Abstract: A system and method for fracturing multiple zones along a length of a wellbore during a single run are provided. A single mechanical shifter device may be lowered on coiled tubing to shift open multiple sleeve assemblies set along the wellbore to expose different fracture zones for desired fracturing treatments. The sleeve assemblies may each include a shifting sleeve designed for engagement with the mechanical shifter device. The mechanical shifter device may move the shifting sleeve along the wellbore to collapse a baffle component of the sleeve assembly. Once the baffle is collapsed, an isolation component of the shifter device may engage the collapsed baffle to form a plug through the wellbore. Pressure applied from the surface may push the baffle and a sliding sleeve of the sleeve assembly downward, thereby exposing fracturing ports through the casing of the wellbore. Fracturing applications may then be performed through the ports.

Abstract: A system and method for fracturing multiple zones along a length of a wellbore during a single run are provided. A single magnetic shifter device may be lowered on coiled tubing to shift open multiple sleeve assemblies set along the wellbore to expose different fracture zones for desired fracturing treatments. The sleeve assemblies may each include a magnetic sensing system designed to detect a magnetic field output from the shifter device.
