Cigarette Butts Water Extracts as Corrosion Inhibitor in Oil Field Acidizing Fracture Using Different Metal Chlorides Intensifiers

The corrosion inhibitive effect of four metal chlorides (CoCl2, NiCl2, CrCl2 and CuCl2) intensifiers in cigarette butts extracts are contrasted in 15% (wt%) hydrochloric acid with N80 steel at 90 °C. Weight loss, polarization, impedance, electrochemical noise and scanning electron microscopy results are all shown that the most corrosion inhibitive effect of inhibitors is CuCl2 intensifiers, the next is CrCl2, NiCl2 and CoCl2, and the last is cigarette butts extracts. The corrosion inhibitive efficiency of CuCl2 intensifiers can reach 94.2% with the addition of 5% (wt%) and the four metal chlorides all do their intensive job.
