FRACTURING SLEEVES AND RELATED SYSTEMS FOR MULTI-STAGE HYDRAULIC FRACTURING COMPLETIONS OPERATIONS

摘要

A fracturing sleeve for fracturing a subterranean formation can include a wall that forms a cavity and has multiple wall fracturing ports. The fracturing sleeve can also include: a mandrel movably disposed within the cavity, where the mandrel has multiple mandrel fracturing ports; a ball seat assembly (BSA) disposed with the cavity and coupled to the mandrel; a magnetometer sensor configured to measure a magnetic field; and a controller. The controller is configured to: receive a measurement value of the magnetic field from the magnetometer sensor; determine that the measurement value meets a threshold condition; operate the BSA into a closed BSA position to receive a frac ball, causing the mandrel to move from a first closed position to an open position; and release, after a period of time, the mandrel so that the mandrel moves from the open position to a second closed position.
