2017 · GS Paper 1 · Q15 · 15 marks
Petroleum refineries are not necessarily located nearer to crude oil producing areas, particularly in many of the developing countries. Explain its implications.
In short
Refineries in developing countries locate near ports and markets because crude is cheaper to move than its many products, which builds refining and exports but deepens import dependence and coastal risk. India imported about 88% of its crude in 2024-25 yet runs Jamnagar, the largest single-site refinery.
Model answer
Ghissu Editorial · Verified 4 Oct 2026 · 260 words
Refining without oilfields
Singapore and India's Jamnagar complex, the world's largest single-site refinery, run on imported crude.

Market-led distribution
The Mathura refinery gets coastal crude through the Salaya-Mathura pipeline and serves north India directly.
Value addition and flexibility
Coastal refineries anchor PCPIRs like Dahej and Paradip, make India a net product exporter, and could switch to discounted Russian crude after 2022.
Import dependence
The trade balance rides on oil prices and sea lanes such as Hormuz and the Red Sea.
Lost value for producers
Nigeria long exported crude and imported fuel until the Dangote refinery opened in 2024; Assam won Numaligarh under the Assam Accord.
Ecology and security
The December 2023 Ennore oil leak shows coastal risk, and concentrated, import-fed capacity leans on only 5.33 million tonnes of strategic reserves.
Diversify and store
Widen crude sources and expand strategic reserves.
Greener and local
Refine domestic crude near Barmer, and use green hydrogen and 20% ethanol blending to cut crude demand.
