ONGC: Business Overview and Financial Analysis

Oil and Natural Gas Corporation Limited (ONGC) is India’s largest public sector crude oil and natural gas exploration and production company. The company accounts for a significant share of domestic hydrocarbon production and manages upstream exploration and production (E&P) assets across onshore fields, shallow waters, and deepwater offshore basins. Beyond its core E&P operations, ONGC has an integrated presence across refining, marketing, petrochemicals, and international exploration through subsidiaries including Hindustan Petroleum Corporation Limited (HPCL), Mangalore Refinery and Petrochemicals Limited (MRPL), ONGC Videsh Limited (OVL), and ONGC Petro additions Limited (OPaL).

ONGC Segment Revenue Mix (FY2025-26)

The company’s revenue mix is primarily driven by downstream refining and marketing operations, complemented by domestic and international exploration and production businesses.

• Refining & Marketing Segment – 88.2% of consolidated revenue
• Domestic Exploration & Production (E&P) – 14.0% of consolidated revenue
• International E&P Operations – 1.3% of consolidated revenue
• Petrochemicals Segment – 0.7% of consolidated revenue

Note: Segment percentages reflect the gross operational breakdown before inter-segment eliminations and consolidation adjustments.

Downstream refining and marketing operations remain the largest contributor to consolidated revenue, while the domestic E&P business plays an important role in the group’s overall profitability.

Full-Year Financial Performance (FY2025-26)

The full-year consolidated financial results reflect strong profit growth, supported by improved performance across key downstream subsidiaries.

• Consolidated Revenue from Operations – Rs 6,62,247 crore (-0.2% YoY)

• PAT Attributable to Owners – Rs 41,424 crore (+14.3% YoY)
• Standalone Net Profit (PAT) – Rs 32,894 crore (-7.6% YoY)
• Total Full-Year Dividend Payout – Rs 13.25 per share of face value Rs 5
• Total Dividend Outflow – Rs 16,669 crore at a 51% payout ratio

Growth in consolidated profitability was supported by improved performance across subsidiaries, which helped offset lower crude oil realisations in the standalone upstream business.

Production and Reserves (FY2025-26)

ONGC’s upstream production metrics reflect stable crude oil and natural gas output alongside continued reserve additions.

• Standalone Crude Oil Production – 18.355 million metric tonnes (MMT)
• Standalone Natural Gas Production – 19.533 billion cubic metres (BCM)
• Joint Venture Share of Crude Oil – 1.170 million metric tonnes
• Joint Venture Share of Natural Gas – 0.434 billion cubic metres
• Full-Year Reserve Replacement Ratio (RRR) – 1.17
• Cumulative 2P Hydrocarbon Reserves – 700+ million tonnes
• Total Hydrocarbon Discoveries – 3 new discoveries

Production was affected by reservoir-related challenges in certain basins and delays in equipment availability for some projects.

Natural Gas Pricing and Revenue Mix (FY2025-26)

The company’s domestic natural gas business benefited from higher realisations from new well gas production.

• Revenue from New Well Gas – Rs 6,678 crore
• New Well Gas Share of Nomination Gas Revenue – 21.0%
• New Well Gas Share of Standalone Gas Production – 17.0%
• Average APM Gas Price – USD 6.60 per mmbtu
• Average Realised New Well Gas Price – USD 8.08 per mmbtu

Higher realisations from new well gas helped support upstream gas profitability amid cost pressures.

Latest Quarterly Financial Performance (Q4 FY2025-26)

The final quarter results reflect strong consolidated profit growth, supported by improved performance across downstream businesses.

• PAT Attributable to Owners – Rs 10,820 crore (+45.6% YoY)

• Petrochemicals Segment (OPaL) EBIT – Positive Rs 456 crore
• Net Quarterly Operating Cash Flow – Rs 1,12,719 crore

Quarterly earnings growth was supported by improved margins across the refining and marketing business, which helped offset a 15.8% decline in offshore E&P segment EBIT.

Capital Allocation and Debt Position (As of March 31, 2026)

ONGC maintains a controlled leverage profile, supported by strong operating cash flows and debt reduction.

• Total Consolidated Outstanding Debt – Rs 1,42,055 crore (-7.5% YoY)

• Active Western Offshore Projects – Rs 33,075 crore worth of projects under development
