      Enhanced Oil Recovery (EOR) | Industrial Engineering

      Enhanced oil recovery (EOR) or tertiary recovery, is the process of extracting oil from an oil field or a reserve that would otherwise be inaccessible using conventional production technology. EOR techniques extract greater volumes from a reserve by altering the oil’s physical properties (i.e. viscosity/density).
