A single trip liner running and tie-back system includes a liner string to case a formation, a polished bore receptacle installed in a liner hanger, and a tie back casing string to tie back the liner string to a wellhead. The tie back casing string is fit with a seal assembly comprised of a no-go stopper, and the seal assembly of the tie back casing string is anchored inside the polished bore receptacle of the liner hanger to run the liner string and the tie back casing string in tandem.
