Natural gas - high pressure (petroleum and gas production - offshore)

The activity generating the emissions is petroleum and gas production, offshore. The reference product is natural gas, high pressure. ‘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 reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
