RAS question
Petroleum/crude oil in Rajasthan is primarily extracted from which area?
Correct answer: (B) Barmer-Sanchore basin.
Petroleum and crude oil in Rajasthan are primarily extracted from the Barmer-Sanchore basin.
Explanation
The Barmer-Sanchore basin is Rajasthan's primary petroleum-producing region because the Directorate of Petroleum, Government of Rajasthan records proved reserves in 38 discovered fields there and states that commercial crude-oil production began from the Mangla field on 29 August 2009. The Directorate lists producing oil and gas fields such as Mangla, Bhagyam and Aishwariya, and Cairn/Vedanta-operated fields in this basin form the core of Rajasthan's crude-oil output. Barmer-Sanchore is the key basin for petroleum extraction in Rajasthan, while the other basins are either not crude-oil producing basins or are only peripheral in comparison.
Why the other options are wrong
- (A) Kota basin is wrong because there is no oil in Kota, while Rajasthan's commercial crude-oil production is centered in Barmer-Sanchore.
- (C) Jaipur basin is wrong because petroleum extraction is not associated with Jaipur and commercial crude-oil production is centered in Barmer-Sanchore.
- (D) Bikaner basin is wrong because, although it has some reserves, Rajasthan's primary petroleum-producing region is Barmer-Sanchore.
Concept
Rajasthan's mineral and energy geography includes hydrocarbon basins and producing fields. Barmer-Sanchore links physical geography with state revenue, industry and resource-based development in RAS preparation.
