Digital Shift: Technology trends redefining the oil and gas sector

The oil and gas (O&G) sector is undergoing a technological transformation, driven by the imperative to enhance operational efficiency across the value chain and the regulatory focus on clean energy. Indian energy companies are increasingly investing in advanced technologies to maximise asset performance, reduce lifecycle costs and strengthen operational resilience amid shifting energy demand and environmental standards. Digitalisation offers substantial benefits, such as a 50-70 per cent reduction in exploratory data interpretation times and 20-40 per cent lower maintenance costs. In the downstream segment, city gas distribution (CGD) has witnessed exponential growth, with the development of more than 8,100 CNG stations and the achievement of over 15 million domestic PNG connections as of May 2025. This exponential growth, along with rising natural gas demand and policy support, has intensified the need for real-time asset monitoring, predictive maintenance and customer-centric digital platforms. As a result, the sector’s digital priorities are becoming increasingly centred on converging IT and operational technology (OT); scaling up next-generation technologies such as digital twins, artificial intelligence (AI) and machine learning (ML); and deploying integrated analytics, etc., across upstream, midstream and downstream operations. Further, internet of things (IoT)-enabled sensors and smart devices are being deployed across the value chain, from upstream field operations to downstream logistics, to enable real-time asset monitoring, leak detection and personnel safety.

Technologies enhancing upstream operations

The growing uptake of advanced technologies in upstream O&G operations in India is aimed at improving efficiency, reducing costs and enhancing operational competence in a capital-intensive and data-driven segment. As the sector evolves from Industry 4.0 to the emerging paradigm of Industry 5.0, characterised by deeper human-machine collaboration, the convergence of IT and OT systems becomes increasingly important. This integration is critical for real-time asset monitoring, predictive maintenance and data-informed decision-making. Upstream activities such as exploration and production, with their long gestation periods and high investment thresholds, particularly benefit from technologies like digital twins, edge computing, advanced analytics and AI/ML-driven models.

In line with this, key O&G players are actively responding to this shift. Among these, Oil and Natural Gas Corporation Limited (ONGC) has rolled out initiatives such as SAP system upgrades, chatbot development, business intelligence dashboards and software-defined wide area network deployment for enhanced cybersecurity. Its digital transformation is anchored around two key performance indicators (KPIs) – reducing the cost of producing a barrel of oil and minimising manpower requirements. Importantly, ONGC’s approach also reflects a growing preference for developing in-house IT-OT capabilities over reliance on external vendors to retain greater control and enhance cybersecurity. In addition, a few broader trends are emerging across the segment, such as the phased adoption of open standards (like OPC UA and MQTT) and cross-functional digital governance teams that enable integrated and intelligent systems. Emerging strategies like zero-trust architecture, autonomous operations and sustainability-driven digitalisation are also beginning to shape upstream digital roadmaps.

Midstream operations benefitting from digital solutions

Digital transformation in midstream O&G operations is gaining momentum as companies seek to enhance process reliability and improve operational agility. Some important initiatives include GAIL India Limited’s Rs 8.44 billion investment, approved in June 2025, for expanding the Dahej-Uran-Dabhol-Panvel gas pipeline network beyond just capacity augmentation. Apart from increasing throughput from around 19.9 million metric standard

cubic metres per day (mmscmd) to 22.5 mmscmd, the project integrates advanced supervisory control and data acquisition (SCADA) systems, IoT-enabled real-time flow monitoring, predictive maintenance sensors and pipeline-integrity analytics. Similarly, in April 2025, Indian Oil Corporation Limited (IOCL) collaborated with ABB India to deliver integrated automation and digital solutions across its pipeline system, improving real‑time monitoring, safety and cybersecurity posture. ABB India had earlier delivered a transformative digital upgrade to IOCL’s expansive O&G pipeline network via its centralised pipeline information management system. This system enables seamless data acquisition, advanced diagnostics, predictive maintenance and decision support capabilities, all critical for optimising pipeline operations and maintaining safety standards.

Digitalisation of downstream O&G operations

The downstream segment is witnessing the implementation of several digital initiatives for enhancing asset management, operational efficiency and customer service. Technologies such as geographic information systems (GIS), SCADA, enterprise resource planning (ERP) and predictive analytics are being deployed across refining and distribution networks. GIS is particularly transformative in managing underground pipeline infrastructure, enabling spatial visualisation of networks, optimising asset placement and supporting emergency response. SCADA systems enhance real-time visibility and control, while ERP platforms facilitate data integration and business intelligence for effective decision-making.

Among the various associated initiatives, Avantika Gas Limited has implemented a comprehensive GIS framework that integrates asset data, customer demographics and urban development trends to support planning, risk mitigation and operational decision-making. This system not only helps field engineers locate assets swiftly during emergencies but also informs bidding strategies and infrastructure expansion through deep spatial analysis. Additionally, SCADA has been deployed to monitor flow, pressure and temperature in real time, streamlining processes such as pricing updates and resource allocation. The integration of SCADA and GIS has significantly improved responsiveness to system abnormalities, while reducing gas losses and enhancing safety. Meanwhile, Numaligarh Refinery Limited (NRL) is leveraging condition monitoring tools such as GE’s System 1, Meridium APM and a sensor-enabled integrated condition monitoring system to drive predictive maintenance and improve equipment reliability. Its smart fleet management system, integrated with SAP and GPS, automates billing and enforces fuel quotas, while digital dashboards aggregate key performance indicators across departments to support ERP.

Drones and dynamic inventory tracking are also helping operators reduce downtime and improve response times, while digital twin technology is proving transformative in refining processes. For instance, NRL has implemented a facility digital twin for its Numaligarh Refinery Expansion Project, enabling lifecycle asset management and centralised access to engineering data. Along similar lines, Bharat Petroleum Corporation Limited (BPCL) has adopted digital twins, robotics and augmented reality/virtual reality at its Mumbai, Kochi and Bina refineries. It has also implemented distributed control systems and advanced process control systems, which serve as the backbone of intelligent refinery operations. These platforms enable automated monitoring, precise process adjustments and the integration of data across units, helping BPCL to reduce energy consumption, emissions and unplanned downtimes. Moreover, its digital roadmap includes cybersecurity integration through OT security operations centres and partnerships with vendors like Honeywell and Yokogawa.

Challenges and the way forward

The adoption of digital technologies in the sector, particularly in the CGD segment, is gaining traction but continues to face multiple systemic and operational challenges. The major one among these is cybersecurity, as the increasing digitalisation of customer and operational data exposes companies to the growing threats of cybercrime and data breaches. Many CGD operators also lack a cohesive digital roadmap, resulting in the fragmented deployment of systems like ERP, CRM and smart metering platforms. Skill shortages, especially in areas such as instrumentation, data integration and cybersecurity, further hamper progress, while resistance to change among personnel limits the effectiveness of well-designed solutions. Legacy infrastructure, commonly found at upstream sites and in older distribution networks, poses interoperability issues, making the integration of modern IT-OT systems complex and costly. Despite the promise of long-term savings, budget constraints often slow the adoption of advanced technologies like digital twins, AI-based analytics and real-time monitoring systems.

Going forward, the sector is evolving through digitalisation, especially in downstream and CGD operations. As the share of natural gas in India’s energy mix rises, with CNG stations projected to grow to over 17,500 and domestic PNG connections expected to reach over 120 million by 2030, the need for smart, scalable and secure digital infrastructure becomes critical. The key focus areas for resilient adoption include focused IT-OT integration, cybersecurity by design and workforce upskilling. Emerging strategies like autonomous operations, modular IT architectures and digital sustainability platforms, along with advanced telemetry solutions leveraging 5G and satellite connectivity, promise to make even remote and complex operations more manageable.
