Kuwait, for example, was reported in the January 2006 issue of "Petroleum Intelligence Weekly" to have only in reserve, of which only 24 were fully proven. This report was based on the leak of a confidential document from Kuwait and has not been formally denied by the Kuwaiti authorities. This leaked document is from 2001, but excludes revisions or discoveries made since then. Additionally, the reported of oil burned off by Iraqi soldiers in the First Persian Gulf War are conspicuously missing from Kuwait's figures.
