In 2008, it had net oil exports of 1.189 Mbbl/d (189,000 m3/d) to the United States. As a result of the lack of transparency in the country's accounting, Venezuela's true level of oil production is difficult to determine, but OPEC analysts estimate that it produced around 2.47 Mbbl/d (393,000 m3/d) of oil in 2009, which would give it 234 years of remaining production at current rates. In 2010 Venezuela reportedly produced 3.1 millions barrels of oil daily and exporting 2.4 million of those barrels per day. Such oils exports brought in $61 billion for Venezuela. However, Venezuela only owned about $10.5 billion in foreign reserves, meaning that its debt remained at $7.2 billion when 2015 rang out.
