  • Hydrofluoric acidizing compositions for subsea riser systems and modulating agent for hydrofluoric acidizing composition
    Patent number: 10005952
    Abstract: Compositions and methods for formulating acidizing treatment fluids comprising hydrofluoric acid are provided. In one embodiment, the method comprises: providing a treatment fluid comprising: an aqueous base fluid; at least one chelant; hydrofluoric acid; and at least one corrosion inhibitor; pumping the treatment fluid through a subsea riser system; and introducing the treatment fluid into a subterranean formation. In another embodiment, the method comprises: providing a treatment fluid comprising: an aqueous base; at least one chelant; hydrofluoric acid; and at least one corrosion inhibitor; and a boron-containing compound; and introducing the treatment fluid into a subterranean formation via a wellbore penetrating at least a portion of the subterranean formation.
