The Group had total assets of approximately RMB billion.

5 CNOOC SZ Branch Overview Name CNOOC China Ltd._ Shenzhen : Established in 2000 Staff:3,500 (in 2014) Engaged in oil and gas exploration, development and production through joint venturing and independent operation in the eastern area of South China Sea. Pearl River Mouth Basin

6 Company History 1981 Pearl River Mouth Preparation Agency 1983 CNOOC Nanhai East Corporation 1999 CNOOC China Ltd._ Shenzhen 2009 CNOOC NanHai East Petroleum Bureau Since the establishment of CNOOC Nanhai East Corporation in June 1983, we have established cooperation with 14 countries and regions (Including America, Japan, Britain, France, Italy, Norway) and more than 50 companies for the exploration and development of oil and gas resources in the eastern area of the South China Sea. Since 1990, the first cooperative oil field set on production, we have put more than 25 Oil Fields and 5 Gas Fields successfully into production. By the end of 2014, we had for 19 consecutive years achieved equivalent oil and gas production of over 10 million cubic meters annually. In the process of developing international cooperation, the advanced technology and management were introduced from international oil companies. Through the combination of practice and experience, we have formed our unique management style with win-win culture. 6

8 勘探历程 Exploration History Phase 1:regional prospecting ( 油气区域普查 before 1979); Phase 2:cooperative exploration( 对外合作 ); Phase 3:independent & cooperative exploration ( 自营合作并举 since 2000);

9 Phase 1:regional prospecting The petroleum and geology units conducted gravitational prospecting, magnetic prospecting and seismic acquisition from 1974 to 1976 in south China sea. Seven wild cat were drilled during 1977 to The well Zhu 5 has got the successful DST test with 1,822 barrels oil per day. 年份 1980 前 井号 完钻井深油气油气显示井干井米流井层井 ZHU ZHU ZHU ZHU ZHU ZHU

10 Phase 2:cooperative exploration ( ) When the State Council implemented the Regulation of the Petroleum Resources in Cooperation with Foreign Enterprises on January 30, 1982, CNOOC was incorporated and authorized to assume overall responsibility for the exploitation of oil and gas resources of offshore China in cooperation with foreign partners. Since 1980, numerous seismic campaigns (2D & 3D) have been carried out, and more than 250 exploration and appraisal wells have been drilled. 10

11 Phase 3:Independent & Cooperative Exploration (since 2000) 历年 2D 采集情况 2D 地震 243,436km( 自营 120,153km, 合作 123,283km) 自营合作 公里 年度 历年 3D 采集情况 3D 地震 32,275km 2 ( 自营 14,914km 2, 合作 17,361km 2 ) 自营合作 平方公里 年度 历年钻井 自营 20 合作 累计钻探井 267 口 ( 自营 90 口, 合作 177 口 ) 钻井数 对外合作阶段 年度 自营合作并举阶段

12 Phase 3:Independent & Cooperative Exploration (since 2000) Zhuhai Terminal LW3-1:1 st deepwater gas field Water depth of 1500 meters Proven OGIP:475.81x10 8 m 3 Annual Gas Production: 36.2x10 8 m 3 PY30-1 DPP LH19-5 Gas Field BY-LW deepwater area in Pearl River Month basin lies on a slope zone along the northern shelf margin, South China Sea. It has been proved by the recent several gas discoveries on the north slope of BY-sag and the breakthrough in LW3-1 gas area that this sag is abundant in hydrocarbon generation. More than 10 gas fields have been discovered in Southern part of the PRMB, the OGIP: 5.64 tcf.

19 The Second Leap Forward Development Programme 类别 2015 年 2020 年 有限公司国内目标 ( 万吨 ) 6,000-6,500 7,000 深圳分公司奋斗目标 ( 万吨 ) The13 rd five years Oil and Gas development plan of CCLS was based on the Second Leap Forward Development Programme of CNOOC. 2. Relying on the existing facilities of deepwater gas project to push the gas production to higher level ( m 3 per year); 3. Enhancing deepwater oil exploration and engineering innovation to keep oil production over m 3.

20 Rolling exploration around developed shallow water area strengthening exploration on mid-large size targets and combined new area exploration, m 3 oil and 5.6 tcf gas resources are quite expectable in the next decade.
