...)acetic acid. It is also possible that carbon dioxide may be present in the evolved gas from exhaustive oxidation of the polymer. Extensive analyses were carried out to determine the ultimate fate of carbon and sulphur in the oxidative digestion of this polymer. Analysis of Digested Amorphous Polymeric...

...). Amphoteric FRs are polymerized with both anionic and cationic monomers. FRs are generally applied as an invert emulsion, slurry, or dry polymers. A liquid invert emulsified polyacrylamide (ePAM) FR is a form in which the FR polymer is present in water droplets that are emulsified into an external oil...

...Introduction Since the early 1960s there has been considerable interest in the use of viscosifiying polymers to Enhance Oil Recovery (EOR) ( Pye, 1964 ; Sandiford, 1964 ; Standnes & Skjevrak, 2014 ) with large scale projects currently underway in the North Sea ( Poulsen et al., 2018...

... Abstract Cr 3+ polymer gel flooding technology is very important for enhancing oil recovery and its field trails have obtained significantly oil increment effect. However, its laboratory physical simulation experiments are rarely carried out according to real reservoir conditions. Therefore...

... and increases the cost of operation. Although several polymeric materials have been employed to improve tensile properties of the cement, these additives have also adversely affected the compressive strength of the cement. A highly stable polymeric additive, triazine-based polymers, is designed, synthesized...

... Abstract Friction reducers (FRs) are essential additives for water used in hydraulic fracturing treatments for shale reservoirs. These polymers swell and unfurl in the frac water so that polymer chains align along the direction of flow to inhibit turbulence thereby reducing friction at high...
