Difficulty: MediumMineral and Energy Resources of India

Consider the following statements regarding the petroleum and natural gas resources of India:

1. Digboi in Assam is the oldest operating oilfield in India, with petroleum trapped primarily in Tertiary sedimentary rock formations.
2. The Mumbai High offshore oilfield is located on the continental shelf of the Arabian Sea and contributes a major share of India's domestic crude oil production.
3. The Krishna–Godavari (KG) offshore basin in the Bay of Bengal contains significant deep-water natural gas reserves.

Which of the statements given above are correct?

  1. A
    1 and 2 only
  2. B
    2 and 3 only
  3. C
    1 and 3 only
  4. 1, 2 and 3Answer

Answer

All three statements (1, 2, and 3) are correct.
The statement including 1, 2, and 3 is correct because Digboi is India's pioneer oilfield set in Tertiary formations, Mumbai High is the premier continental shelf crude oil producer in the Arabian Sea, and the KG basin holds major deep-water natural gas reserves.

Step-by-Step Solution

1
Evaluate Statement 1 regarding Digboi oilfield
Statement 1 is correct.
Digboi in Assam is India's oldest operational oilfield (drilled in 1889). Hydrocarbons in northeast India are predominantly associated with Tertiary sedimentary rock structures.
2
Evaluate Statement 2 regarding Mumbai High
Statement 2 is correct.
Mumbai High (discovered in 1974) lies on the continental shelf off the Mumbai coast in the Arabian Sea and remains one of the largest producers of domestic crude oil.
3
Evaluate Statement 3 regarding Krishna–Godavari basin
Statement 3 is correct.
The Krishna–Godavari (KG) offshore basin along the eastern coast (Bay of Bengal) is known for major deep-water natural gas deposits.
