Abstract
Processes and compositions to control inorganic sulfide scale formations in oilfield applications, including flow lines, wellbores, and subterranean formations. One example involves providing a treatment fluid comprising: a base fluid, a scale inhibitor, and a water clarifying agent; introducing the treatment fluid into a target region, wherein an inorganic cation and a sulfide anion are present in the target region; allowing the inorganic cation and the sulfide anion to form a sulfide precipitate; and using the treatment fluid to remove at least a portion of the sulfide precipitate from the target region.
