Natural gas in the United States natural gas and natural gas liquids. The exploration for and production of natural gas and petroleum form a single industry, and many wells produce both oil and gas. Because of the greater supply, consumer prices for natural gas are significantly lower in the United States than in Europe and Japan. The low price of natural gas, together with its smaller carbon footprint compared to coal, has encouraged a rapid growth in electricity generated from natural gas. Between 2005 and 2014, US production of natural gas liquids (NGLs) increased 70%, from 1.74 million barrels per day in 2005 to 2.96 million
Carbon capture and storage (timeline) Sleipner field produces natural gas and light oil from the Heimdal sandstones, which are about 2,500 m below sea level. The natural gas produced at Sleipner contains unusually high levels (about 9%) of carbon dioxide, but the customers require less than 2.5%. To encourage companies to cut their carbon emissions, the Norwegian government imposes a carbon tax equivalent to about $50 per ton of CO released into the atmosphere. To avoid paying the tax, and as a test of alternative technology, all of the CO extracted since 1996, when gas production started at Sleipner, has been pumped back deep underground.
