Why in news?

Union Minister for Petroleum and Natural Gas dedicates the 8th producing Basin of India, Bengal Basin, to the nation.

Sedimentary basins:

  • Sedimentary basins are the primary locations on the continents where sufficient subsidence exists for long-term preservation of continental sediments.
  • As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction and lithification that transform them into sedimentary rock.
  • Sedimentary basins are of great economic importance. Almost all the world’s natural gas and petroleum and all of its coal are found in sedimentary rock.

Sedimentary basins in India:

  • India has 26 sedimentary basins covering an area of 3.14 million square kilometres. These include 16 on-land basins, 7 part on-land and part offshore and 3 completely offshore basins.
  • These basins are divided into three categories based on the maturity of hydrocarbon resources as under:
    • Category-I: Basins which have reserves and already producing.
    • Category-II: Basins which have contingent resources pending commercial production
    • Category-III: Basins which have prospective resources awaiting discovery
  • There are 7 Category-I Basins (to which now, the 8th one, Bengal Basin, has been added).

The 7 basins with commercial production are:

    • Cambay
    • Assam Shelf
    • Mumbai offshore
