Summary
Worldwide energy demand is continuously increasing with the current pace of development and oil continues to play a crucial role in total energy mix. It is becoming difficult to meet the demand of crude oil with existing light and medium crude oilfields as production from these fields which are mostly in matured stage, are declining. This has necessitated more attention for increasing the exploitation of heavy and extra heavy oilfields. Right here, seismic reservoir characterization of heavy oil is becoming an increasingly important reservoir characterization method, in which we need to take full advantage of seismic processing, pre-stack simultaneous AVO inversion, rock physics modeling, shear wave slowness prediction, lithology/fluid prediction and rock physics inversion. In the following case study in offshore Eastern China, the products from the study are intended to provide the basis for the quantification of hydrocarbon pore volume, interpretations of reservoir morphology, and information required for reservoir simulation, field development planning and implementation.
