Lean approach firstly emerged from the lean manufacturing principles applied into the automotive sector shop floor after the World War II. It overtook its barriers and achieve many different industries. Lean concepts and tools also have been used in the service sector. All organizations and companies that have absorbed the lean approach on its flows and process have one goal in common: they look for better efficiency, reducing losses and wastes. At the end, they want to have better profitability when offering your goods or services. Recently, some oil and gas companies also started to experience the benefits of the lean thinking by improving its process, reducing failures, errors, and rework. Today, there are many different lean tools available, but, the value stream mapping (VSM) is still the most fundamental because it provides a wide sight of the processes with its material and information flows. Also, it indicates points of improvement. In this context, the main goal of this research was to evaluate the impact of the value stream mapping tool on the performance indicators (efficiency and profitability) of an oil and gas company key process. Also, this research proposed and executed an action plan to reach the desirable improvements, which were the reduction of wastes and costs for the key process of the Beta company, where the research was applied. To reach this goal, this research was based on a robust literature review that comprised the following themes: the emergence of the Toyota Production System, the principles and evolution of lean thinking, the applicability of the lean thinking in the services sector, the lean thinking applied into oil and gas sector, the value stream mapping (VSM) tool and finally the VSM applied in the oil and gas sector. This review was carried out to raise the reference books and the state of art of these main themes related to this research. The methodology applied in this qualitative research was the action research method. The research has been divided in four phases: exploratory, principal, action, and evaluation. The methodological resources used to collect data were the participant and non-participant observations, besides the documentary research to internal document of the Beta company, where the research was developed. All this data together with the Beta?s employees that were chosen to be part of the central seminar enabled that the current state map of the process ?recertification of customer-owned flowline equipment (REFT)? was carried out. After this, a critical analysis to identify opportunities for improvement and waste reduction was developed together with an action plan to achieve the future state map for this REFT process. After the action plan execution, it was possible to evaluate the efficiency performance indicator, which grown up from 20,62% (in the current state) to 60,37%. Also, the profitability performance indicator grown up from 32,57% to 76,08%. All this math based on the average of the batches of equipment observed and evaluated. This improvement was achieved mainly because of the reduction of the total lead time of the process. This happened because of the reduction of overproduction, transportation, processing, defects, movement, waiting, stock and intellectual wastes and losses.
