Synthesis Techniques for Polymers Applied to Enhanced Oil Recovery
ثبت نشده
چکیده
The use of water soluble polymers for enhanced oil recovery (EOR) provides an additional chance to extract between 5 to 30% of total oil in place from drilled and mature reservoirs [1]. A big number of patents, mainly from multinational companies, remark the importance of polymers for EOR [2]. The role of the polymer in the aqueous solution is to increase the viscosity of the displacement solution [3]. An important parameter to evaluate the polymer flooding efficiency is the mobility index (M) that depends on the relative permeability and the viscosity of each phase; such parameter between the oil and aqueous phases must be close to the unity to obtain high displacement efficiency [1].

To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of the key factors which can affect fluid displacement during the process of CWI greatly. Therefo...
