The correct option is 2 only
Explanation
Natural gas is a fossil fuel primarily composed of methane. It is formed deep beneath the earth's surface and is extracted from sedimentary basins. It serves as a critical energy source and a feedstock for various industrial applications.
Statement-wise Analysis
- Statement 1 is Incorrect: Natural gas is extensively used as a raw material (feedstock) in the petrochemical industry. It is crucial for the manufacturing of fertilizers (specifically urea), plastics, and other synthetic materials. In India, the fertilizer sector is the largest consumer of natural gas.
- Statement 2 is Correct: Natural gas is frequently found in association with petroleum deposits. When found with crude oil, it is termed "associated gas." It can also be found in reservoirs that contain gas but no oil, known as "non-associated gas." Therefore, the claim that it is never found with petroleum is factually wrong.
- Statement 3 is Incorrect: While significant natural gas reserves in India are located in offshore regions (such as the Mumbai High and the Krishna-Godavari basin), they are not restricted to these areas. Substantial onshore reserves exist in states like Assam, Gujarat, Tripura, Rajasthan, and Tamil Nadu.
Key Takeaway
Key Takeaway: Natural gas is a versatile fossil fuel found in both onshore and offshore sedimentary basins, often in association with crude oil. It is a primary feedstock for the fertilizer and petrochemical industries.
