Abstract: A process for isolating one or more segments of a gravel packed well from other segments to treat the isolated segments and easily re-establish flow from the other segments after the treatment is described. The treatment includes techniques for enhancing or permanently blocking production from the isolated segment. The process includes the installation of a removable sealing element and a permeability poison that forms a fluid seal to prevent longitudinal fluid flow along the annular production space outside the tubular production pipe. With wireline or other low-cost wellbore workover systems, access is re-engaged with the secluded formation including removal of plugs and fluid seals within the tubular production pipe.
