摘要：
Systems and methods for fracturing multiple zones in a wellbore. A first port in a first valve assembly can be opened with a shifting tool. A fluid flows through the first port to fracture a first zone, and the first port can be closed with the shifting tool after the first zone has been fractured. A second port can be opened in a second valve assembly with the shifting tool after the first port has been closed, wherein the second valve assembly is positioned below the first valve assembly. The fluid can flow through the second port to fracture a second zone, and the second port can be closed with the shifting tool after the second zone has been fractured.
