Hydrogels have the ability to swell significantly, increasing their mass by up to 100 times. This exceptional property makes them valuable in various fields, including agriculture, medicine, industry, and pharmaceuticals. One of the most promising applications of hydrogels is in the oil industry, where a key challenge in oil extraction is finding effective blocking agents to reduce water inflow in oil channels.
This study explores the synthesis of hydrogels via free-radical polymerization of acrylamide and sodium acrylate, with the addition of bentonite to enhance their mechanical properties. The research examines the swelling behavior of hydrogels in relation to monomer concentration, as well as their swelling capacity in sodium chloride solutions. The findings suggest that hydrogel particles can be effectively used to mitigate water production in oil wells.
