What is Oil & Gas?
Oil & Gas technology encompasses the digital systems that support the entire petroleum value chain — upstream (exploration, drilling, production), midstream (pipelines, storage, transportation), and downstream (refining, petrochemicals, fuel retail). India is the world's 3rd largest oil consumer and 4th largest LNG importer. Companies like ONGC, Reliance Industries, Indian Oil (IOCL), BPCL, and HPCL operate massive technology stacks: reservoir simulation, SCADA for pipeline management, refinery process control (DCS), fuel retail automation, and ERP systems managing ₹10+ lakh crore in annual revenue.
