Zusammenfassung:	Compositions and methods for providing water shut off within a water producing zone of a wellbore. The composition includes alkaline nanosilica particles and hydrolysable ester-based 3D engineered non-convex particles. The method includes dissolving the hydrolysable ester-based 3D engineered non-convex particles to release an acid, which reacts with the alkaline nanosilica particles to form a solid.
