Client overview

A state-owned petroleum and natural gas organization serves as the national oil company of Saudi Arabia. As of 2022, it is the second-largest company in the world by revenue and is headquartered in Dhahran. The organization also captures emissions and converts them into useful industrial products and manufacturing feedstocks that support economic growth and job creation. These efforts, along with other sustainability strategies, have helped it achieve one of the lowest CO₂ footprints in the oil and gas industry.

Solution offered

The blockchain-based contractor services platform was developed to transform a client’s USD 20 billion annual contractor service operations by increasing efficiency, transparency, and cost-effectiveness. The solution integrated six key partner systems—SAP ERP, contractor networks, banking systems, government platforms, internal applications, and third-party services—creating a secure, digital ecosystem for seamless collaboration. The user-friendly front end, built with JavaScript and HTML/CSS, supported internal teams and contractors, while the back end leveraged Hyperledger Fabric, SAP HANA, Node.js, and Java for scalable, high-performance processing.

Integration tools such as IBM MQ, REST APIs, and SAP Process Orchestration ensured smooth data exchange across platforms. Additional technologies, including Kubernetes, NFC, Bluetooth, RFID, and Innovatrics APIs, expanded system functionality. The platform addressed major challenges such as inefficient invoice processing, security concerns, high transaction costs, and compliance requirements. Automated, blockchain-based verification accelerated invoice handling, improved cash flow visibility, and enhanced data security through encryption and zero-knowledge proofs. Overall, the solution delivered a secure, future-ready environment that strengthened operational efficiency and transparency.
