Curing lost circulation of water-based drilling muds
In general, in one aspect, embodiments relate to a method that includes circulating a water-based drilling fluid though a drill string to extend a wellbore through a subterranean formation, separating at least a portion of the water-based drilling fluid from the circulated water-based drilling fluid to form a separated portion of water-based drilling fluid, mixing a metal salt and a metal oxide into the separated portion of water-based drilling fluid to form a mixture and shearing the mixture to form a chemical sealing pill, where the chemical sealing pill includes the portion of the water-based drilling fluid, the metal salt, and the metal oxide, and after mixing and shearing, introducing the chemical sealing pill into the drill string as a single mixture and flowing the chemical sealing pill into a lost circulation zone in the subterranean formation.
