Oil Well Locations in India

India is a significant consumer of petroleum products, and it also has its own domestic production of crude oil and natural gas. These valuable resources are extracted from various regions across the country.

Oil wells, which are used to tap into underground oil reserves, are concentrated in specific geological formations. Historically and currently, one of the most important regions for oil extraction in India is located in the northeastern part of the country.

Among the options provided, Assam is widely recognized as a pioneering state in India's oil industry. It has been producing crude oil for over a century. Significant oil fields in Assam include Digboi, Naharkatiya, and Moran-Hugrijan, among others.

While other states like Gujarat, Rajasthan, and offshore areas (like Mumbai High) are also major contributors to India's oil and gas production, Assam stands out as having some of the oldest and most prominent onshore oil fields in the country. The options Goa, Karnataka, and Orissa (now Odisha) are not primary regions known for significant crude oil well operations.

Therefore, when considering the locations of oil wells in India from the given options, Assam is the correct identification of a state where oil wells are found.
