a gap extending through the packer. A well can include such a system. A method of sealing a leak in or near a packer present in an annular space between a production casing inner surface and a tubing outer surface includes disposing a composition within the annular space, the composition comprising colloidal silica, water, and an activator. The method also includes allowing colloidal silica to precipitate from the composition to provide a colloidal silica gel within the annular space, wherein the colloidal silica seals a gap that can be a gap between the inner surface of the production casing and a surface of the packer, a gap between the outer surface of the tubing and a surface of the packer, and/or a gap extending through the packer.
