Reservoir prediction using Poisson impedance in Qinhuangdao, Bohai Sea

Abstract

As an elastic parameter, Poisson impedance (PI) is very important for reservoir prediction and hydrocarbon detection in practical application. However, PI calculated by common C‐value methods is not accurate enough, which may affect reservoir prediction seriously. Therefore, this paper presents a new method for calculating C‐value via the target correlation coefficient analysis (TCCA). The proposed method is examined by real seismic data from Qinhuangdao, Bohai Sea. Test results show that the TCCA method can increase the accuracy of PI calculation, and may improve the reliability of reservoir prediction.
