  • Albertine Graben is one of the hot regain of oil and gas exploration in the world, with the geological features of shallow layer, rapid evolution, and new formation. Cenozoic layer is the primary target, where un-consolidated sandstone is the reservoir type with quite different reservoir parameters. On the effect of porosity and pore-filled fluid, the seismic reflection response of hydrocarbon bearing reservoir has no rules. It is difficult to make hydrocarbon detection in Albertine Graben. The match pursuit algorithm is used to raise the time-frequency resolution in the seismic instantaneous spectral decomposition. With the help of energy absorption analysis method, the instantaneous energy anomaly attribute is proposed based on match pursuit. W oilfield is taken for example in Albertine Graben; we found the rule of hydrocarbon bearing reservoir with low-frequency energy raised and high-frequency energy attenuated. We made hydrocarbon prediction using the instantaneous energy anomaly attribute, which was verified by the drilled well.
