Kuwait has the world’s sixth largest oil reserves and is one of the ten largest exporters of total oil products. According to Oil & Gas Journal, as of January 2011, Kuwait’s territorial boundaries contained an estimated 101.5 billion barrels (bbl) of proven oil reserves, roughly 7 percent of the world total.
Additional reserves are held in the Partitioned Neutral Zone (aka Divided Zone), which Kuwait shares on a 50-50 basis with Saudi Arabia. The Neutral Zone holds an additional 5 billion barrels of proven reserves, bringing Kuwait's total oil reserves to 104 billion barrels.
