Exploration and Production earnings were $527 million in the fourth quarter of 2011 compared with $420 million in the fourth quarter of 2010. The Corporation’s average worldwide crude oil selling price, including the effect of hedging, was $89.70 per barrel, up from $71.73 per barrel in the same quarter a year ago. The average worldwide natural gas selling price was $6.32 per Mcf in the fourth quarter of 2011, up from $5.30 per Mcf in the fourth quarter of 2010. Fourth quarter oil and gas production was 367,000 barrels of oil equivalent per day, compared with 420,000 barrels of oil equivalent per day in the fourth quarter a year ago, largely due to production interruptions and asset sales. Fourth quarter 2011 results included higher exploration expenses reflecting total dry hole costs of $236 million ($143 million after-tax), primarily associated with two exploration wells on the Semai V Block, offshore Indonesia.

Oil and gas proved reserves were 1,573 million barrels of oil equivalent at the end of 2011, compared with 1,537 million barrels at the end of 2010. During 2011, the Corporation added 203 million barrels of oil equivalent to proved reserves. These additions, which are subject to final review, replaced approximately 147 percent of the Corporation’s 2011 production, resulting in a reserve life of 11.4 years.
