A system and method for hydraulic fracturing including mixing seawater with an additive to precipitate sulfate from the seawater and mixing a flocculating agent with the seawater to agglomerate the sulfate precipitates.

Treating seawater for hydrocarbon production

A low-corrosivity composition suitable for dissolving scale on metals. The scale includes iron sulfide scale. The composition includes an aqueous hydrogen peroxide solution comprising hydrogen peroxide; and an acidic solution comprising at least one acid, where the hydrogen peroxide and acid are present at concentrations such that the hydrogen peroxide does not break down to form visible bubbles at about room temperature, where the hydrogen peroxide and acid are present at concentrations such that iron sulfide scale is removed from a metal with iron sulfide scale, after the composition contacts the metal and iron sulfide scale at an elevated temperature greater than room temperature, and where the hydrogen peroxide and acid are present at concentrations such that pitting is not caused on the metal, the metal comprising carbon steel.
