Polymer gels have been designed and successfully applied to improve sweep efficiency and to reduce excessive water production by minimizing reservoir heterogeneity. Based on their compositions and application conditions, polyacrylamide polymer gels can be classified into three types: in-situ monomer-based gel, in-situ polymer-based gels and preformed particle gels.

Review of recent advances in - Polymer Bulletin
Several crosslinked polymer gels have been developed over the last 5 decades to address the different technical challenges in oil reservoirs especially conformance control operations. Among these systems, polyethylenimine (PEI) crosslinked polymer gels, which have gained a huge interest thanks to their eco-friendly aspect and thermal stability at extremely high temperatures.
O.E. Philippova, A.R. Khokhlov, in Polymer Science: A Comprehensive Reference, 2012. 1.13.2 Synthesis of Polymer Gels. There are two ways to synthesize the polymer gels: from monomers and from polymers.In the first case the network structure is formed simultaneously with the synthesis of polymer chains; in the second case the network is obtained by cross-linking of already existing polymer chains.
Polymer Gel Systems for Water Management in High
Polymer gel systems as water management materials have been widely used in recent years for enhanced oil recovery applications. However, most polymer gel systems are limited in their ability to withstand the harsh environments of high temperature and high salinity. Those polymer gel systems that can handle high-temperature excessive water treatments are reviewed in this paper and categorized
2. Polymer gel dosimetry methodology. Polymer gel dosimetry involves three steps (figure 1): first, the radiation sensitive polymer gel is fabricated and poured into an antropomorphically shaped container and associated calibration vials, and left to set.Second, the antropomorphic phantom and associated vials are irradiated.
Time-Resolved Raman and Polyacrylamide Gel Electrophoresis
The bacterial RNA polymerase (RNAP) elongation complex (EC) is highly stable and is able to extend an RNA chain for thousands of nucleotides. Understanding the processive mechanism of nucleotide addition requires detailed structural and temporal data for the EC reaction. Here, a time-resolved Raman spectroscopic analysis is combined with polyacrylamide gel electrophoresis (PAGE) to monitor
Two polyacrylamide gels (PAGs) of identical composition were irradiated with the same four arc stereotactic treatment to maximum doses of 15 Gy (PAG1) and 8 Gy (PAG2). The PAGs were CT imaged using a previously defined protocol that involves image averaging and background subtraction to improve image quality.

For gels of flexible polymers such as polyacrylamide, G′ is a constant for strain values up to 100%: The flexible polymer responds linearly. In contrast, gels of actin, fibrin, and collagen show strain stiffening behavior at medium strain levels, i.e., the G ′ of these gels becomes larger at larger strains.
