Patent ID: 7588077

Claim:
A downhole tubular sealing system, comprising: a deformable tubular sealable to a first tubular and a second tubular thereby capable of effectively sealing an annular space between the first tubular to the second tubular, the deformable tubular comprising: a first deformable portion configured to deform in a first radial direction; a second deformable portion configured to deform in a second radial direction, the second radial direction being opposite to the first radial direction; and a third deformable portion configured to deform in the first radial direction, the second deformable portion being positioned longitudinally between the first deformable portion and the third deformable portion, at least one of the first deformable portion and the third deformable portion being sealable to the first tubular in response to the first deformable portion and the third deformable portion being deformed and the second deformable portion being sealable to the second tubular in response to the second deformable portion being deformed and the first deformable portion, the second deformable portion and the third deformable portion being configured to deform in a sequence.
