Why is India expanding its Strategic Petroleum Reserves at this time?

India imports more than 85% of its crude oil, leaving its economy highly vulnerable to global price shocks and supply disruptions. By expanding the Mangalore facility, the government aims to increase its strategic buffer, ensuring economic stability during geopolitical crises in key supply regions like the Middle East.

How does the Mangalore expansion fit into India's broader energy strategy?

The 1.75 million ton expansion is a key component of India's Phase II SPR expansion plan, which transitions the country toward a commercial-cum-strategic storage model. This model allows the government to lease storage space to international oil companies, offsetting construction costs while retaining the right of first refusal on the crude during emergencies.

What are the technical characteristics of the Mangalore storage facility?

The Mangalore facility utilizes unlined underground rock cavern technology, which is considered the safest and most cost-effective method for storing large volumes of crude oil. These caverns rely on natural hydrostatic pressure from surrounding groundwater to prevent oil from leaking, offering superior protection against external hazards compared to above-ground tanks.

India to Expand Crude Reserves

Analysis

AI-assisted analysis · reviewed by Yuri Kan

India's state-run energy giant, ONGC, has approved a major expansion of the nation's Strategic Petroleum Reserves (SPR) by adding 1.75 million metric tons of capacity at the Mangalore facility in Karnataka. This decision marks a critical step in New Delhi's ongoing efforts to bolster its energy security shield against volatile global crude markets and supply chain disruptions. By expanding its underground rock cavern storage, India aims to increase its import cover days, aligning with its strategic goal of mitigating geopolitical risks in the Middle East and beyond.

Key Facts

The board of India's largest state-owned oil and gas producer, Oil and Natural Gas Corporation (ONGC), approved the expansion project.
The project will add 1.75 million metric tons of crude oil storage capacity to the national reserves.
The expansion will be located at the existing strategic petroleum reserve site in Mangalore, in the southwestern state of Karnataka.
This initiative is part of India's Phase II of its Strategic Petroleum Reserve program, which focuses on commercial-cum-strategic storage models.
India currently imports over 85% of its crude oil requirements, making the expansion of domestic storage a matter of national security.
The Mangalore facility currently holds 1.5 million metric tons of capacity, meaning this expansion will more than double the site's storage footprint.

Background & Context

India established its Strategic Petroleum Reserve (SPR) program under the management of Indian Strategic Petroleum Reserves Limited (ISPRL) to safeguard the economy from supply disruptions. Phase I of the program built 5.33 million metric tons of capacity across three locations: Visakhapatnam, Mangalore, and Padur, providing roughly 9.5 days of net import cover. As global energy markets grew increasingly volatile due to OPEC+ production cuts and geopolitical conflicts, the Indian government approved Phase II to add another 6.5 million metric tons of capacity through public-private partnerships.

Market Impact

This expansion significantly enhances India's leverage in the global crude market, allowing the world's third-largest oil consumer to buy opportunistically during price dips. For global oil exporters, particularly in the Middle East and Russia, India's growing storage capacity means a more stable, long-term buyer, though it also grants New Delhi greater bargaining power during price negotiations. Domestically, the project will stimulate engineering and construction sectors in Karnataka, while providing Indian refiners with a sturdier buffer against sudden maritime chokepoint closures or geopolitical escalations.

What to Watch

Moving forward, the market will watch for the tendering process and the selection of engineering partners to construct the new Mangalore caverns. Analysts will also monitor whether India can successfully attract foreign state oil companies, such as ADNOC or Saudi Aramco, to lease portions of this new capacity under commercial terms. The timeline for completion is expected to span the next three to four years, closely watched by global energy security observers.
