US Patent for Smart polymer flooding process Patent
Design and preparation of a smart system, including a hydrophilic polymer nanoparticle as a core material and a hydrophilic-hydrophobic block copolymer as a coating nanolayer for use in a smart core-shell nanostructure flooding during enhanced oil recovery (EOR) process. The hydrophilic polymers are prepared by an inverse emulsion method. The central core of this nanostructure includes
Water soluble polymers, such as polyacrylamide, partially hydrolyzed polyacrylamide, and thermoviscosifying polymer with polyacrylamide main chains, have been widely used in enhanced oil recovery (EOR) approaches to increase the viscosity of injected water, which increases sweep efficiency due to the aforesaid improved mobility ratio.
Recent Advances in Nanoparticles Enhanced Oil Recovery
Chemically enhanced oil recovery methods are utilized to increase the oil recovery by improving the mobility ratio, altering the wettability, and/or lowering the interfacial tension between water and oil. Surfactants and polymers have been used for this purpose for the last few decades. Recently, nanoparticles have attracted the attention due

- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
