Coal is one of the most important primary fossil fuels, a solid carbon-rich material that is usually brown or black and most often occurs in stratified sedimentary deposits. Coal is a natural resource that can be used as a source of energy, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power using steam generation. In addition, gasification and liquefaction of coal produce gaseous and liquid fuels that can be transported by pipeline and stored in tanks.

It is a bill to amend the Oilfields (Regulation and Development) Act, 1948, aiming to boost investment in oil and gas exploration and production. The bill will regulate the exploration and extraction of natural gas and petroleum. The amended bill expands the definition of mineral oils to include petroleum and natural gas in it. The amended bill includes any naturally occurring hydrocarbon, coal bed methane, and shale gas/oil in the category of mineral oils. However, it clarifies that mineral oils will not include coal, lignite, or helium.

A petroleum basin includes a diverse collection of rocks and sediments, but most importantly it contains source rocks. Source rocks are specific shale formations in a basin where oil and gas are born. There are 26 sedimentary basins in India, covering a total area of 3.4 million square kilometer. Of the total sedimentary area, 49% of total area is located on land, 12% in shallow water (up to 400 meter water depth) and 39% in the deepwater area (farther up to Exclusive Economic Zone or EEZ). The jurisdiction of the EEZ extends 200 nautical miles from the coastline, thereby conferring on the coastal state the right to manage, explore, exploit, and conserve all resources within its purview, be they living or non-living.
