“…Thus, the addition of a high concentration of silica nanoparticles can be a good option for reservoirs with high temperatures. Haruna et al (2020) studied the effects of the incorporation of nanoparticles on the rheological properties, thermal stability and degradation of PAM solutions under HTHS conditions. For this, silica nanoparticles and SiO 2 nanoparticles modified with (3-aminopropyl) triethoxysilane (MSiO 2 ) were used, forming the hybrid nanosystems SiO 2 /PAM and MSiO 2 /PAM, respectively.…”

Due to the growing demand for oil and the large number of mature oil fields, Enhanced Oil Recovery (EOR) techniques are increasingly used to increase the oil recovery factor. Among the chemical methods, the use of polymers stands out to increase the viscosity of the injection fluid and harmonize the advance of this fluid in the reservoir to provide greater sweep efficiency. Synthetic polymers based on acrylamide are widely used for EOR, with Partially Hydrolyzed Polyacrylamide (PHPA) being used the most. However, this polymer has low stability under harsh reservoir conditions (High Temperature and Salinity – HTHS). In order to improve the sweep efficiency of polymeric fluids under these conditions, Hydrophobically Modified Associative Polymers (HMAPs) and Thermo-Viscosifying Polymers (TVPs) are being developed. HMAPs contain small amounts of hydrophobic groups in their water-soluble polymeric chains, and above the Critical Association Concentration (CAC), form hydrophobic microdomains that increase the viscosity of the polymer solution. TVPs contain blocks or thermosensitive grafts that self-assemble and form microdomains, substantially increasing the solution’s viscosity. The performance of these systems is strongly influenced by the chemical group inserted in their structures, polymer concentration, salinity and temperature, among other factors. Furthermore, the application of nanoparticles is being investigated to improve the performance of injection polymers applied in EOR. In general, these systems have excellent thermal stability and salinity tolerance along with high viscosity, and therefore increase the oil recovery factor. Thus, these systems can be considered promising agents for enhanced oil recovery applications under harsh conditions, such as high salinity and temperature. Moreover, stands out the use of genetic programming and artificial intelligence to estimate important parameters for reservoir engineering, process improvement, and optimize polymer flooding in enhanced oil recovery.

“…1 The most commonly used polymers are polyacrylamide and partially hydrolysed polyacrylamide polymers. 2,3 Although these polymers have a certain effect of oil displacement, they undergo thermal degradation, and hydrolysis at high temperatures. As a result, the stability of the polymer is reduced and the macroscopic in-depth profile control ability is deteriorated.…”

Engineering functional materials from biomass and industrial waste is of great significance for sustainable chemistry and engineering. Bio-based poly (acrylic acid-acrylamide-biomass-fly ash) (PAABF) composites with appropriate densities were designed. Graft copolymer composites were prepared for the first time by combining biomass and fly ash as graft materials with acrylic acid and acrylamide as monomers. The results showed that PAABF composites have a three-dimensional network structure. Cellulosic biomass (sodium carbo-xymethyl cellulose, cattail cellulose) and fly ash improved the thermal stability, water absorption, water retention, temperature resistance, and salt resistance of the composites. PAABF composites can be used as water plugging profile control agent for oilfield with high-salinity and deep burial.

The new initiator of the polymerization of acrylamide, leading to the formation of crosslinked polyacrylamide, was discovered. The structure of the synthesized polyacrylamide was characterized by XRD, 1Н NMR, and 13С NMR spectroscopy. It was shown that 1,3-dimethylimidazolium (phosphonooxy-)oligosulphanide is able to initiate radical polymerization under drying aqueous solutions of acrylamide, even at room temperature. According to XRF data, the synthesized polyacrylamide gel contains 0.28 wt% of sulphur. The formed polymer network has a low crosslinking density and a high equilibrium degree of swelling. The swelling rate of polyacrylamide gel in water corresponds to the first order kinetic equation with the rate constant 6.2 × 10−2 min−1. The initiator is promising for combining acrylamide polymerization with the processes of gel molding and drying.
