2. NATURAL GAS

This data collection applies to natural gas, which comprises gases occurring in underground deposits, whether liquefied or gaseous, consisting mainly of methane. It includes both ‘non-associated’ gas originating from fields producing hydrocarbons only in gaseous form, and ‘associated’ gas produced in association with crude oil as well as methane recovered from coal mines (colliery gas) or from coal seams (coal seam gas). It does not include gases created by anaerobic digestion of biomass (e.g. municipal or sewage gas) nor gasworks gas. The following list of aggregates shall be declared for all energy products listed in the previous paragraph unless otherwise specified. To be declared are quantities expressed in both volume and energy units, and including the gross and net calorific values, for the following aggregates: 1. Indigenous production All dry marketable production within national boundaries, including offshore production. Production is measured after purification and extraction of NGLs and sulphur. Excludes extraction losses and quantities reinjected, vented or flared. Includes quantities used within the natural gas industry; in gas extraction, pipeline systems and processing plants. 1.1. Of which: associated gas Natural gas produced in association with crude oil. 1.2. Of which: non-associated gas Natural gas originating from fields producing hydrocarbons only in gaseous form. 1.3. Of which: colliery gas Methane produced at coal mines or from coal seams, piped to the surface and consumed at collieries or transmitted by pipeline to consumers. 2. From other sources Fuels which are blended with natural gas, and consumed as a blend. 2.1. Of which: from oil products LPG for upgrading the quality e.g. heat content. 2.2. Of which: from coal Manufactured gas for blending with natural gas. 2.3. Of which: from renewables Biogas for blending with natural gas. 3. Imports 4. Exports 5. International marine bunkers 6. Stock changes A stock build is shown as a negative number and a stock draw is shown as a positive number. 7. Gross consumption 8. Statistical differences The requirement of declaring calorific values is not applicable here. 9. Recoverable gas: opening and closing stocks Quantities of gas available for delivery during any input-output cycle. This refers to recoverable natural gas stored in special storage facilities (depleted gas and/or oil field, aquifer, salt cavity, mixed caverns, or other) as well as liquefied natural gas storage. Cushion gas should be excluded. The requirement of declaring calorific values is not applicable here. 10. Gas vented The volume of gas released into the air on the production site or at the gas processing plant. The requirement of declaring calorific values is not applicable here. 11. Gas flared The volume of gas burned in flares on the production site or at the gas processing plant. The requirement of declaring calorific values is not applicable here. 12. Total transformation sector Quantities of fuels used for the primary or secondary conversion of energy (e.g. natural gas to electricity) or used for the transformation to derived energy products (e.g. natural gas to methanol). 12.1.

Energy quantities Unless indicated differently, quantities of natural gas are declared by its energy content, i.e. in TJ, based on the gross calorific value. Where physical quantities are required, the unit is in 10^(6) m^(3) assuming reference gas conditions (15 ^(o)C, 101,325 kPa). 2.
