Natural gas high pressure (petroleum and gas production offshore)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product ‘natural gas high pressure' is a fossil fuel for which a generic gross calorific value (GCV) of 40MJ/m3 a net calorific value (NCV) of 36.0 MJ/m3 and a density of 0.735kg/m3 for natural gas are applied in line with the global statistics (referring to standard cubic meters Sm3 measured at 15°C and 1013 mbar). It is used as a gaseous fuel and is sourced from oil and gas production and evaporation of liquid natural gas. The initial overpressure of the gas is 1-5 bar (1000-5000 hPa). Natural gas supplied at high pressure is predominantly used by large consumers e.g. power plants and industries. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
