Natural gas such as those in Siberia. Hydrates require a combination of high pressure and low temperature to form. In 2010, the cost of extracting natural gas from crystallized natural gas was estimated to be as much as twice the cost of extracting natural gas from conventional sources, and even higher from offshore deposits. In 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) announced that they had recovered commercially relevant quantities of natural gas from methane hydrate. The image below is a schematic block flow diagram of a typical natural gas processing plant. It shows the various unit processes used to
Billion cubic metres of natural gas Billion cubic metres of natural gas Billion cubic metres of natural gas (abbreviated: bcm) is a measure of natural gas production and trade. Depending of implied standards, this measure may represent different value of energy content. According to the standard defined by the International Energy Agency, it corresponds in average to of energy in the case of Russian natural gas and of energy in the case of Qatar's natural gas. According to the standard defined by the International Energy Agency, the gas physical volume is used, which is measured at the temperature of at atmospheric pressure. According to the Russian
