The Largest Oil Field in India is the Mumbai High, formerly Bombay High. It is an offshore oil field located in the Arabian Sea. An oil field is an area of land that is used to extract petroleum, such as natural gas or oil, from the land. In other words, an oil field is a piece of land below which fossil fuels can be extracted for economic value.

Largest Oil Field in India

Most of India’s oil reserves are associated with anticlines and fault traps in the Tertiary sedimentary rock formations, from about 3 million years ago.

An oil field must meet three basic conditions:

  • Porosity to hold a sufficient volume of oil
  • After drilling, the well’s permeability to the release of gas and/or oil
  • To stop the oil from dispersing by percolating into the surrounding rocks, conglomerates of fractured limestone containing oil should be covered with porous sand bed sandstone, impermeable beds.
