... to accurately and effectively identify the good reservoir. In this paper, in order to identify the good reservoir in the target zone, a new method combination based on AFFA and LFCA is proposed. Firstly, using the advantage feature fusion attribute (AFFA) analysis, we can reduce the effect of thin layer tuning...

... ABSTRACT We proposed a seismic weak reflection estimation method based on atomic norm optimization. Here we estimate the weak reflections which are submerged in the thin layers. Atomic norm optimization decomposes the frequency spectrum of the signal into some single-frequency atoms. One...

... ABSTRACT Frequency-dependent characteristics are investigated by the acquisition of seismic data using a physical model with horizontal fractures. The model consists of thin interbedded layers containing horizontal aligned fractures. In the model, 10 thin layers are set, and four different...

... of single fractured thin layer based on Chapman’s multi-scale rock physical model, we discuss the frequency-dependent effects as the various of type of fluid, fracture density and fracture scale. The fracture in our study is horizontal, making the media a VTI model. We find that the influence...

The spectral inversion method of thin layer is a new high precision inversion method, which is based on the combination of spectral decomposition technique and nonlinear inversion algorithm. This method can greatly improve...
