Petrobras' goods procurement sector has undergone a significant digital transformation, shifting from manual processes to an integrated ecosystem of technological solutions. This evolution has driven operational efficiency, strengthened supplier relationships, and delivered strategic results aligned with corporate values of innovation and sustainability.
The SATRe (Automated System for Purchasing Requisition) stands out as a key innovation, integrating robotic process automation (RPA), statistical models, and machine learning to optimize critical decisions. By automating tasks such as excess inventory analysis, contract-linked purchase order generation, and material transfers, the system eliminated operational bottlenecks. Capable of processing over 50,000 requests in hours and reducing analysis time to near zero, SATRe ensured precision, compliance, and prioritized use of existing contracts. This not only accelerated procurement cycles but also strengthened trust with strategic suppliers, who now benefit from predictable demand integrated into the company’s systems.
Complementing this automation, Planeja_IA introduced AI-driven demand forecasting for materials. Leveraging machine learning algorithms, the tool selects the most suitable model for each item, achieving 80% higher accuracy for most materials analyzed. This precision enabled the creation of more efficient long-term contracts. As a result, Petrobras and suppliers gained long-term visibility, improving production planning and reducing logistics costs. Additionally, minimizing idle inventory and emergency purchases reinforced supply chain sustainability—a strategic pillar for Petrobras.
Another highlight is the SAE (Stock Utilization System). This web platform uses specialized rules to identify alternative materials in stock or available long-terms contracts, optimizing their use. A 900% increase in annual queries (from 25,000 to 250,000) reflects its effectiveness in avoiding redundant purchases. By redirecting excess inventory and existing contracts, SAE reduced operational costs and strengthened collaboration with suppliers, whose contracts are now used more strategically.
Consolidated results from this transformation are substantial: 40% reduction in average contracting time, 183,000 automated annual purchase orders via long-term contracts, and 86,000 annual inter-businesses units material transfers, optimizing corporate inventory. Saving 630,000 man-hours annually freed teams for higher-value activities, such as complex negotiations and market analysis. These metrics underscore not only efficiency gains but also a cultural shift in procurement management, where technology enables more transparent and productive supplier relationships.
In summary, tools like SATRe, Planeja_IA, and SAE demonstrate how Petrobras is reinventing its supply chain. By combining automation, intelligent forecasting, and resource optimization, the company has built a model balancing operational excellence, economic sustainability, and strategic supplier partnerships—advancements that reflect its commitment to innovation and a sustainable energy future.
