Abstract
Methods and compositions for inhibiting corrosion of metal surfaces in aggressive fluids, including fluids with high total dissolved solids content. The treatment composition can include a stannous corrosion inhibitor and optionally an additive that enhances the corrosion inhibition properties of the stannous component. The additive may include organic compounds having at least one heteroatom.
