Survey of Energy Resources 2007

Natural Gas Country Notes

The Danish WEC Member Committee quotes the Danish Energy Authority (DEA), which does not use the terms proved and additional reserves, but employs the categories 'ongoing', 'approved', 'planned' and 'possible recovery'. The DEA expresses natural gas volumes in normal cubic metres (Nm3), measured at 0oC and 1 013 mb. For the purposes of the present Survey, all such data have been converted to standard cubic metres, measured at 15oC and 1 013 mb.

The figure for proved recoverable reserves (82 bcm) has been derived from the sum of 'ongoing' and 'approved' reserves (78 billion Nm³), while the figure for additional reserves recoverable (45 bcm) has been derived from the sum of 14 billion Nm³ 'planned' and 29 billion Nm³ 'possible' reserves. Of the reported proved recoverable reserves, 44% is non-associated with crude oil. The Danish Member Committee also reports the amount of gas in place corresponding to the proved recoverable reserves as 564 bcm and that corresponding to the additional reserves recoverable as 53 bcm.
