Recent development of enhanced oil recovery in China
Recent development of enhanced oil recovery in China. which have been used for oil production of industrial scale based on numerous pilot tests. We have developed a biopolymer (Xanthan gum) which can be used under the conditions of high temperature (80°C) and high salt concentrations (170 000 ppm). The polyacrylamide polymer is used in
The oil production increases with the microscopic sweep of the reservoir and the displacement efficiency of the oil . Indeed, the use of water-soluble polymers improves the water–oil mobility ratio , and leads to enhanced oil recovery. However, given the harsh conditions present in most oil reservoirs, new problems and limitations arise
Nanoparticle modified polyacrylamide for enhanced oil
Silicon dioxide (SiO 2) nanoparticles (NPs) have been recently proposed to increase the performance of polyacrylamide (PAM) for enhanced oil recovery (EOR) applications.However, SiO 2 /PAM nanocomposites tend to agglomerate or even desposit under harsh conditions such as high temperature-high salinity (HT-HS), which greatly decreases the potential for future field applications.
flooding and gel treatment agent in enhanced oil recovery. Recent developments, performance, applications and limitations of polyacrylamides and its derivatives, including copolymers and hydrogels for enhancing oil recovery are reviewed. A water-free suspension system was developed to synthesize PAMs and PAMs-microgel.
Polymers for Enhanced Oil Recovery - BASF
Standard hydrolyzed polyacrylamide (HPAM) is the most widely used polymer in enhanced oil recovery applications. HPAM can be obtained either by post hydrolysis of acrylamide homopoly-mers or by copolymerization of acrylamide and sodium acry-late. Advantages and disadvantages of the different products are summarized here.

In either case, the molar fraction of the acrylate moiety is referred to as the degree of hydrolysis (t), and is typically between 0.15 and 0.40 for commercial hydrolyzed polyacrylamide (HPAM) polymers used for enhanced oil recovery. During its residence in the reservoir at elevated temperature and/or pH, t of polyacrylamide polymers increases.
