Petroleum Sector

The exploration, production, distribution, and pricing of petroleum resources in India are governed by a centralized administrative setup to manage import dependency and ensure energy security.

• Ministry of Petroleum and Natural Gas (MoPNG): Formulates policies for the exploration, production, refining, distribution, marketing, and export of petroleum, natural gas, and petroleum products.
• Directorate General of Hydrocarbons (DGH): A statutory body established in 1993 under the administrative control of MoPNG to oversee the upstream sector, promote sound management of oil and natural gas resources, and advise the Ministry on exploration strategies.
• Petroleum and Natural Gas Regulatory Board (PNGRB): A statutory body set up under the PNGRB Act, 2006, to regulate downstream activities, including the refining, processing, storage, transportation, distribution, and sale of petroleum and natural gas, ensuring competitive and efficient markets.
• Oil Industry Development Board (OIDB): Provides financial and other assistance for the development of the oil industry, funded primarily through a cess levied on domestically produced crude oil.

Geological Distribution: Major Oil and Gas Basins

India’s hydrocarbon potential is spread across 26 sedimentary basins covering an area of 3.14 million square kilometers, divided into onshore and offshore regions.

Western Offshore Basin

• Mumbai High: Located off the coast of Maharashtra, it is India’s flagship offshore oilfield. Discovered in 1974, it remains the largest domestic producer of crude oil and natural gas.
• Bassein (Vasai) Field: Situated south of Mumbai High, this field is one of the largest non-associated natural gas fields in Asia.

Western Onshore Basin

• Cambay Basin: Located in Gujarat, this mature basin contains major fields such as Ankleshwar (termed the “Fountain of Prosperity” by Jawaharlal Nehru), Kalol, and Mehsana.
• Barmer Basin: Located in Rajasthan, this basin holds the Mangala, Bhagyam, and Aishwarya fields. The Mangala field is the largest onshore crude oil discovery in India in over three decades.

Eastern Offshore Basin

• Krishna-Godavari (KG) Basin: A deep-water and ultra-deep-water basin in the Bay of Bengal. The KG-D6 block, operated by Reliance Industries, noted significant deep-water natural gas discoveries.
• Cauvery Basin: Spans both onshore and offshore regions in Tamil Nadu, contributing steadily to domestic crude production.

Northeastern Basins

• Assam-Arakan Basin: The oldest hydrocarbon-producing province in India. Major fields include Digboi (where oil was first struck in 1889), Naharkatiya, and Moran-Hugrijan.

Upstream Policy Regimes and Evolution

India’s exploration and production (E&P) policy framework has transitioned over decades to incentivize global investment and maximize domestic output.

National Exploration Licensing Policy (NELP)

• Mechanism: Launched in 1997, it invited private and foreign participation via competitive bidding for exploration blocks.
• Profit-Sharing Model: Government revenue was linked to the profit made by the contractor after deducting exploration and operational costs, which often led to accounting disputes over “gold-plating” of expenses.

Hydrocarbon Exploration and Licensing Policy (HELP)

• Mechanism: Introduced in 2016 to replace NELP, bringing a fundamental shift in upstream governance.
• Revenue Sharing Model: Replaced the cost-recovery model with a transparent revenue-sharing contract where bidders share a percentage of gross revenue with the government from day one.
• Single License: Provides a unified license for the exploration and production of all forms of hydrocarbons, including conventional oil and gas, shale gas, coal bed methane (CBM), and gas hydrates.
• Open Acreage Licensing Policy (OALP): A key component of HELP allowing companies to examine expressions of interest (EoI) and select exploration blocks continuously from the National Data Repository (NDR) without waiting for a formal government tender.
• Marketing and Pricing Freedom: Grants operators the freedom to sell crude oil and natural gas in the domestic market at market-determined arm’s-length prices.

Midstream and Downstream Infrastructure

The midstream and downstream segments focus on refining raw crude oil and managing the logistics of transporting petroleum products across the country.

Refining Capacity and Hubs

• Net Exporter Status: India is a global refining hub, possessing a total refining capacity that exceeds its domestic consumption, making refined petroleum products one of India’s top export commodities by value.
• Jamnagar Refinery (Gujarat): Operated by Reliance Industries, it is the world’s largest grassroots refining complex at a single location.
• Public Sector Refineries: Major facilities include Indian Oil Corporation Limited (IOCL) at Paradip, Koyali, and Mathura; Bharat Petroleum Corporation Limited (BPCL) at Mumbai and Kochi; and Hindustan Petroleum Corporation Limited (HPCL) at Mumbai and Visakhapatnam.

Strategic Petroleum Reserves (SPR)

To insulate the economy against supply disruptions and geopolitical shocks, the Indian Strategic Petroleum Reserves Limited (ISPRL), a special purpose vehicle under MoPNG, maintains underground rock caverns to store crude oil.

Key Policy Reforms and Strategic Initiatives

National Biofuel Policy and Ethanol Blending Programme (EBP)

• Target E20: The government advanced the target to achieve a 20% ethanol blending in petrol across the country to 2025-26, shifting forward from the original 2030 timeline.
• Feedstock Diversification: Allows the use of sugarcane juice, B-heavy molasses, damaged food grains (like broken rice), and maize for ethanol production to ensure supply security without compromising food security.

Pradhan Mantri Ujjwala Yojana (PMUY)

• Objective: Launched in 2016 to safeguard the health of women and children by providing clean cooking fuel (LPG) to below-poverty-line (BPL) households, replacing polluting solid fuels.
• Economic Impact: Transformed the downstream domestic LPG market, significantly increasing the national LPG penetration rate and reducing indoor air pollution.

Deregulation of Petroleum Prices

• Petrol and Diesel: Petrol prices were completely market-linked (deregulated) in June 2010, followed by diesel in October 2014. Oil Marketing Companies (OMCs) adjust retail prices daily based on international crude benchmarks, reducing the fiscal burden of under-recoveries on the Union Budget.
• Kerosene and Domestic LPG: Subsidies are strictly rationalized and transferred directly to beneficiaries via the PAHAL (Pratyaksh Hanstantrit Labh) scheme using the Jan Dhan-Aadhaar-Mobile (JAM) trinity.

Vital Facts and Statistical Trivia for Prelims

• Import Dependency: India imports roughly 85% to 87% of its total crude oil requirements, making its fiscal deficit and inflation rates highly sensitive to international Brent crude price fluctuations.
• The Digboi Legacy: Asia’s first oil well was drilled in Digboi, Assam, in 1889, and the Digboi Refinery, commissioned in 1901, is the oldest operating oil refinery in the world.
• Taxation Anchor: Crude oil, petrol, diesel, aviation turbine fuel (ATF), and natural gas remain outside the preview of the Goods and Services Tax (GST) framework. They continue to be taxed under Central Excise Duty and State Value Added Tax (VAT), serving as a primary revenue generator for both central and state governments.
• Core Sector Weight: Petroleum Refinery Products hold the highest weight (28.04%) among the Eight Core Industries in the Index of Industrial Production (IIP).

Macroeconomic Challenges in the Petroleum Sector

• Geopolitical Vulnerability: Heavy reliance on imports from volatile regions like the Middle East and evolving supply dynamics with Russia expose India to unilateral supply cutbacks and shipping disruptions.
• Fiscal Trilemma: Balancing reasonable retail prices for consumers, ensuring profit margins for public sector OMCs, and maintaining tax revenues for developmental expenditure creates policy trade-offs during global oil spikes.
• Energy Transition Risks: Global commitments to reduce carbon emissions and the domestic promotion of Electric Vehicles (EVs) require long-term capital re-allocation away from traditional refining infrastructure into green alternatives.
