Title: Gas-bearing reservoir prediction by elastic impedance inversion
Abstract: On basis of the principle of the prestack elastic impedance inversion,we present in this paper an idea to predict gas-bearing reservoir using the prestack elastic impedance inversion.Firstly we calculate elastic impedance curves of traces near wells.Secondly we transform prestack seismic data from offset domain to angle domain.Thirdly we estimate seismic wavelets corresponding to different angles.Then we perform inversion to obtain elastic impedance sections.Finally we extract various elastic parameters.Applications of this prestack elastic impedance inversion to seismic data from Block A,Erdos Basin obtain good results,and demonstrate its feasibility and effectivity of gas-bearing reservoir prediction.
