Survey of Energy Resources Interim Update 2009

Natural Gas update

As is the case with oil, proved recoverable reserves of natural gas show a moderate (in this instance, 2.2%) overall increase between end-2005 as quoted in the 2007 SER and end-2007 as compiled for the present interim update. Fig. 3 demonstrates that gas reserves in three countries (Iran, the USA and Kuwait) have each risen by around a trillion cubic metres, while those of Kazakhstan have fallen by a similar amount. In all, eleven countries account for the bulk of the changes in reserve levels, with the changes in 41 other countries (out of a total of 103 listed as possessing gas reserves) effectively netting off to zero. Brief details of the principal movements in gas reserves are given in the Country Notes below.

Table 5.1  provides a country-by-country listing (in billion cubic metres and billion cubic feet) of proved recoverable natural gas reserves at end-2007. The 2007 levels of marketed gas production, after allowance for re-injection, flaring and shrinkage (due to extraction of NGLs), are shown in Table 5.2.
