Rotatable valve for downhole completions and method of using same
Abstract:
Method and apparatus for performing a series of downhole operations. The method can include conveying a work string with an integrated valve into a wellbore. As the work string with the integrated valve is conveyed into the wellbore, the valve can be in a first operation mode. When the valve is located within the wellbore, the valve can be adjusted to a different operation mode by selectively rotating at least a portion of the valve without longitudinal movement of the valve relative to the wellbore.
