Barium sulfate problem sometimes occur downstream of alum addition, since alum lowers the pH and also supplies additional sulfate ions. One way to minimize barium sulfate scale is to use polyaluminum chloride in place of the alum. Another way is to acidify the pulp at an earlier, less vulnerable point in the process, perhaps in the first chest ...

Tapered milling bit was replaced with the expandable milling bit which cleared the path. The expandable milling bit closed has 3-1/8" OD, and for this well their maximum opening was limited to 4.1" (tubing ID 4.126"). The WR-SCSSV depth was achieved, this was clearly confirmed on surface by current draw down and milling response.

Barium sulphate scale removal offshore

Barium is difficult to control because a mill cannot avoid this carbonate-to-sulfate transition using common bleaching technology. An advantage in controlling barium scales is that the sulfate, once formed, will not redissolve to any appreciable extent, and this reduces the rate at which barite scale can form in other locations in the bleach plant.
