Purpose Lean approach has overcome the boundaries of the automotive and manufacturing industry and has achieved many different sectors of the economy, including services. In this context, this paper aims to investigate the applicability of value stream mapping (VSM) tool in processes of the oil and gas chain. Also, this paper investigates if there is a specific framework currently being used by organizations belonging to this chain to map the value stream of its processes. Design/methodology/approach A detailed systematic review of the literature is done by using a set of relevant keywords based on peer-reviewed journal articles and conference papers available in the Scopus database, analyzing data from 2012 to 2017. Content analysis methodology involving a four-step process (identification, screening, eligibility and inclusion) suggested by Moher et al. (2009) was adopted for this study. Findings The number of studies in literature on VSM applicability to the oil and gas chain processes is low when compared to studies regarding the application of lean tools and methods in general in this area. Also, there is no specific framework that has been used by the oil and gas chain companies to carry out the VSM, which is a research gap that can be further explored. Research limitations/implications Sample size for this research consists of 42 studies, thereby limiting the generalizability of the research studies. However, the analysis presented in this paper was based only on Scopus database, which is a remarkable and broad base, which provided robustness to the data found. Practical implications Practicing managers of oil and gas chain who are planning to transform their processes can use the VSM for it. Researchers can explore the research gap found in this study and develop a specific framework to implement VSM in the oil and gas chain processes. Originality/value This is the first paper to evaluate the VSM tool applicability to the oil and gas chain processes based on an systematic literature review and understand if this is possible and if there is a specific framework to carry out this task.

Este trabalho tem como objetivo mapear e modelar um processo crítico de uma organização específica do setor de óleo e gás no Brasil em seu estado atual através da técnica BPMN e avaliar possíveis cenários de melhorias, utilizando ferramentas de gestão e de qualidade. Em seguida é modelado um estado futuro para o mesmo processo com a introdução das melhorias sugeridas. A metodologia de pesquisa ação aliada à utilização de suas estratégias de coleta de dados como observação e entrevistas se mostraram adequadas para atingir o propósito deste artigo. O estudo mostra sua relevância ao aplicar ferramentas de gestão de processos em uma organização que até então, não possuía seus processos internos mapeados, e sugere trabalhos futuros para verificação da eficiência e eficácia das melhorias propostas.Palavras-chave: Gestão e melhoria de processos.

In 2017, after a failure of a flexible riser operating in an environment with high level of CO2, a new failure mode of the flexible pipes was reported: Stress Corrosion Cracking induced by CO2(SCC-CO2). This issue was not considered in the design and manufacturing standards of these equipment. In this context, this paper covers a literature of SCC-CO2 phenomenon. Moreover, the impacts on the flexible pipes due to this failure mode are discussed. Lastly, this research focuses on the current technologies and tools used to inspect and access the integrity of the pipes used on gas injection and production lines. The paper is written based on detailed review of the literature. A set of relevant keywords were used on peer-reviewed journal articles and conference papers mainly available in the OnePetro database. Some recognized books, technical specifications and PhD thesis were also consulted. The papers included in this literature review were selected based on four steps: identification, screening, eligibility and inclusion (Moher et al., 2009). This methodology allowed to find out what is the current state of the art about the topics covered in this study. This detailed review of literature revealed that after the issue reported in 2017, the industry invested in the research of the SCC-CO2 phenomenon. Many studies were conducted in order to investigate what are the main factors that triggers this failure mode on the flexible pipes used for the production and gas injection in the deep-water and ultra-deep-water fields with high levels of contaminants and harsh metaocean conditions. Then, different technologies and tools were developed to inspect the flexible pipes. Operators can use this data to estimate the remaining service life of the lines. There are proven tools that can inspect the gas injection pipes using different non-destructive techniques. However, there is still a gap on the inspections of the annular region of the production flexible pipes. This happens due to the limitation of reading through the thermal insulation layer contained on them. This is very critical because the inspection of the pipe annulus detects if it is dry or flooded. This information is vital to assess the integrity of the structural armors of the flexible pipes.
