Partially hydrolyzed polyacrylamide: enhanced oil recovery applications, oil-field produced water pollution, and possible solutions - Springer

Abstract Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

And then, cationic DAC monomers adsorbed on the template agent would rapidly polymerize with adjacent DAC monomers under the effect of initiator radicals in the process of MV-TP. Subsequently, these formed microblock structure precursors would be uniformly inserted, assembled, initiated, and copolymerized with AM to produce the microblock structure under the action of microwave.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

An overview of chemical enhanced oil recovery: recent advances and prospects | International Nano Letters - Springer

Despite the progress made on renewable energy, oil and gas remains the world¡¯s primary energy source. Meanwhile, large amounts of oil deposits remain unrecovered after application of traditional oil recovery methods. Chemical enhanced oil recovery (EOR) has been adjudged as an efficient oil recovery technique to recover bypassed oil and residual oil trapped in the reservoir. This EOR method

Polymers | Free Full-Text | Can Supramolecular Polymers Become Another Material Choice for Polymer Flooding to Enhance Oil Recovery?

High molecular polymers have been widely studied and applied in the field of enhanced oil recovery (EOR). At present, the focus of research has been changed to the design of polymer networks with unique properties such as anti-temperature and anti-salinity, good injection and so on. Supramolecular polymers have high viscoelasticity as well as excellent temperature, salt resistance and

Petroleum Engineer's Guide to Oil Field Chemicals and Fluids

Abstract. This chapter deals with the issues of enhanced oil recovery (EOR) and special chemicals used for this purpose. Approximately 60-70% of the oil in place cannot be produced by conventional methods. EOR methods are gaining importance, in particular with respect to the limited worldwide resources of crude oil.

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.
