Polymeric Nanoparticles Synthesized for EOR Applications
TEHRAN, April 24 (FNA)- Researchers at Iran's Research Institute of Petroleum Industry (RIPI) reported the synthesis of a polymeric nanoparticle with practical applications in oil extraction and EOR methods.
"Polyacrylamide and its copolymers are well known for their services in oil industries such as in drilling muds and extracting fluids and EOR technologies," Mehdi Abdollahi, faculty member of RIPI at polymer science and technology division, told to the news service of INIC, adding, "It is about decades that such polymer compounds have been used as ingredients in formulation of aqueous-type drilling for fluids to control rheological properties, minimize fluid loss and stabilize water-sensitive shales."
"In this research, acrylamide-based latexes and polymeric nanoparticles with molecular weights exceeding one million grams per mole and dimensions less than 200 nm were yielded. The synthesized materials possessed a size distribution ranging from 50 to 400 nm," Abdollahi stated.
"We have performed a comprehensive study on many influential parameters, including impeller type and its rotational speed, temperature, concentration of the initiator, emulsifier concentration and its hydrophilic-lipophilic balance and polymerization reaction kinetics," he added.
"Our experimental revealed that the greatest molecular weight (8 million grams per mole, approximately) corresponds to the case with Azobis (isobutyronitrile) as the initiator."
Concluding his views on the research, Abdollahi referred to the controllability over particle sizes (from nano to micro scale) and the large molecular weight of the synthesized compounds as the salient point of their approach.
