ONGC discovers oil, gas reserves in Madhya Pradesh, West Bengal

State-owned Oil and Natural Gas Corp (ONGC) has made oil and gas discoveries in Madhya Pradesh and West Bengal that may potentially open up two new sedimentary basins in country. They are category-III basins, having hydrocarbon and are considered geologically prospective for exploration.

Key Facts

Madhya Pradesh: The gas deposits were discovered in block in Vindhyan basin. This find is at 3,000-plus meters deep and is being now tested. Four wells drilled after discovery and now hydro-frack will be undertaken to test commerciality of this field.

West Bengal: Oil and gas was discovered in well in Ashok Nagar of 24 Parganas district. Around one lakh cubic meters per day of gas has flowed from one object that was tested.


India has 26 sedimentary basins, of which only seven category-I basins have commercial production of oil and gas. Except for Assam shelf, ONGC opened up all the other six basins, including Cambay, Mumbai Offshore, Rajasthan, Krishna Godavari, Cauvery, and Assam-Arakan Fold Belt for commercial production. The seventh basin was opened way back in 1985. It is in the process of adding eighth basin by putting Kutch offshore discovery (it holds about one trillion cubic feet of gas reserves) to production.

26 sedimentary basins (category wise)

Category-I basins: Cambay, Mumbai Offshore, Rajasthan, Krishna Godavari, Cauvery, Assam Shelf and Assam-Arakan Fold Belt. They have been established for commercial production.

Category-II basins: Kutch, Mahanadi-NEC (North East Coast), Andaman-Nicobar, Kerala-Konkan-Lakshadweep. They are known for accumulation of hydrocarbons but no commercial production has been achieved so far.

Category-III basins: Himalayan Foreland Basin, Ganga Basin, Vindhyan basin, Saurashtra Basin, Kerela Konkan Basin, Bengal Basin. They having hydrocarbon and are considered geologically prospective.

Category-IV basins: Karewa, Spiti-Zanskar, Satpura–South Rewa–Damodar, Chhattisgarh, Narmada, Deccan Syneclise, Bhima-Kaladgi, Bastar, Pranhita Godavari and Cuddapah. They have uncertain potential which may be prospective by analogy with similar basins in the world.

ADB to $245 million provide loan for safe, sustainable drinking water service in West Bengal

Asian Development Bank (ADB) has approved financing package of $245 million to implement project for providing safe, sustainable drinking water service to million people in three districts of West Bengal affected by arsenic, fluoride, and salinity. The project will provide continuous potable water through metered connections to about 390,000 individual households in three districts of North 24 Parganas, Bankura and Purba Medinipur. This project will play pivotal role in reducing burden of disease from arsenic and fluoride while preserving groundwater and enhancing climate resilience.

Key Facts

Through this project, potable water will be provided through bulk water systems, consisting of intakes, water treatment plants and transmission mains that will be connected to grid with existing and new systems in these three districts. The project will use high-technology based smart water management system to efficiently manage services. It will be first of its kind technology to be used for large scale rural water schemes in India.

The total cost of project is $349 million, for which ADB will provide loan of $240 million and grant of $3 million will be provided from Japan Fund for Poverty Reduction financed by Government of Japan. The West Bengal government will provide $106 million in funding. The project is due for completion in June 2024. This project will play important role in capacity building of institutions and stakeholders involved in delivering drinking water services.


High arsenic and fluoride levels in drinking water are serious threat to public health in India. About 85% of water in India’s rural areas comes from groundwater and around 27 million people are at risk from arsenic and fluoride contamination. West Bengal is by far worst affected state in high arsenic and fluoride levels in drinking water in India. Arsenic in drinking water can lead to range of serious health problems including cancer, while high exposure to fluoride can cause dental or skeletal fluorosis and bone diseases.
