Abstract

THE PRESENT INVENTION PROVIDES SYSTEMS AND METHODS FOR PROTECTING THE LOWER MAIN WELLBORE (122) OF WHIPSTOCKS AND COMPLETION DEFLECTORS FROM DEBRIS ACCUMULATION. A WELL SYSTEM SUBASSEMBLY (102) INCLUDES A DEFLECTOR TOOL (130) ARRANGED WITHIN A CASING STRING (124) AND DEFINING A DEFLECTOR SURFACE (204) AND AN INNER BORE (206) EXTENDING LONGITUDINALLY FROM THE DEFLECTOR SURFACE (204) AND ONE OR MORE SEAL STACKS (216) DISPOSED ABOUT THE INNER BORE (206) OF THE DEFLECTOR TOOL (130). A WELLBORE BARRIER DEVICE (218) IS DISPOSED ABOUT THE INNER BORE (206) UPHOLE FROM THE ONE OR MORE SEAL STACKS (216) AND IS EXPANDABLE FROM AN UNSWELLED CONFIGURATION TO A SWELLED CONFIGURATION. WHEN THE WELLBORE BARRIER DEVICE (218) IS IN THE SWELLED CONFIGURATION, IT PROTECTS THE ONE OR MORE SEAL STACKS (216) FROM DEBRIS GENERATED FROM MILLING AND/OR DRILLING OPERATIONS.
