Vietnam has 600 million barrels of proven Oil reserves, according to data from Oil and Gas Journal, but that total is likely to increase as exploration continues. Crude Oil production averaged 370,000 barrels per day (bbl/d) in 2005, down somewhat from the 403,000 bbl/d level achieved in 2004. Bach Ho (White Tiger), Rang Dong (Dawn), Hang Ngoc, Dai Hung (Big Bear), and Su Tu Den (Ruby) are the largest oil producing fields in the country. Although it is a significant oil producer, Vietnam remains reliant on imports of Petroleum products due to a lack of refining capacity. Overall, Vietnam had net exports of 111,000 bbl/d of oil in 2005. Most of Vietnams crude oil is exported to refiners in Japan, Singapore, and South Korea.
