Which Indian state is the top producer of crude oil and petroleum reserves as of recent geological surveys?

💡 Solution & Explanation

Rajasthan has emerged as the leading onshore crude oil-producing state in India, driven by prolific oilfields in the Barmer basin operated by private and public sector joint ventures. Alternative options like Gujarat and Assam have historical significance as older petroleum regions but currently yield lower total volumes than Rajasthan. Mumbai High remains the preeminent offshore crude oil production facility regulated by the central government.
