Three commercial scale dissolver formulations were tested, along with laboratory prepared amino carboxylic acid scale dissolvers, to assess their comparative ability to dissolve barium sulfate and potential to cause formation damage in the near-wellbore formation. The potential formation damage capacity was assessed by measuring the levels of cation release in static tests on mineral separates and by studying the various effluent profiles from dissolver core flooding studies on reservoir sand. The potential damage mechanism include silicate dissolution, fines generation/migration, emulsion formation/stabilization and mechanical strength reduction.
