Reserve Restatement 2007
In 2007, Occidental completed an exchange of oil and gas interests in Horn Mountain with BP for oil and gas interests in the Permian Basin and a gas processing plant in Texas. Occidental also sold its oil and gas interests in Pakistan to BP in 2007. In 2006, Ecuador terminated Occidental’s contract for the operation of Block 15, which comprised all of its oil-producing operations in the country, and seized Occidental’s Block 15 assets. Occidental has classified its Horn Mountain, Pakistan and Ecuador operations as discontinued operations on a retrospective basis and excluded them from all tables in the Supplemental Oil and Gas Information section.

The restated figure is 3724 bcf where it was previously 3810 bcf.
