Petrobras created a corporate program designed to guide and implement Digital Integrated Field Management among its production assets, named GeDIg. Fazenda Alegre field (FAL) was chosen as the EspÍrito Santo Business Unit pilot. The FAL field is an onshore brownfield which produces naphthenic heavy oil from 59 wells with cycled steam injection as improved oil recovery (IOR) method. Management and technical teams from FAL are geographically dispersed among three different locations: its logistics base in São Mateus city, its business unit headquarters in Vitoria city and FAL facilities located 210 km North of Vitoria and 40 km South of São Mateus. GeDIg-FAL pilot scope comprises the deployment of an integrated portal giving users access to several new technical solutions and collaboration capabilities. Business process revisions and change management initiatives to accelerate new work process implementation were all considered. Moreover, the FAL pilot includes the design, construction and commissioning of three collaborative environments for real time production monitoring and process analysis. This paper's objective is to describe the GeDIg-FAL Pilot Case Study, highlighting the innovations brought up and the means used to deliver intelligent energy capabilities into FAL operation, while sharing results and lessons learned from each project phase, starting with assessment all the way through operation, including a business case study development. Introduction Aiming to improve operational efficiency, Petrobras is exploring the Digital Integrated Field Management concept through a corporative program called GeDIg, which was conceived to drive a centralized pilot based evaluation of Intelligent Energy solutions for different kinds of Production Assets. According to Petrobras' vision, GeDIg consists of a new working concept based on real time data availability associated with a new integrated management model, including not only the development of new technologies, but also the implementation of new processes and structured change management efforts, allowing a better collaboration culture better incorporation by the involved people. This new integrated vision is considered a competitive advantage as the decision-making process become faster and more effective, leading to production optimization, cost reduction, reservoir recovery factor increasing and/or safer operations. Fazenda Alegre onshore field, discovered in 1996, is located in Jaguaré Council, in the EspÍrito Santo State, being an oil, water and gas producer (Figure 1). There are 59 wells currently in production and the naphthenic oil coming from them is characterized by its high viscosity, low acidity and low sulfur content, being very important and appropriate for special lubricant manufacturing such as, for example, power transformers isolation lubricant. Considering the oil API and viscosity characteristics, cycled steam injection is the method presently applied to recover Fazenda Alegre oil production from the reservoir. Because of the high temperature at the reservoir, due to steam injection, the most applied artificial lift method is rod pumping and most of their wells were drilled horizontally to increase recovery. According to the GeDIg implementation approach for Fazenda Alegre field, the Project was divided into four main phases: Diagnosis & Pre-Implementation; Implementation (Part 1/2); Implementation (Part 2/2); and Assisted Operation. The separation of the Implementation phase into two different parts was the strategy adopted to better perform the work required to complete the Project scope in addition to enable the new technologies and way of work absorption by the teams impacted.
