“…Due to the adjustable cross-linking time and the transition of the polymer solution into the gel, it is possible to place the gel screen at a predetermined distance from the injection well in such a way that, by changing the direction of the water flow, it leads to the displacement of oil from the bypassed parts of the reservoir (Figure 17). Trivalent metal salts act as cross-linkers in this technology: when they interact with the carboxyl group of the polymer, a cross-linked spatial structure is formed that prevents water filtration [83] (Figure 18).

The use of gels in oil production processes has become a regular practice in oilfield operations and is constantly developing in all oil-producing countries of the world, as evidenced by the growth of publications and patent activity on this topic. Many oil production processes, such as hydraulic fracturing, conformance control, water, and gas shutoff, cannot be imagined without the use of gel technologies. Inorganic, organic, and hybrid gels are used, as well as foams, gel-forming, and gel-dispersed systems. The possibility of a broad control of structural and mechanical properties, thermal stability, and shear resistance by introducing microscale and nanoscale additives made hydrogels and hydrocarbon-based gels indispensable tools for oil engineers.

“…Studies have shown that viscoelastic systems capable of generating normal stresses are one of the most effective buffer systems for cementing, since they are able to displace drilling fluid even from pinched zones [3,4]. However, it remains a challenge to design the compositions of these systems without detailed knowledge of their behaviour under various loads.…”

The object of research in this study is viscoelastic systems used as spacer systems in well casing during drilling. Polymer network-metal ion systems display distinctive properties, facilitating effective well coverage through their normal stresses. The primary problem addressed in this research was optimizing viscoelastic system composition for well casing. Researchers sought the ideal sodium dichromate concentration to maximize viscosity in polyacrylamide-based spacer fluids. This optimization is crucial for enhancing casing cementing quality, especially in challenging geological conditions. Utilizing a precise HAAKE MARS III rheometer, various tests, including shear, oscillatory, frequency, creep, and recovery tests, were performed to assess viscoelastic system rheology. Obtained results of optimal deformation interval for a solution with sodium bichromate is 40 Pa and aluminum sulfate, the yield strength was equal to 110 Pa. This research optimized cross-linker concentration, increasing spacer system viscosity. This enhancement improves well cementing efficiency and allows for operation in challenging geological conditions. The precise rheometer unveiled previously unexplored rheological characteristics. The optimized viscoelastic spacer fluid is invaluable in well casing, especially in challenging geological settings. This research guides the design of process fluids, enhancing casing cementing quality, and improving drilling efficiency and safety. Engineers and researchers can leverage the rheological data for informed decisions and better field performance
