The sealing method comprises the steps of measuring the characteristics of the casing, determining a position of the zone, determining an extent of the zone in a longitudinal direction of the casing, determining a part of the zone and an extent of the part whose casing characteristic when measured is within the predetermined interval, the part extending in the longitudinal direction of the casing, positioning a first liner overlapping the first area of the part of the casing, positioning a second liner overlapping the second area of the part of the casing, expanding the first liner, and expanding the second liner.
