Oil Production from Krishna Godavari Basin

Context: ONGC begins ‘first oil production’ from deep-water block (KG-DWN-98/2 Block)in Krishna Godavari basin.

ONGC Begins Oil Production from Krishna Godavari Basin

• Location: The block is located  approximately 25 km from the Kakinada coast in the Krishna Godavari basin off the Bay of Bengal 
• Expected production:
  • Approximately around 45,000 barrels per day & over  10 million cubic meters of gas per day.
  • It will add 7% to current national oil production & 7% to national Natural Gas production!
  • It will help increase the ONGC’s total oil production by 11% and natural gas production by 15%.”
• The final phase of the 98/2 block project is  to begin the production of the balance of oil and natural gas by mid-2024.

About Krishna Godavari Basin

• It is an Extensive deltaic plain formed by the  rivers, Krishna and Godavari in Andhra Pradesh  and  16 adjoining areas, of the Bay of Bengal on the East Coast of India
• The basin contains about 5 km thick sediments with several cycles of deposition, ranging in age from Late Carboniferous to Pleistocene.
• Major geomorphological units:  Upland plains, coastal plains, recent Floods, and delta plains.
• Hydrocarbon potential: The Krishna Godavari Basin is an established hydrocarbon province with a resource base of 1130 MMT, of which, 555 MMT are assessed for the offshore region.
• Petroleum System: It is a petroliferous basin with commercial hydrocarbon accumulations in the oldest Permo-Triassic Mandapeta Sandstone on land to the youngest Pleistocene channel levee complexes in deep water offshore. 
• • The basin’s petroleum systems can be classified into two categories viz. Pre-Trappean and Post-Trappean in view of their distinct tectonic and sedimentary characteristics
• Depositional systems: Godavari delta system, Masulipatnam shelf-slope system, Nizampatinam shelf –slope system and Krishna delta system.
