Difficulty: EasyMineral and Energy Resources of India

Arrange the following major oil refineries of India in order from West to East based on their geographical location:

  1. 1Jamnagar Refinery (Gujarat)
  2. 2Mathura Refinery (Uttar Pradesh)
  3. 3Barauni Refinery (Bihar)
  4. 4Digboi Refinery (Assam)

Answer

The correct longitudinal order from West to East is Jamnagar Refinery (Gujarat), Mathura Refinery (Uttar Pradesh), Barauni Refinery (Bihar), and Digboi Refinery (Assam).
Jamnagar in Gujarat lies at the westernmost end of India (~70.0° E longitude). Moving east, Mathura in Uttar Pradesh sits at ~77.6° E, Barauni in Bihar at ~85.9° E, and Digboi in Assam at ~95.6° E near the eastern frontier.

Step-by-Step Solution

1
Identify the geographical state location of each petroleum refinery.
Jamnagar is in Gujarat, Mathura is in Uttar Pradesh, Barauni is in Bihar, and Digboi is in Assam.
Determining state locations helps align the refineries along longitudinal lines across India.
2
Arrange the states from west to east across the Indian subcontinent.
Gujarat (Westernmost) -> Uttar Pradesh (North-Central) -> Bihar (Eastern) -> Assam (North-Easternmost).
India's longitude extends from roughly 68°7' E in Gujarat to 97°25' E in Arunachal Pradesh/Assam.
3
Formulate the final sequential order.
Jamnagar -> Mathura -> Barauni -> Digboi.
This places the refineries in strict West to East chronological spatial sequence.
