Foreseeing near future opportunities for oil and gas fields, Petrobras created a corporate program dedicated to study, develop, and implement Digital Integrated Field Management (GeDIg) among its production assets.
Over the last three years, Petrobras has been developing a pilot strategy based on multiple scenarios to evaluate the technology level of digital oilfields. Six assets were chosen, taking into account the diversity of production processes (heavy oil, offshore, onshore, brown, and green fields) found all over the Brazilian fields. Two different approaches were implemented: in-house development and partnership with integrated companies.
Petrobras program is supported by three fundamental elements: people, process, and technology. Humanware, workflow processes, and change management are the key factors for new technologies implementation such as collaboration centers, intelligent completion, and fast loop artificial lift optimization.
After the pilots first year of operation, lessons learned will be gathered to guide the expansion of the digital oilfield concept for other Petrobras assets. The objective of this work is to describe the methodology applied in the six pilots and how Petrobras is going to improve its digital way of work and add value to its assets with Digital Integrated Oil and Gas Field Management.
Introduction
E&P is moving towards a new digital era, where technology supports new workflow processes, and Petrobras, foreseeing the near future opportunities for oil and gas fields, created a corporate program dedicated to study, develop, and implement Digital Integrated Field Management (GeDIg) among its production assets. Petrobras defined a pilot strategy based on multiple production scenarios, taking into account its production processes diversity (heavy / light oil, brown / green, offshore / onshore fields). The main goal of the pilot strategy is to evaluate the benefits of digital oilfield implementation, combining production scenarios with asset intelligence level. Six assets were chosen and different approaches were considered. In each pilot, the digital fields are being designed with real time operation, data base integration, and collaborative functional model to achieve faster decisions based on concise and reliable information. To implement the new digital way of work, humanware, workflow processes redesign, and change management become important tools to transform the processes into its TO BE form.
The methodology applied in the pilot strategy is presented in the next section, followed by the detailed description of each pilot. At the end, the lessons learned from the GeDIg program will be presented.
Pilot Strategy
Digital Integrated Field Management (GeDIg) is E&P integrated management for production processes to add value to oilfield through personnel training and right time information access (automation, modeling and simulation). In addition, GeDIg aims real time monitoring and control, production and cost optimization, pursuing ultimate reservoir recovery augmentation. Besides digital oilfield benefits evaluation, GeDIg program expects to design the best strategy for a multi-production scenario in broad digital field implementation.
