ABSTRACT:
A method for resolving sludge/emulsion formed as a result of acidization of oil and gas wells comprising the steps of adding an iron-control chemical in an amount sufficient to prevent the formation of insoluble iron compounds, and adding a water-dispersible emulsion breaker in an amount sufficient to separate the sludge/emulsion into clean oil and water. Further treatment of the waste water with water clarifiers, settling vessels and passing it through a macroreticular resin results in water that is at least less than 29 mg/L total oil and grease for overboard discharges from offshore facilities.
