Government of India is fast filling up India’s Strategic Underground Oil Reserves; Are we preparing for War? #Hindustan360

India’s strategic plan to build an emergency stockpile with millions of barrels of crude oil, on the lines of the reserves that the US and its Western allies set up after the first oil crisis of 1973-74, is in the rollout phase. View more at #Hindustan360.

Under the first stage of the Strategic Petroleum Reserve project, underground rock caverns for total storage of 5.33 MMT of crude oil at three locations — Visakhapatnam (1.33 MMT), Mangalore (1.5 MMT) and Padur (2.5 MMT) have been commissioned. The facility at Visakhapatnam, deep in the bowels of the earth, in underground rock caverns connected by tunnels extending over 7 km under the hills around Andhra Pradesh’s biggest city, has already been filled up while nearly a quarter of the Mangalore storage facility has also been filled. The storage facility at Padur has also been completed and commissioning is expected shortly. The total approved expenditure for the entire project is Rs 4,098.35 crore, of which 3,552.59 has already been disbursed till the end of October, officials indicated.

Each of these projects involved substantive civil works. In the Visakhapatnam project, to create the caverns, nearly 8 million cubic metres of rock that weighed over 21 million tonnes had to be scooped out of the earth. In the run-up to the commissioning, water was let into the rocks around the tunnel at high pressure to prevent the crude from seeping out — a process called ‘hydraulic confinement’ — and the mouths of the tunnels were then sealed with concrete plugs three metres thick by the executing utility — the Indian Strategic Petroleum Reserves Limited (ISPRL) — a special purpose vehicle floated as a wholly-owned subsidiary of the Oil Industry Development Board for the management of the strategic crude storage. The other two projects at Mangalore and Padur, both on the west coast of Karnataka, were offered pipeline connections from the nearest ports early this year.

Crude oil from the reserves are to be released by an empowered committee constituted by the government, in the event of any supply disruptions from abroad. These include any natural calamity or any unforeseen global event, leading to an abnormal increase in prices. Apart from the capital cost of Rs 4,098 crore, the crude oil cost would be approximately Rs 11,725 crore.

While the concept of massive caverns deep below the surface of the earth has been traditionally marketed as an energy security measure that can be a defence against an attack or invasion of some sort, underground storage is, by far, also the most economic method of storing petroleum products.

According to an expert from the National Institute of Rock Mechanics, Kolar, Karnataka, the underground facility rules out the requirement of large swathes of land, loads of security, ensures less evaporation and, since the caverns are built much below the sea level, it is easy to discharge crude into them from ships.

The three storage facilities to be implemented in the first phase can hold 13 days of India’s crude stock requirement. The International Energy Agency (IEA) actually recommends 90 days. So, clearly, there is need to build more. A second phase is also under planning, which seeks to create 12.5 million tones of storage capacity, at Padur, Chandikhol (Odisha), Bikaner (Rajasthan) and Rajkot (Gujarat). Chandikhol is likely to be underground concrete tanks while in Bikaner, which has mountains of salt underground, a cavern is easy to build.

Highlights

  • Underground storage facilities at Visakhapatnam has already been filled up
  • Nearly a quarter of the Mangalore storage facility has also been filled
  • Underground Storage facility at Padur has also been completed and commissioning is expected shortly

Global Crude Reserves

United States:

The country’s Department of Energy’s Strategic Petroleum Reserve (SPR) is an emergency fuel storage that is the largest emergency supply in the world with the capacity to hold up to 727 million barrels. As of end-February 2015, the inventory was 691.0 million barrels, which was equivalent to about 37 days of oil at 2013 daily US consumption levels of 18.49 million barrels per day. The total value of the crude in the SPR is approximately $43.5 billion. The United States started the petroleum reserve in 1975 after oil supplies were cut off during the 1973-74 oil embargo, to tide over future temporary supply disruptions. The SPR management office is located in New Orleans, Louisiana. The reserve is stored at four sites on the Gulf of Mexico, each located near a major centre of petrochemical refining and processing. Each site contains a number of artificial caverns created in salt domes below the surface.

Japan:

The country has the second largest emergency supply of oil with a reported capacity of close to 600 million barrels. The SPR is composed of two types of stockpiles — state controlled reserves at eleven different locations totaling 324 million barrels and privately-held reserves of petroleum held “in accordance with the Petroleum Stockpiling Law” of 129 million barrels. The Japanese SPR is run by the Japan Oil, Gas and Metals National Corporation.

China:

The Chinese Strategic Petroleum Reserve consists of a government-controlled strategic reserve complemented by mandated commercial reserves. The planned state reserves of 475 million barrels plus the planned enterprise reserves of 209 million barrels are expected to provide around 90 days of consumption or a total of 684 million barrels.

European Union:

In the European Union, according to Council Directive of December 20, 1968, all 27 members must have a strategic petroleum reserve within the territory of the EU equal to at least 90 days average daily internal consumption.
