In 2012, the Company made outstanding achievements in exploration activities with breakthroughs in shallow water and deepwater offshore China as well as overseas. Among a total of 21 new discoveries and 19 successful appraisals of oil and gas structures, Penglai 9-1, Dongfang13-2 and Qinhuangdao 29-2/29-2 East all have the potential to be developed into large sized oil and gas fields. The Company's reserve replacement ratio amounted to 188% during the year.
The projects that were planned to come online in 2012 all commenced production within the year, and Penglai 19-3 oilfield was given the green light in February, 2013 to gradually resume production. Having benefitted from the production contribution of the new oil and gas fields and good performance of the producing oil and gas fields, the Company's oil and gas production maintained a steady growth and reached 342.4 million barrels of oil equivalent ("BOE"), representing an increase of 3.2% year-over-year ("yoy"). The Company is fully confident to achieve its 2011 to 2015 production CAGR target.

In 2012, the Company's average realized oil price amounted to US$110.48 per barrel and its average realized natural gas price reached US$5.77 per thousand cubic feet, representing an increase of 0.7% and 12.0% yoy, respectively. The Company's oil and gas sales revenue reached RMB194.77 billion, up by 2.9% yoy, and the net profit was RMB 63.69 billion, a decrease of 9.3% yoy primarily caused by the increased tax and exploration expenses.

During the period, attributed to the factors including the imposition of the resource tax, the Company's all-in cost rose 16.8% yoy to US$35.73 per BOE.

In 2012, the Company's total capital expenditure reached approximately US$9.2 billion, up 43.1% yoy.
