Abstract:
Scale remediation at or around a downhole safety valve (DSV), including the volume of a wellbore in a subterranean formation above the DSV. Wellbore fluid is displaced using a gas, the DSV is closed, the gas is released, and a treatment fluid comprises a base fluid and a scale-removal agent is allowed to react with scale in the volume of the wellbore above the DSV.
