"We continue to have exceptional performance from our portfolio, as evidenced by the results delivered in the second quarter of 2013," said Anadarko Chairman, President and CEO Al Walker. "Our U.S. onshore activities delivered year-over-year oil growth of 25 percent, averaging approximately 97,000 barrels per day during the quarter. We continued to drive significant improvements into our drilling and completions programs, and costs in each category were favorable to our expectations. We reached milestones at four of our large global oil projects, which are advancing on schedule and on budget, and we achieved a success rate of almost 70 percent in our deepwater exploration/appraisal program, including five new discoveries. We also strengthened the balance sheet, improving our net-debt-to-adjusted-capitalization ratio⁽²⁾ to 29 percent compared to 34 percent at the end of 2012."

Operations Summary
Anadarko reported total sales volumes of more than 750,000 barrels of oil equivalent (BOE) per day during the second quarter. Liquids sales volumes averaged 309,000 barrels per day, without the benefit of an expected tanker lifting in Algeria, which is anticipated during the third quarter. Natural gas volumes averaged approximately 2.6 billion cubic feet per day. Anadarko is increasing its full-year 2013 sales volumes guidance to a range of 281 to 287 million BOE, from the previous range of 279 to 287 million BOE.

Anadarko's Wattenberg Horizontal program continued to deliver robust growth during the quarter, driving the field average to more than 60,000 barrels of liquids per day, representing an increase of more than 37 percent over the second quarter of 2012. The company's Eagleford Shale program also delivered higher liquids sales volumes, averaging approximately 32,000 barrels per day, representing a 62-percent increase over the second quarter of 2012. Additionally, Anadarko commenced operations at its 200-million-cubic-feet-per-day Brasada natural gas processing plant, significantly enhancing the company's takeaway capacity in the Eagleford Shale. In Anadarko's liquids-rich East Texas Horizontal program, sales volumes doubled from the second quarter of 2012 to approximately 40,000 BOE per day in the second quarter of 2013.

Mega-Project Summary
Anadarko reached significant milestones at four of its large-scale oil projects during the quarter. The Lucius development in the deepwater Gulf of Mexico remains on track for first oil in the second half of 2014. The company successfully transported its 80,000-barrels-of-oil-per-day (BOPD) Lucius spar from the fabrication yard in Pori, Finland, to Corpus Christi, Texas, with plans to install the spar in Keathley Canyon block 875 during the third quarter of 2013. Construction on the Heidelberg spar, which also has a capacity of 80,000 BOPD, is about 30-percent complete. During the quarter, the company and its partners officially sanctioned the Heidelberg development project and expect to achieve first oil in mid-2016.

In Algeria, the first oil train at El Merk continued to increase production throughout the quarter, and the second oil train is being commissioned. El Merk remains on schedule to ramp toward a net rate of approximately 30,000 barrels per day by the end of 2013.

In Ghana, the government approved the Plan of Development for the TEN (Tweneboa, Enyenra, Ntomme) project during the quarter, which will be the partnership's second major oil development offshore Ghana, with an 80,000-BOPD facility expected to begin production in 2016.
