Considering known oil producing regions in India, which of the following sets of fields CORRECTLY belongs predominantly to Assam (north east)?

The correct answer is Digboi, Naharkatiya, Moran . Key Points Digboi : Known as the birthplace of the oil industry in India, Digboi is located in the Tinsukia district of Assam. It holds historical significance as the first location in Asia where oil was drilled in 1889. It is home to one of the world's oldest operational oil refineries. Naharkatiya : Located in the Dibrugarh district of Assam, this oil field is one of the largest and most productive in the state. Oil from Naharkatiya has played a crucial role in meeting India's energy demands since its discovery in the 1950s. Moran : Another significant oil field in Assam, Moran is located in the Dibrugarh district. This field has contributed to the state's status as a major oil-producing region in India. These fields are part of the Assam-Arakan basin, which is one of the most important sedimentary basins in India for hydrocarbon exploration and production. The dominance of Assam in oil production is due to its abundant reserves and the historical development of oil exploration activities in the region. Additional Information Oil Production in Assam: Assam accounts for a significant portion of India's crude oil production, contributing approximately 13% of the country's total crude oil output . The Assam-Arakan basin is classified as a Category-I basin by the Directorate General of Hydrocarbons (DGH), denoting its high potential for hydrocarbon resources. Major companies like Oil India Limited (OIL) and ONGC are actively involved in exploration and production activities in Assam. The Brahmaputra valley serves as the focal area for oil and gas exploration in the state. Significance of the Assam Oil Fields: They contribute significantly to India's energy security by reducing dependence on imported oil. The oil fields have also spurred economic development in the region, providing employment and boosting infrastructure development. Assam's oil industry has historical importance, as it marked the beginning of India's journey in hydrocarbon exploration and production. Other Major Oil Fields in India: Ravva Field : Located in Andhra Pradesh, it is a significant offshore oil and gas field. Bombay High : An offshore oil field in the Arabian Sea, it is one of the largest contributors to India's crude oil production. Ankleshwar : Located in Gujarat, this field is another important contributor to the nation's oil production. Challenges in Oil Production: Environmental concerns, including the impact of drilling and production activities on the local ecosystem. Technological challenges in extracting oil from deeper and more complex reservoirs. Economic factors, such as fluctuations in global oil prices and the cost of production. Important Points Digboi Refinery : Established in 1901, it is Asia's first oil refinery and continues to operate, symbolizing India's rich history in oil exploration. Oil Reserves in Assam: The state has an estimated reserve of approximately 1.3 billion barrels of crude oil. Environment-Friendly Practices: Companies like OIL and ONGC are increasingly adopting sustainable practices to minimize the environmental impact of oil production. Future Prospects: With advancements in technology and increased investment, the exploration of untapped reserves in Assam is expected to grow, further boosting the state's oil production capacity.
