Geophysical recognition of subtle oil/gas reservoir in block 31-6 of Liaodong Bay.;

Identification of subtle oil/gas reservoir in Junggar Basin;

Prediction method and its preliminary application in predicting resource potentials of subtle oil/gas reservoirs;

Exploration of subtle reservoirs in the northern shelf basins of South China Sea;

The research results of high precision sequence stratigraphy in the Liaozhong Sag of the Liaodong Bay Basin are used to build up detailed sedimentary sections that can exhibit the subtle sandbodies,and Temis2D software of IFP is employed to model the subtle reservoirs forming process for the first time.
