... the rotating disk reactor. Additives such as corrosion inhibitors, synthetic polymers, mono and divalent chloride salts, mutual solvent, dissolved iron, viscoelastic surfactants, and chelating agents were investigated. The results showed that more reliable data was obtained at lower acid concentrations...

Paper Number: SPE-175829-MS
... Abstract By increasing worldwide energy demand and reducing reserves, enhanced oil recovery (EOR) from current fields has become more and more important. Moving from polymer to surfactant flooding, Chemical EOR has been considered an expensive method, and field applications have been decreased...
