Abstract:
A closing sleeve assembly with a ported sleeve is disclosed. The closing sleeve assembly includes a housing; a port formed in the housing; a sealing surface formed in the housing adjacent to the port; and a closing sleeve configured to move between an open position and a closed position. The closing sleeve includes an uphole portion configured to substantially cover the sealing surface when the closing sleeve is moved to the open position; a port formed in the closing sleeve and configured to substantially overlap with the port formed in the housing when the closing sleeve is in the open position; and a seal configured to engage with the sealing surface to form a fluid and pressure tight seal when the closing sleeve is in the closed position.
