Nowadays, oil and gas (O&G) fields are maturing and creating new threats. This urged the operating companies and industry researchers to have intensive focus on well integrity (WI). Building Well Integrity Management System (WIMS) establishes standardized criteria to guarantee that integrity of all wells is preserved during their lifespan, functions properly in healthy condition, and is able to operate consistently to fulfill the expected production/injection demands. Moreover, exploration and production (E&P) companies put Health, Safety, and Environment (HSE), assets, production, local and public image as top priority in their businesses. Having effective WIMS at all times and throughout all well phases reduces the frequency of major integrity failures and thus helps companies to be on track regarding the aforementioned considerations. In this paper, we present a comprehensive review on the system structure and maturity of WIMS in mature fields. This state-of-the-art review highlights the efforts made by different O&G operators all over the world to develop and start application of WIMS, which varies widely due to differences in the main WI challenges that are recurring in each field or concession. Moreover, it lists the goals and expounds the stages of launching effective WIMS. In addition, the key elements, around which the WI program is structured, are discussed and presented for various O&G operators. The major five elements of accountability and responsibility, well operations procedures, well intervention procedures, tubing and casing integrity program, and wellhead and X-tree maintenance are overviewed. Furthermore, this paper assesses WIMS sustainability through demonstration of WI maturity models, scrutiny of maturity levels, and analysis of transformative elements to convert WIMS into strategic framework. Risk management systems as well as application of analytics in WIMS are also covered and thoroughly discussed. In reviewing the literature covering different assets—all over the world for the last 15 years—it was found that real progress was made in WI area, and WIMS established in many operating companies through different approaches. However, the introduced systems lack universality and few of them are applying artificial intelligence as powerful tool for boosting the system. The most obvious finding to emerge from the analysis is that WIMS is crucial system that must be implemented and matured for well lifecycle. The findings of this study can help operating companies for better framing of key pillars to have robust and operable WIMS throughout different fields and concessions, hence improving the well integrity performance worldwide.

如今，石油和天然气（O＆G）领域日趋成熟并带来新的威胁。这敦促运营公司和行业研究人员更加关注井的完整性（WI）。建筑井完整性管理系统（WIMS）建立了标准化的标准，以确保所有井的完整性在其使用寿命内得以保持，在健康状况下能够正常运行，并且能够一致地运行以满足预期的生产/注入需求。此外，勘探与生产（E＆P）公司将健康，安全与环境（HSE），资产，生产，本地和公众形象作为其业务的重中之重。在任何时候，以及在所有油井阶段都拥有有效的WIMS，可以减少重大完整性故障的频率，从而帮助公司按上述考虑进行跟踪。在本文中，我们对WIMS在成熟领域的系统结构和成熟度进行了全面的综述。这项最新的综述着重介绍了世界各地不同的O＆G运营商为开发和开始WIMS所做的努力，由于每个领域或特许权上出现的主要WI挑战的差异，差异很大。此外，它列出了目标并阐述了启动有效WIMS的阶段。此外，还为各种O＆G运营商讨论并介绍了WI程序所围绕的关键要素。概述了责任和责任，井操作程序，井干预程序，油管和套管完整性程序以及井口和X井维护的主要五个要素。此外，本文通过演示WI成熟度模型，审查成熟度级别以及分析将WIMS转换为战略框架的变革要素，评估了WIMS的可持续性。风险管理系统以及分析在WIMS中的应用也将进行讨论。在回顾涵盖过去15年世界各地不同资产的文献时，发现WI领域取得了真正的进展，WIMS通过不同的方法在许多运营公司中建立了WIMS。但是，引入的系统缺乏通用性，很少有系统将人工智能作为增强系统的强大工具。从分析中得出的最明显发现是，WIMS是至关重要的系统，必须实施并使其成熟才能延长油井的生命周期。
