Vertical axis in chart corresponds to billions of cubic metres of sales gas per year
Gas - sales gas from on and offshore reservoirs, including tight sands/shales and coal beds
Full number breakdowns are available in the Datafiles area of this site
Gas Delivery
Pipeline Sales Gases - are defined as gases that have been, or will be, extracted from any type of reservoir, then delivered to the ultimate consumer by a pipeline network, before or after compression. This does not include gases that are delivered to a Liquefied Natural Gas Plant for conversion to LNG.
Liquefied Natural Gases (LNG) - are defined as gases that have been, or will be, extracted from any type of reservoir. They are, in an industrial plant, condensed into a liquid to form LNG for storage in refrigerated conditions until used by a consumer.

Fossil (Sales*) Gases
1. Field Gases - are defined as fossil hydrocarbon gases that have been, or will be, extracted through wells from an oil, wet gas, or oil and gas field made up of one or more porous and permeable reservoirs. Gases are volumetrically measured at surface temperatures and pressures. They may also be called conventional gases. After extraction of liquids they are sold for use as a direct energy source, or for conversion to Liquefied Natural Gas (LNG) or electricity, or for use in the chemicals industry.
2. Coal Bed Methanes (CBM) - are defined as fossil hydrocarbon gases that have been, or will be, extracted from coal seams revealed in coal mining operations, through wells or by other means. The gases are volumetrically measured at surface temperatures and pressures.
3. Shale/Tight Gases (STGs) - are defined as gases that have been, or will be, extracted through wells, from tight (shales, as well as sandstones or carbonates), non-field, dispersed reservoirs before or after underground artificial fracturing.
* Unsold vented, flared, and re-injected gases as well as gases used on site are currently not included in the reported numbers.
Produced Gases
Production (Onshore) - gas production numbers include associated and free hydrocarbon gases from onshore wells (including those drilled within lakes, swamps and on piers), regardless of subsurface location. Unsold vented, flared, and re-injected gases as well as gases used on site are not included.
Production (Offshore, split by water depth) - gas production numbers include associated and free hydrocarbon gases from offshore wells (including those drilled from fixed platforms and artificial islands unconnected to the mainland). Unsold vented, flared, and re-injected gases as well as gases used on site are not included. ‘Very shallow waters’ are defined as output from reservoirs down to 100m, ‘medium shallow waters’ from >100 to 500m, ‘medium deep waters’ from >500 to 1000m, ‘very deep waters’ from >1000 to 2000m, and ‘ultra deep waters’ from > 2000m.

Types
There are 3 gas types split onshore and offshore by water depth and other categories.
