  • Open hole multi-zone single trip completion system
    Patent number: 11649694
    Abstract: A multi-zone single trip open hole completion system includes an outer tubular assembly including an uphole end, a downhole end, an inner tubular assembly, an anchor arranged on the outer tubular assembly, and an anchor setting assembly provided on one of the outer tubular assembly and the inner tubular assembly. The anchor setting assembly is operable to selectively set the anchor. An isolation flow path is in the outer tubular. A flow control system is arranged on the inner tubular assembly. The flow control system selectively blocks flow through the inner tubular assembly. A remotely operated valve is arranged in one of the inner tubular assembly and the outer tubular assembly. The remotely operated valve is operable to close fluid flow through the tubular. An isolation packer is arranged along the outer tubular assembly. Closing the remotely operated valve enables the anchor, and the isolation packer to be set.
