Description
Summary:A bibliographic review of research works dealing with gels based on synthetic polymers and their application in water control under harsh conditions was compiled. The extreme conditions were defined to be above 100 °C with 100 000 ppm of total dissolved solids, including divalent ions. Works describing laboratory experiments and oilfield implementations were also considered. According to current literature, some gels based on synthetic polymers have displayed desirable properties for water control, but in many cases, research is still at laboratory level. Therefore, further studies are required to understand the mode of action and stability of gels and polymers submitted to hard conditions in order to produce high‐performance prototypes. Dispersed particle gels and in‐situ bulk gels based on organic crosslinked polymers are effective systems for water control in the area near the oil well under high temperature and salinity conditions. Sulfonated polymers or polymers with ionic liquids are more promising compared to thermoviscosifying polymers to be used as a base to form gels stable under harsh conditions.
