"Volume of flared and vented hydrocarbon"

"There was a significant increase in flaring at both Gloucester and Silver Springs. The increase at Gloucester was due to an increase in gas extraction for pilot testing, all of which was flared. At Silver Springs the increase in flaring was due to works being undertaken at the plant which did not allow the gas to be injected into storage, and was instead sent to flare. This flaring increase has in turn led to an increase of the proportion of hydrocarbons vented or flared compared to the amount of oil and gas produced."

Notes
"Includes gas venting, gas flaring and fugitive leaks from equipment and pipelines at AGL's operated oil and gas producing facilities, including exploration projects and those in development."
"The data above does not include vented and flared hydrocarbons from the Newcastle Gas Storage Facility as this facility does not produce oil or gas. However, the volume of flared and vented hydrocarbons from the Newcastle Gas Storage Facility was 124 tonnes over FY2015.  Vented emissions from the storage aspects of Silver Springs are included above."
"The total tonnes of gas vented and flared at each facility has been calculated in accordance with the National Greenhouse and Energy Reporting Act, and includes the use of default (method 1) emission factors for some sources of venting and general fugitive leaks.  "
"To calculate the total vented and flared hydrocarbons relative to total production, all oil and gas production is taken into account, including production used on site, and production vented and flared.  "
"Amount of hydrocarbon has been rounded to the nearest tonne."
"FY2016 data was updated on 1 November 2016.  Data was not available at the time of the initial release of the FY2016 Sustainability Report on 10 August 2016."
