Scale Deposition and Corrosion have become a nightmare for any oil and gas operations. The antiscalant properties of the green algal (Ulva compressa) and the red algal (Pterocladiella capillacea) extracts were studied using conductivity, electrochemical impedance spectroscopy (EIS), and chronoamperometry techniques in conjunction with microscopic and infrared examinations. The Corrosion inhibitive characteristics were investigated using EIS and potentiodynamic polarization measurements. Mineral scales were deposited from the brine solution by cathodic polarization of the steel surface at −0.9 V (vs. SCE). Potentiodynamic polarization curves indicated that the green algal (U. compressa) and the red algal (P. capillacea) extracts inhibit the Corrosion of steel by controlling the cathodic oxygen reduction process.
