A separate, identifiable barrier manual should be agreed upon and used by licensees, rig operators, and cementing contractors. These manuals should set out best industry practice in relation to achieving and maintaining well integrity. They should describe barrier types, barrier standards, general principles of well integrity, testing and verification methods and technologies, standard operating procedures (including procedures for the capture and communication of relevant information within and between relevant stakeholder entities). Barrier manuals should address blowout control during drilling, completion, re‐entry, tie‐back of casing strings and so on. Barrier manuals should be the subject of expert external review, and should be regularly updated.
