Tie-back seal assembly
Abstract:
A tie-back seal system is disclosed. The system includes a tie-back seal assembly including an outer sleeve, an inner sleeve disposed within the outer sleeve, a shear pin extending through the outer and inner sleeves, and a ratch-latch pin coupled to and disposed downhole from the inner sleeve. The system also includes a tie-back liner disposed within the inner sleeve and coupled to the outer and inner sleeves using the shear pin such that the shear pin prevents axial movement of the tie-back liner relative to the outer and inner sleeves. The system further includes a tie-back receptacle configured to engage the ratch-latch pin to prevent axial movement of the inner sleeve and tie-back liner in an uphole direction and including a shoulder that, when in contact with the outer sleeve, prevents axial movement of the outer sleeve in a downhole direction.
