Abstract:
A method of lining a wellbore having a tubular string cemented therein includes: running a liner string into the wellbore using a workstring having a liner deployment assembly (LDA) latched to the liner string; hanging the liner string from the tubular string and setting a seal of the liner string against the tubular string; opening a crossover valve of the liner string located below the set seal; and pumping cement slurry through the open crossover valve and down an annulus formed between the liner string and the wellbore.
