ABSTRACT:
This invention relates to enhancing hydrocarbon production from a subterranean formation via a well completed with a gravel pack. Gravel packs suffer plugging and damage over time from produced particles and other plugging materials brought into the pack as production continues. This invention relates to a chemical treatment for the gravel pack designed to remove damaging particulate matter from the pack via dissolution or displacement. Damaging material is forced sufficiently far into the producing reservoir to prevent its remigration back into the pack.
