Formation Damage due to Iron Precipitation in Acidizing Operations and Evaluating GLDA as a Chelating Agent
Iron control during acidizing plays a key role in the success of matrix treatment. Ferric ion precipitates in the formation once the acid is spent and the pH exceeds 1-2. Precipitation of iron (III) within the formation can cause formation damage. Chelating agents such as EDTA and NTA are usually ad...
