Abstract (en)
A method of abandoning a well includes the steps of: assembling a tool string (12) including a perforating gun (14) interconnected between first and second packer assemblies (24, 26); conveying the tool string (12) into a wellbore (20) in a single trip into the wellbore (20); setting the first packer assembly (24); setting the second packer assembly (26); firing the perforating gun (14); and flowing cement into an annulus longitudinally between the first and second packer assemblies (24, 26). A system for abandoning a well includes a tool string (12) configured for conveyance into a wellbore (20) in a single trip into the wellbore, the tool string (12) including a perforating gun (14) interconnected between first and second packer assemblies (24, 26), each of the first and second packer assemblies (24, 26) including a permanent packer.
