Andhra Pradesh, Arunachal Pradesh, Assam, Gujarat, Rajasthan, and Tamil Nadu are the petroleum-producing states in India. Petroleum is a yellowish-black liquid mixture of mainly hydrocarbons. It is also known as crude oil. The formation of petroleum takes place when large quantities of dead organisms, mostly zooplankton, and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure.

The oil deposits in the country were discovered first in 1889 near the town of Digboi in the state of Assam. Petroleum includes crude oil, all liquid, gaseous and solid hydrocarbons. Gases exist in the form of lighter hydrocarbons methane, ethane, propane, and butane and heavier hydrocarbons are in the form of liquids or solids under surface pressure and temperature conditions.
