Estimating the term…
A method, wellbore, and pill for treating a region of a subterranean formation adjacent a wellbore zone of the wellbore, including injecting a gellable treatment composition (e.g., as the pill) through the wellbore zone into the region of the subterranean formation adjacent the wellbore zone, allowing the gellable treatment composition to form nanoparticles in-situ in the region and gel in the region via heat provided by the region to prevent or reduce flow of an unwanted fluid from the region into the wellbore zone. The gellable treatment composition may include a zwitterionic gemini surfactant (ZGS).
1-11. (canceled)
A wellbore in a subterranean formation, the wellbore comprising a wellbore zone having a gel that restricts flow of fluid from the subterranean formation into the wellbore at the wellbore zone, wherein the gel comprises zwitterionic gemini surfactant and silica nanoparticles, wherein the silica nanoparticles are formed in situ from orthosilicate catalyzed by an acid.
A pill comprising
