Mumbai High, formerly Bombay High, is India's largest oil field. It is an offshore oil field located in the Arabian sea. An oil field is an area of land used to extract petroleum, such as natural gas or oil, from the ground. In other words, an oil field is a piece of land beneath which fossil fuels can be extracted for economic value.

Oil field in India

  • Most of India's oil reserves are associated with anticlines and fault traps in the Tertiary sedimentary rock formations, about 3 million years ago.
  • An oil field must meet three basic conditions
    • Porosity to hold a large enough amount of oil
    • Permeability to release oil and/or gas when the well has been drilled
    • Porous sand bed sandstone, impermeable beds should cover conglomerates of fractured limestone containing oil to prevent the oil from dispersing by percolating into the surrounding rocks.
  • The biggest success achieved by ONGC concerning offshore oil exploration was in 1974 at Mumbai High.
  • It is located on the continental shelf off the coast of Maharashtra, about 176 km northwest of Mumbai.
  • Here, the Miocene age rock layers cover an area of 2,500 square km with estimated reserves of about 330 million tons of oil and 37,000 million cubic meters of natural gas.
  • Commercial-scale production began in 1976.
  • Oil is extracted from a depth of over 1,400 meters using a specially designed platform known as the Sagar Samrat.
