A Ball-Activated Sleeve is a mechanical device used in multi-stage hydraulic fracturing of horizontal wells. It allows operators to open specific stages in the wellbore by dropping balls of various sizes into the well. Each ball travels downhole and lands in a matching seat within a sleeve, applying pressure that shifts the sleeve open, allowing fluid to enter the formation for stimulation.
