  • System and method for fluid diversion and fluid isolation
    Patent number: 8739873
    Abstract: A method of cementing a wellbore, comprising delivering a diversion and movable isolation tool into the wellbore and thereby at least partially isolating a first wellbore volume from a second wellbore volume, the second wellbore volume being uphole relative to the first wellbore volume, passing fluid through the diversion and movable isolation tool into the first wellbore volume, substantially discontinuing the passing of fluid through the diversion and movable isolation tool into the first wellbore volume, passing fluid through the diversion and movable isolation tool into the second wellbore volume. A diversion and movable isolation tool for a wellbore, comprising a body comprising selectively actuated radial flow ports, and a fluid isolation assembly, comprising one or more segments, each segment comprising a central ring and at least one tab extending from the central ring.
