This Technical Specification is intended to give req
39、uirements and information to the Well Operator on managing well integrity for the operational phase. Furthermore, this Technical Specification addresses the minimum compliance requirements for the Well Operator, in order to claim conformity with this Technical Specification.It is necessary that user
40、s of this Technical Specification are aware that requirements above those outlined in this Technical Specification can be needed for individual applications. This Technical Specification is not intended to inhibit or replace legal requirements; it is in addition to the legal requirements; where ther
41、e is a conflict the legal requirement always takes precedence. This can be particularly applicable where there is innovative or developing technology, with changes in field or well design operating philosophy.This Technical Specification addresses the process of managing well integrity by assuring c
42、ompliance to the specified operating limits for identified well types, that are defined based on exposure of risk to people, environment, assets and reputation, supported by associated well maintenance/monitoring plans, technical reviews and management of change.The following terminology is used in
43、this Technical Specification.a) The term “shall” or “must” denotes a minimum requirement in order to conform to this Technical Specification.b) The term “should” denotes a recommendation or that which is advised but not required in order to conform to this Technical Specification.c) The term “may” i
44、s used to indicate a course of action permissible within the limits of the document.d) The term “consider” is used to indicate a suggestion or to advise.e) The term “can” is used to express possibility or capability.

Users should therefore consider printing this document using a colour printer.1 ScopeThis Technical Specification pro
46、vides requirements and methods to the oil and gas industry to manage well integrity during the well operational phase.The operational phase is considered to extend from handover of the well after construction, to handover prior to abandonment. This represents only the period during the life cycle of
47、 the well when it is being operated and is illustrated in Figure 1.The scope of the Technical Specification includes: A description of the processes required to assess and manage risk within a defined framework. The risk assessment process also applies when deviating from this Technical Specificatio
48、n. The process of managing well integrity by operating wells in compliance with operating limits for all well types that are defined based on exposure of risk to people, environment, assets and reputation. The management of well integrity is supported by associated maintenance/monitoring plans, tech
49、nical reviews and the management of change. The assessment of existing assets (wells / fields) in order to start the process of Well Integrity Management in accordance with this technical specification. The handover process required when changing from one activity to another during the operational phase.The scope of the Technical Specification applies to all wells that are utilized by the oil and gas industry, regardless of their age, type or location.The scope of the Technical Specification does NOT apply to: The periods during well
