JODI-Gas Definitions - Acronyms and Abbreviations

Definitions

Natural gas:
Natural gas is defined as a mixture of gaseous hydrocarbons, primarily methane, but generally also including ethane, propane and higher hydrocarbons in much smaller amounts and some non-combustible gases such as nitrogen and carbon dioxide. It includes both non-associated gas and associated gas. Colliery gas, coal seam gas and shale gas are included while manufactured gas and biogas are excluded except when blended with natural gas for final consumption. Natural gas liquids are excluded.

Production:
Dry marketable production within national boundaries, including offshore production, measured after purification and extraction of NGL and sulphur. Production does not include quantities reinjected, extraction losses or quantities vented or flared. It should include quantities used within the natural gas industry, in gas extraction, pipeline systems and processing plants.

Receipts from Other Sources:
Gas from energy products that have been already accounted for in the production of other energy products. Examples include petroleum gases or biogases that have been blended with natural gas.

Imports/Exports:
Amounts are considered imported or exported when they have crossed the physical boundaries of the country, whether customs clearance has taken place or not. Goods in transit and goods temporarily admitted/withdrawn are excluded but re-imports, that is domestic goods exported but subsequently readmitted, are included (same for reexports).
Deliveries for international bunkers should be excluded.
