(54) Apparatus and methods for running liners in extended reach wells


(57) A method of lining a wellbore includes deploying the liner into the wellbore using a workstring and a setting tool; engaging the setting tool with a casing or liner previously installed in the wellbore; and pressurizing a chamber formed between a seal of the setting tool and a shoe of the liner, thereby driving the liner further into the wellbore, wherein reactionary force is transferred to the previously installed casing or liner by the engaged setting tool.
