Patent ID: 11396789

Abstract:
A system and a method for isolating pressure in a wellbore are described. The system includes a body, a first packer, a second packer, and a control assembly. The body couples to a wellhead and casing. The first packer is disposed within the body and fluidically seals the wellbore providing a first sealing boundary. The second packer is disposed within the body above the first packer to fluidically seal the first packer from the atmosphere providing a second sealing boundary. The first packer and the second packer are spatially arranged within the body to define a packer cavity. The control assembly senses a wellbore pressure on a bottom surface of the first packer, senses a packer cavity pressure, and compares the wellbore pressure to the packer cavity pressure to determine that the wellbore is fluidically sealed from the packer cavity.
