Oil India Limited (OIL.NS) Bundle
From the first gush of crude in Digboi in 1889 to being awarded Maharatna status in 2023, Oil India Limited (OIL) has grown from a regional pioneer into India's second-largest oil and gas company-contributing roughly 13% of the nation's crude production and 9% of its natural gas-backed by domestic reserves of 69.39 million tonnes of oil and 139.03 billion cubic meters of gas (as of March 31, 2025); established as a public sector enterprise in 1959, OIL today operates across upstream exploration (62 blocks covering 92,888 km²), midstream transport (including the landmark 1,157 km Naharkatiya-Barauni crude pipeline), and downstream refining via a 69.63% stake in Numaligarh Refinery Ltd (now at 9 million tonnes per annum capacity), while the Government of India retains a 56.66% majority stake and the company reported a market capitalization of ₹1,24,907.21 crore on August 30, 2024; with paid-up capital of ₹1,626.61 crore and ambitions to lift domestic output to 7.5 million tonnes of oil equivalent by FY2026 alongside a net‑zero by 2040 pledge, OIL is diversifying into renewables and international ventures to expand revenues from exploration, pipeline tariffs, refining margins, and new energy streams.

Oil India Limited (OIL.NS): How It Works
Oil India Limited (OIL.NS) is a state-owned upstream oil and gas company that combines exploration & production (E&P), midstream transportation, refining via a subsidiary, and emerging renewables to generate cash flow and shareholder value. Its revenue mix and cash generation are driven by volumes produced, realized international and domestic hydrocarbon prices, pipeline tariffs, refining margins at Numaligarh Refinery Limited (NRL), and returns from overseas equity ventures.- Exploration & Production (E&P): OIL conducts onshore and offshore exploration using seismic, drilling, and reservoir management; hydrocarbon sales (crude oil and natural gas) make up the largest share of revenue.
- Midstream transportation: OIL owns and operates trunk pipelines and charging tariffs for movement of crude oil and condensates, collecting steady fee income.
- Refining (via NRL): The company realizes additional margin by supplying crude to Numaligarh Refinery Limited (its subsidiary/joint-venture partner) and from product sales (MS, HSD, LPG, petrochemicals).
- International upstream stakes: Equity oil and gas from overseas projects (Russia, Venezuela partner arrangements, Africa, Bangladesh) add production-linked revenue and diversify source of supply.
- Renewables & non-core income: Wind and solar projects, land leases, services, and contract drilling provide ancillary income and strategic diversification.
| Item | Representative Metric / FY ≈ |
|---|---|
| Crude oil production (annual) | Approximately 2.5-3.0 million tonnes |
| Natural gas production (annual) | Approximately 3.0-3.5 billion cubic meters (bcm) |
| Revenue (consolidated) | Approximately ₹18,000-22,000 crore |
| Net profit / PAT (consolidated) | Approximately ₹4,000-7,000 crore |
| Market capitalization (approx.) | ₹30,000-50,000 crore |
| Pipeline network length | Several hundred kilometers of trunk pipelines (crude and condensate) |
| Numaligarh Refinery (throughput) | Refinery capacity ~3-3.0 MMTPA (approx. nameplate capacity at Numaligarh ~3.0 million tonnes per year) |
- Hydrocarbon sales - direct sale of produced crude and gas to domestic refiners, traders, or under production-sharing arrangements; prices linked to international crude benchmarks and domestic gas price regimes.
- Pipeline tariff income - regulated/contractual tariffs provide predictable fees for transporting crude from fields to refinery or storage points, smoothing volatility from commodity prices.
- Refining margins - supply to NRL or third-party product sales capture downstream value-add; refinery utilization and product cracks determine incremental profitability.
- International equity oil/gas - proportionate share of production from overseas ventures is booked as revenue or as equity income depending on accounting; can introduce currency and geopolitical risk but also upside when host-country prices are favorable.
- Renewables & services - lower-margin, steady income from power generation (solar/wind), field services, and logistics that complement cyclical oil & gas cashflows.
- Production optimization - drilling efficiency, improved recovery techniques, and infill wells raise barrels/day and reduce unit cost.
- Cost control - operating expenditure discipline (OPEX per barrel), supply-chain optimization, and joint-venture cost sharing improve margins.
- Realized price management - hedging where applicable, long-term offtake contracts, and portfolio sales strategy reduce exposure to spot price swings.
- Asset allocation - capital expenditure (CAPEX) prioritization (E&P vs. pipelines vs. renewables) and strategic divestments influence future revenue mix.
- Strategic investments - stakes in overseas projects and participation in midstream/downstream ventures diversify revenue and offer access to incremental barrels.
- Upstream sales: Field operator sells crude to a domestic refiner - revenue recorded at prevailing realized price minus transportation/handling; volumes billed monthly.
- Pipeline income: Shipper books capacity; OIL invoices fixed/variable tariffs - contracted revenue stream independent of commodity price movements.
- Refinery product sales: NRL processes crude into products, sells to domestic marketing companies - margins recognized after refining costs and adjustments.
- International equity: OIL's share of production from a foreign JV is either taken in-kind (sold) or sold by JV operator and proceeds distributed - contributes to consolidated revenue or associates' income.
- Renewable power: Solar/wind output sold under power purchase agreements (PPAs) - predictable tariffs and duration add stable non-hydrocarbon cash flow.
- Revenue sensitivity to crude price: A 10% shift in Brent/Indian crude realizations typically moves consolidated top line materially because hydrocarbons dominate sales.
- Volume sensitivity: A 5-10% change in annual production has direct proportional impact on oil & gas sales; pipeline tariff income is less sensitive.
- Refining margin sensitivity: Product cracks influence downstream EBITDA depending on refinery utilization and crude slates processed at NRL.
- FX & geopolitical risk: Overseas revenue and costs (e.g., Russian or African projects) expose OIL to currency translation and geopolitical variables.
| Metric | Why it matters |
|---|---|
| Production (bbl/day or tonnes per year) | Drives scale of sales and unit economics |
| Realized crude & gas prices | Determines top-line and gross margins |
| Operating cost per barrel | Reflects efficiency and margin resilience |
| EBITDA and EBITDA margin | Measures operating profitability across cycles |
| Free cash flow | Available for dividends, debt servicing, CAPEX and acquisitions |
