摘要： A downhole tool comprising magnesium is placed in a well bore in a subterranean formation for performance of a downhole operation. After performance of the downhole operation, rather than mechanically retrieving or removing the tool, at least a portion of the magnesium in the downhole tool is dissolved by contacting the downhole tool with an aqueous ammonium chloride solution.
