What is Strategic petroleum reserves?
Historical Background
Key Points
12 points- 1.
Strategic Petroleum Reserves are essentially massive underground storage facilities, typically built in rock caverns or salt caverns, designed to hold crude oil. This underground storage is safer, more cost-effective, and environmentally less impactful than above-ground tanks, protecting the oil from natural disasters, sabotage, or rapid evaporation.
- 2.
The primary purpose of these reserves is to provide a buffer against sudden oil supply disruptions caused by geopolitical events like wars, blockades, or natural calamities suchations. For example, if the Suez Canal were blocked for an extended period, these reserves would ensure India's refineries continue to operate.
- 3.
When a crisis hits, the government can decide to release oil from these reserves into the market. This immediate injection of crude oil helps to stabilize domestic fuel prices, prevent panic buying, and ensure that essential services and industries continue to receive fuel, thereby cushioning the economic impact of the disruption.

Frequently Asked Questions
121. What is the most common MCQ trap regarding India's SPR capacity and the IEA's 90-day rule?
The common trap is confusing India's actual dedicated Strategic Petroleum Reserves (SPR) capacity with its total oil stock buffer. While the International Energy Agency (IEA) recommends a 90-day reserve of net imports, India's dedicated SPRs (Phase I) hold about 39 million barrels. However, when combined with refinery stocks, India's total buffer is roughly 66 to 70 days. Examiners often ask about India's compliance with the 90-day rule, implying only SPRs, whereas the broader context includes refinery stocks.
Exam Tip
Remember that "SPR capacity" (39 million barrels) is distinct from "total oil buffer" (SPR + refinery stocks, 66-70 days). UPSC often tests this nuance.
2. How do Strategic Petroleum Reserves differ fundamentally from the crude oil stocks maintained by refineries, and why is this distinction crucial for exam purposes?
The fundamental difference lies in their purpose and accessibility. Refinery stocks (around 25 days) are operational inventories meant for daily processing and maintaining continuous supply to the market. SPRs, on the other hand, are 'dead storage' – a national emergency reserve meant only for extreme supply disruptions, like wars or blockades, to ensure energy security and prevent economic collapse. This distinction is crucial because SPRs are not for commercial use or routine market stabilization.
