  • Union Ministry of Petroleum and Natural Gas has amended Petroleum and Natural Gas Rules 1959 to include shale in the definition of petroleum.
  • This change will allow private companies to explore and produce the resource in the blocks they already operate.
  • Earlier, definition excluded shale and therefore barred companies from exploiting it from fields that are producing conventional oil and gas or coal-bed methane.
  • Shale is distinguished from other mudstones due to laminated and fissile nature.
  • Shale gas is natural gas formed from being trapped within shale formations.
  • Shale gas is cheaper than natural gas, releases 50% less CO2, hence better source for generating electricity.
  • In India, potential shale gas sites are Cambay, Gondwana, Krishna-Godavari and Cauvery Basins.
