20、exploration areas and plays?Large resource base,bright exploration futureBy end of 2005,6,963 million tonnes of oil in place had been proven.The discovery maturity is around 33%and the exploration maturity is moderate.Oil exploration potential is considered to be significant.By the same year end,3.5

21、 TCM of gas in place had been proven.The discovery maturity is around 16%and the exploration is in the early to intermediate stages.Gas exploration potential is tremendous.a.Intra-continental foreland basins and mountain front thrust beltsb.Paleo-uplifts and their slopes in cratonic basinsc.Large scale stratigraphic and lithological playsd.Offshore areas?Exploration areas and plays
