New cementing technologies and techniques have been applied to the challenging task of cementing tiebacks. Cement sheath stress analysis, reverse cementing, ductile cements and delayed-gel slurries are among the technical advances in tieback cementing that have been applied in the Gulf of Mexico (GOM). This article outlines the reasons and methods for cementing tiebacks, and details the most recent technologies in a job performed in Mobile Bay.
