Polymer enhanced oil recovery
 Sebagai Solusi …)
WebEnhanced oil recovery (EOR), also known as tertiary recovery, is used to further produce oil after the primary and secondary phases of reservoir production. According to the US Department of Energy, enhanced oil recovery can extract 40-60% of the original oil in place, which is a substantial improvement over the 10% from primary recovery and 20-40% in … The economic feasibility of the recovery is very important in the petroleum industry. Thus, the cost of the polymer is a major factor due to its large-scale input. Other factors like costs of chemicals, prices of oil, taxation, capital investment, and biocide usage also affect the overall economics of the polymer flooding … See more Linkage of monomer units plays a determining role in showcasing polymer properties.
