  • ONGC estimates India’s shale gas reserve in the range of 500 to 2000 trillion cubic meters.
  • Cambay is one of the basins that have been identified as potentially-bearing shale resources.
  • But apart from the Cambay basin, the ONGC will also explore Krishna-Godavari, Cauvery and Vindhyan sedimentary basins for shale gas in the near future.
  • Major regions of availability are Gujarat, Rajasthan, central India, KG Basin and offshore areas in Bay of Bengal.
