Natural gas before the natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not truly produced up the annulus and through a casinghead outlet) or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging resource types: sour gas, tight gas, shale gas, and coalbed methane. There is some disagreement on which country has the largest proven gas reserves. Sources that consider that Russia has by far the largest proven reserves include the US CIA (47 600 km³), the US Energy Information Administration (47 800 km³), and OPEC (48
Natural gas in Bolivia oil production really peaked, only to be followed by a decline in the next decade. That is when natural gas overshadowed oil and tin to become the main hydrocarbon exported by the country up to this date. Since the 1980s, the number of known reserves has increased substantially. It was during the 1990s that new major discoveries really increased natural gas production in Bolivia. “Major discoveries of natural gas since 1996 had boosted proven and probable gas reserves almost tenfold, to 48.7trn cu ft, by the end of 2004” The rise of natural gas as Bolivia’s most important export occurred
