Oil and Natural Gas Corporation (ONGC), established in 1956, stands as India’s premier oil and gas exploration and production company. As a state-owned enterprise, ONGC plays a pivotal role in meeting the nation’s energy demands. The company’s business model is multifaceted, encompassing various activities within the hydrocarbon value chain, which collectively contribute to its revenue generation.
Exploration and Production (E&P) of Crude Oil and Natural Gas

At the core of ONGC’s operations is the exploration, development, and production of crude oil and natural gas. The company conducts extensive geological surveys and employs advanced technologies to discover and extract hydrocarbon reserves both onshore and offshore. The extracted crude oil is sold to domestic refineries, while natural gas is supplied to various industries, including power generation, fertilizers, and petrochemicals. This segment constitutes the primary revenue stream for ONGC.
Value-Added Products
Beyond crude oil and natural gas, ONGC produces several value-added products that contribute to its revenue:
- Liquefied Petroleum Gas (LPG): A byproduct of natural gas processing and crude oil refining, LPG is widely used as cooking fuel in households and as fuel in certain industries.
- Naphtha: Produced during the refining process, naphtha serves as a feedstock in petrochemical industries and is also used in the production of high-octane gasoline.
- C2-C3 (Ethane and Propane): These hydrocarbons are utilized in the petrochemical industry for producing plastics and other chemicals.
- Superior Kerosene Oil (SKO): Commonly used as domestic cooking and lighting fuel in rural areas.
The sale of these products diversifies ONGC’s revenue base and enhances its profitability.
Subsidiaries and Joint Ventures
ONGC has strategically expanded its operations through various subsidiaries and joint ventures:
- ONGC Videsh Limited (OVL): This wholly-owned subsidiary focuses on international exploration and production activities. OVL holds participating interests in 35 oil and gas assets across 15 countries, contributing significantly to ONGC’s overall production and revenue.
- Hindustan Petroleum Corporation Limited (HPCL): In 2018, ONGC acquired a 51.11% stake in HPCL, a major downstream refining and marketing company. This acquisition enabled ONGC to integrate its operations vertically, capturing additional value across the hydrocarbon chain.
- Mangalore Refinery and Petrochemicals Limited (MRPL): ONGC holds a significant stake in MRPL, which operates a state-of-the-art refinery with a capacity of 15 million metric tonnes per annum. This facility processes crude oil into various refined products, further contributing to ONGC’s revenue.
Financial Performance
ONGC’s financial performance reflects its robust business model:
- Fiscal Year 2023-24: The company reported a net profit of ₹40,526 crore, marking a 4.4% year-over-year growth.
- Third Quarter of Fiscal Year 2024-25: ONGC achieved a consolidated revenue from operations of ₹1,66,096.68 crore, with a net profit of ₹9,783.64 crore.
These figures underscore ONGC’s significant contribution to India’s energy sector and its strong financial standing.
Strategic Initiatives and Future Outlook
To sustain and enhance its revenue streams, ONGC is undertaking several strategic initiatives:
- Enhanced Oil Recovery (EOR) Techniques: In collaboration with global energy majors like BP, ONGC is implementing advanced EOR methods to boost production from mature fields. For instance, BP has committed to increasing oil production by 44% and gas output by 89% from India’s largest oil field under a decade-long contract.
- Diversification into Renewable Energy: Recognizing the global shift towards sustainable energy, ONGC is exploring opportunities in renewable energy sources such as biofuels, ethanol, compressed biogas, and solar power. This diversification aims to complement its traditional hydrocarbon business and align with environmental objectives.
- Digital Transformation: ONGC is investing in digital technologies to enhance operational efficiency, optimize resource utilization, and improve decision-making processes.
Challenges
Despite its strengths, ONGC faces several challenges:
- Volatility in Global Oil Prices: Fluctuations in international crude oil prices can significantly impact revenue and profitability.
- Regulatory Environment: Changes in government policies, taxation, and environmental regulations can affect operations and financial performance.
- Sustainability Concerns: As the world moves towards cleaner energy sources, ONGC must balance its core hydrocarbon activities with sustainable practices and investments in renewable energy.
Conclusion
ONGC’s comprehensive business model, encompassing exploration and production, value-added products, strategic subsidiaries, and forward-looking initiatives, has established it as a cornerstone of India’s energy infrastructure. By leveraging its core competencies and adapting to evolving market dynamics, ONGC continues to play a crucial role in ensuring the nation’s energy security while pursuing sustainable growth avenues.
