... in the working area. It can be seen that for some data points the average distortion + average force is more than 100%, which means that the source parameters are not suitable for the surface in the work area, and that the force level needs to be reduced. The impact of peak distortion on the seismic data...

.... Joint PP-PS AVO inversion simultaneously inverts multicomponent seismic data for physical rock properties to discriminate lithology and fluids. The joint inversion of PP and PS data takes advantage of the higher sensitivity of converted waves to shear impedance and density contrasts: this makes...

... and building models for predicting pore pressure where secondary overpressure mechanisms are observed in addition to undercompaction. Well logs and 3D seismic data were used to understand the evolution of pore pressure in the field. This was established from offset well data by making cross-plots of acoustic...

... Abstract Seismic interpretation is a key task and foundation for hydrocarbons exploration and field development. Seismic data provides coverage from basin to reservoir scale workflows for identifying regional structures, delineate prospects and calculate rock properties. In this paper we...

...Conclusion The paper has illustrated an attempt to leverage on seismic data for the derivation of lithology (Vshale) cube and using it as a lithology input for petroleum system modelling. The Vshale cube could provide detailed and improve characterization of lithology distribution, which...

... The geology-guided seismic data processing and integrated interpretations, along with seismic inversion, are applied in this study to improve our understanding of the complex reservoir sandstone distributions and water-oil contacts unveiled by the drilling data. The new processing mainly covered...

... the seismic data below the salt area, leading to a better seismic image quality and allowing us to focus on updating the velocity in target area below the salt. However, this redatuming approach requires a good overburden velocity model to retrieved good redatumed data. Thus, by using synthetic SEAM model...

... Abstract The biogas lithologic reservoirs in Sanhu Area of the Qaidam Basin has a broad exploration prospect, however, the demands of structural implementation and reservoir prediction can hardly be met with the existing P-wave seismic data due to the thin thickness of single sandstone layers...

... Abstract The space of fracture reservoir in granite buried hills varies sharply with strong heterogeneity and very difficult to predict. Conventional fracture prediction methods based on narrow-azimuth post-stack seismic data have low prediction accuracy. OVT pre-stack gather retains...
