Evaluation of polyacrylamide gels with accelerator
1. Introduction. With the growth and maturity of oil field worldwide, high water cut is common to see in oil wells. Excessive produced water will restrict oil recovery and cause large economic loss due to the cost of lifting, separating, treating and disposing produced water , , , , .Many chemical techniques such as foam, microgel, emulsified asphalt, polymer gel or combined techniques have

Application of polyacrylamide in oil exploitation -Henan
Application of polyacrylamide in oil exploitation 19/04/09 Application of polyacrylamide in oil exploitation. Polyacrylamide (PAM) can widely use in more area,such as papermaking dispersant, incense making ,oil industry etc.. Here we will make a introduction about pam using in oil industry.
Potassium chloride (KCl) salt has been found to be more effective in the development of inhibitive water based drilling fluid system due to its high shale inhibition capability . Many industries use polyacrylamide to mitigate wellbore instability problems arising due to swelling and dispersion of shale and cuttings inside the wellbore because of its unique property of shale encapsulation.
Properties of Polyacrylamides
Applications. Poly(acrylamide-co-acrylic acid) and its sodium salts (APAM) are widely used as thickening agent, binder, super absorbent, soil conditioner, filtering aid, flocculating agent, crosslinker, suspending agent, lubricant, and oil recovery agent. One of its largest uses is waste water treatment.

Evaluation of hydrophobically associated polyacrylamide
The evaluation of the physicochemical properties of a polymer in solution in many cases permits establishing useful correlations between its prop-erties and performance in a specific application
Polyacrylamide is also used in water, sewage and waste treatment, oil recovery, ore processing paper making, and to make permanent-press fabrics, to synthesize dyes, contact lenses, and in the construction of dams, tunnels and sewers (Habermann 2002). [7] Polyacrylamide is also present in cigarette smoke.

With the rapid growth of energy consumption, enhanced oil recovery (EOR) methods are continually emerging, the most effective and widely used was polymer flooding. However, the shortcomings were gradually exposed. A novel decorated polyacrylamide might be a better alternative than polymer. In this work, the molecular structure and the properties reflecting the viscosity of decorated
In enhanced oil recovery (EOR), the stability of polymeric systems in harsh reservoir conditions is significant. A proof of concept research on the application of supramolecular self-assembly for EOR is presented in this paper. The motivation was to acquire new insights on the effectiveness of these extended polymolecular assemblies with improved salinity and hardness tolerance and
Adsorption of crude oil from aqueous solution by hydrogel
The adsorption of crude oil (initial concentration 0.5–30 g/L) from aqueous solution using hydrogel of chitosan based polyacrylamide (PAM) prepared by radiation induced graft polymerization has been investigated. The prepared hydrogel was characterized by FTIR and SEM micrographs.
The oil recovery from core material and a specifically designed flow cell using novel branched (comblike) polyacrylamides (PAM) has been investigated. The injectivity characteristics of the different branched PAMs were evaluated by filtration tests and core-flow experiments. The number of arms of the branched PAM has little to no effect on the filterability and permeation through a porous medium.
- What is polyacrylamide gel electrophoresis (PAGE)?
- To follow this article, as basic understanding of protein biochemistry is helpful. Polyacrylamide gel electrophoresis (PAGE) is a technique use almost universally in life science laboratories. The goal of this technique is to separate a mixed sample of proteins to identify and quantify single proteins from the mixture.
- What is the difference between agarose gel and polyacrylamide gel electrophoresis?
- In polyacrylamide gel electrophoresis, polyacrylamide gel separates macromolecules, i.e., proteins of size five kDa to 250 kDa. Similarly, it can also isolate DNA of 5- 500 bp size. In agarose gel electrophoresis, agarose gel separates DNA, RNA, and protein. It can isolate DNA about 50-20,000 bp in size.
- Why do we use polyacrylamide instead of agarose?
- In PAGE, rather than agarose, we use a chemical called polyacrylamide. Varying the percentage of polyacrylamide in the gel lets us change the size of the pores in the gel, which means that we can separate different sizes of protein in different percentage gels. Typical gel percentages are shown in the table below.
- Why is polyacrylamide gel electrophoresis useful in HIV testing?
- PAGE is helpful to analyze the size and number of polypeptide subunits. It is useful in HIV tests to separate HIV protein. Polyacrylamide gel electrophoresis consists of the following benefits:
