    What kind of scale dissolvers can be bullhead to avoid expensive rigless HPCT scale cleanout interventions in wells drilled in carbonate formation?

    James,  do you know the composition of the scale you think has formed?  (carbonate, calcium/barium/strontium sulphate, iron sulphide scales all have different solubility in acids, chelants and other solvents so knowing the scale type and thickness of the deposits are critical to make an dissolver recommendation.  Regards Myles
