How Gas is Formed & Produced

How Gas Was Formed

  • Millions of years ago, plants and animals at the bottom of the ocean began to decay
  • As this organic material was heated and subjected to pressure from rock it eventually became methane gas
  • Today, geologists are still locating large reserves of natural gas here in the United States

How We Produce Natural Gas


  1. Rotary rigs drill through the rock to release the gas
  2. Gas travels through underground pipelines to a cleaning plant where the gas is cleaned of oil, water and other chemical impurities
  3. After processing, the gas is fed into a nationwide system of underground pipes and delivered to GRU for distribution to homes, businesses and industries
