A packer assembly for a production well is described. The packer assembly includes one or more packer elements set to engage and seal the inner surface of a well casing, where a production tube runs through the one or more packer elements and provides a fluid path to the surface. A chemical inlet above the one or more packer elements connects to a chemical flow path through the one or more packer elements and a chemical outlet below the packer assembly.
