Distributions of Giant Fields Found duirng 2000-2005 I Global distribution of giant fields II Discovery trend and outlook of energy supply III Plate tectonics and Basin classification IV Distribution of giant fields in different types of basins V Summary LECTURE OUTLINE 1. Discovery of giant fields peaked in 1960s and 1970s. 2. Most of the giants fields discovered are in basins with known petroleum, indicating exploration potential in these basins. 3. Few major new oil/gas basins have emerged. 4. Deepwater giants contribute significantly to the giant field inventory 全球21世纪发现的大油气田区域分布图 33155 mmbo 314.6 tcf (89,083亿方) 33155 mmbo 314.6 tcf (89,083亿方) 远景资源量 1086亿吨 地质资源量 765亿吨 探明储量 248亿吨 待探资源量 517亿吨 可采资源量 212亿吨 探明可采储量 70亿吨 待探明可采资源量 142亿吨 剩余可采储量 25亿吨 全国石油资源评价结果 远景资源量 55.9万亿方 地质资源量 35万亿方 探明储量 4.4万亿方 待探资源量 30.6万亿方 可采资源量 22亿吨 探明可采储量 2.8万亿方 待探明可采资源量 19.2万亿方 剩余可采储量 2.4万亿方 全国天然气资源评价结果 2、中国油气资源量、储量、产量 115个盆地 Distribution of Oil and Gas Fields in China Red: oil field Orange: gas field Oil is first found in the minds of men. Oil exploration is a dynamic art. Never say “never”. ‘Never-Say-Never’ to Exploration Areas New Ideas New Tools Changed Economics New Discoveries in ‘Old’ Areas Exploration strategies for senior managers of COC 1. There are still giant fields to be discovered; 2. Giant fields can be found in the following areas: mature basins: new idea (new plays, e.g. Penglai 19-3 new idea + new technology, GOM sub-salt) mature basins: old idea but new technology (e.g. Qianmiqiao) basin with low exploration maturity: play ideas in mature basins (analogue), both new and old technologies. 3. Reserves additions are largely from basins with known oil in USA. Producing basins should be remained as our main regions.
