ONGC Greenlights Mangaluru Strategic Oil Reserve Expansion

Kalpana Kanungo - Mumbai Bureau Jul 10, 2026 1,250 Views

ONGC has approved a 1.75 MMT strategic petroleum reserve in Mangaluru to enhance India’s energy security. This project, a first of its kind funded directly by ONGC, serves as a national emergency buffer against supply disruptions. The news triggered a 9% surge in MRPL shares, reflecting confidence in the infrastructure expansion.

Oil and Natural Gas Corporation (ONGC) has officially approved the development of a 1.75 million metric tonne (MMT) Strategic Petroleum Reserve (SPR) at Mangaluru, Karnataka. The project, designated as one of "national importance," marks a significant strategic pivot as the company—for the first time—uses its own funds to build out emergency crude stockpiles in alignment with directives from the Ministry of Petroleum and Natural Gas.

The board’s decision, finalized during a meeting on July 9, 2026, aims to reinforce India’s resilience against global supply chain shocks. The expansion comes in the wake of recent geopolitical instability, including the conflict in Iran, which highlighted the vulnerabilities of India's maritime energy routes, particularly the Strait of Hormuz.

Strengthening India’s Strategic Storage

Currently, India maintains strategic crude storage facilities at Visakhapatnam, Mangaluru, and Padur with a combined capacity of 5.33 MMT, operated by Indian Strategic Petroleum Reserves Ltd. (ISPRL). The proposed ONGC project—a Phase-I Extension—will increase this total capacity by approximately one-third.

The new facility will leverage the existing energy infrastructure in Mangaluru, where ONGC subsidiary Mangalore Refinery and Petrochemicals Ltd. (MRPL) operates a 300,000-barrel-per-day refinery. By integrating the new caverns with existing operations, ONGC expects to enhance both national security buffers and commercial flexibility. The board has specifically directed management to engage with the Government of India to broaden commercial utilization opportunities, allowing the reserves to serve as both an emergency buffer and a commercial asset during stable market conditions.

Market Impact and Energy Resilience

The announcement has had an immediate impact on investor sentiment, with shares of MRPL jumping 9% following the news. Market analysts suggest that the project underscores ONGC’s transition from a pure-play explorer to a broader energy infrastructure developer.

As India imports over 85% of its crude oil requirements, the expansion of strategic reserves is essential to shielding the domestic economy from price volatility and supply disruptions. Unlike previous models where state-owned refiners focused solely on commercial storage, this project marks a shift where the state-run producer is directly investing in national energy infrastructure.

Official Sources

According to regulatory filings submitted to the stock exchanges, the ONGC board has accorded in-principle approval for the Phase-I expansion at Mangaluru. The company stated that it will work closely with the Ministry of Petroleum and Natural Gas to finalize regulatory support and operational frameworks.

According to company filings, the ONGC board has directed management "to take up with the Government of India for broadening commercial utilisation opportunity with associated regulatory support" for the new facility.

Why It Matters

This development is a cornerstone of India’s updated energy security architecture. By creating a larger storage buffer, India reduces its immediate susceptibility to geopolitical tensions in the Middle East. Furthermore, the project demonstrates a sustainable financial model where strategic assets can be utilized for commercial purposes, potentially reducing the fiscal burden on the state while ensuring that the country maintains at least a month of domestic demand in reserve.
