    EOR Produced Water Recycling Sustainable Development

    Enhanced oil recovery (EOR) is a low cost technique to increase extraction of residual crude oil from an existing oil field. This is accomplished by water flooding where water is injected into the reservoir to “sweep” oil towards a production well. Polymers can also be added to the injection water, “polymer flooding,” to increase the []
